中英文对照外文翻译文献(文档含英文原文和中文翻译)外文翻译：Thermocouple Temperatur sensorIntroduction to ThermocouplesThe thermocouple is one of the simplest of all sensors. It consists of two wires of dissimilar metals joined near the measurement point. The output is a small voltage measured between the two wires.While appealingly simple in concept, the theory behind the thermocouple is subtle, the basics of which need to be understood for the most effective use of the sensor.Thermocouple theoryA thermocouple circuit has at least two junctions: the measurement junction and a reference junction. Typically, the reference junction is created where the two wires connect to the measuring device. This second junction it is really two junctions: one for each of the two wires, but because they are assumed to be at the same temperature (isothermal) they are considered as one (thermal) junction. It is the point where the metals change - from the thermocouple metals to what ever metals are used in the measuring device - typically copper.The output voltage is related to the temperature difference between the measurement and the reference junctions. This is phenomena is known as the Seebeck effect. (See the Thermocouple Calculator to get a feel for the magnitude of the Seebeck voltage). The Seebeck effect generates a small voltage along the length of a wire, and is greatest where the temperature gradient is greatest. If the circuit is of wire of identical material, then they will generate identical but opposite Seebeck voltages which will cancel. However, if the wire metals are different the Seebeck voltages will be different and will not cancel.In practice the Seebeck voltage is made up of two components: the Peltiervoltage generated at the junctions, plus the Thomson voltage generated in the wires by the temperature gradient.The Peltier voltage is proportional to the temperature of each junction while the Thomson voltage is proportional to the square of the temperature difference between the two junctions. It is the Thomson voltage that accounts for most of the observed voltage and non-linearity in thermocouple response.Each thermocouple type has its characteristic Seebeck voltage curve. The curve is dependent on the metals, their purity, their homogeneity and their crystal structure. In the case of alloys, the ratio of constituents and their distribution in the wire is also important. These potential inhomogeneous characteristics of metal are why thick wire thermocouples can be more accurate in high temperature applications, when the thermocouple metals and their impurities become more mobile by diffusion.The practical considerations of thermocouplesThe above theory of thermocouple operation has important practical implications that are well worth understanding:1. A third metal may be introduced into a thermocouple circuit and have no impact, provided that both ends are at the same temperature. This means that the thermocouple measurement junction may be soldered, brazed or welded without affecting the thermocouple's calibration, as long as there is no net temperature gradient along the third metal.Further, if the measuring circuit metal (usually copper) is different to that of the thermocouple, then provided the temperature of the two connecting terminals is the same and known, the reading will not be affected by the presence of copper.2. The thermocouple's output is generated by the temperature gradient along the wires and not at the junctions as is commonly believed. Therefore it is important that the quality of the wire be maintained where temperature gradients exists. Wire quality can be compromised by contamination from its operating environment and the insulating material. For temperatures below 400°C, contamination of insulated wires is generally not a problem. At temperatures above 1000°C, the choice of insulationand sheath materials, as well as the wire thickness, become critical to the calibration stability of the thermocouple.The fact that a thermocouple's output is not generated at the junction should redirect attention to other potential problem areas.3. The voltage generated by a thermocouple is a function of the temperature difference between the measurement and reference junctions. Traditionally the reference junction was held at 0°C by an ice bath:The ice bath is now considered impractical and is replace by a reference junction compensation arrangement. This can be accomplished by measuring the reference junction temperature with an alternate temperature sensor (typically an RTD or thermistor) and applying a correcting voltage to the measured thermocouple voltage before scaling to temperature.The correction can be done electrically in hardware or mathematically in software. The software method is preferred as it is universal to all thermocouple types (provided the characteristics are known) and it allows for the correction of the small non-linearity over the reference temperature range.4. The low-level output from thermocouples (typically 50mV full scale) requires that care be taken to avoid electrical interference from motors, power cable, transformers and radio signal pickup. Twisting the thermocouple wire pair (say 1 twist per 10 cm) can greatly reduce magnetic field pickup. Using shielded cable or running wires in metal conduit can reduce electric field pickup. The measuring device should provide signal filtering, either in hardware or by software, with strong rejection of the line frequency (50/60 Hz) and its harmonics.5. The operating environment of the thermocouple needs to be considered. Exposure to oxidizing or reducing atmospheres at high temperature can significantly degrade some thermocouples. Thermocouples containing rhodium (B,R and S types) are not suitable under neutron radiation.The advantages and disadvantages of thermocouplesBecause of their physical characteristics, thermocouples are the preferred methodof temperature measurement in many applications. They can be very rugged, are immune to shock and vibration, are useful over a wide temperature range, are simple to manufactured, require no excitation power, there is no self heating and they can be made very small. No other temperature sensor provides this degree of versatility.Thermocouples are wonderful sensors to experiment with because of their robustness, wide temperature range and unique properties.On the down side, the thermocouple produces a relative low output signal that is non-linear. These characteristics require a sensitive and stable measuring device that is able provide reference junction compensation and linearization.Also the low signal level demands that a higher level of care be taken when installing to minimise potential noise sources.The measuring hardware requires good noise rejection capability. Ground loops can be a problem with non-isolated systems, unless the common mode range and rejection is adequate.Types of thermocoupleAbout 13 'standard' thermocouple types are commonly used. Eight have been given an internationally recognised letter type designators. The letter type designator refers to the emf table, not the composition of the metals - so any thermocouple that matches the emf table within the defined tolerances may receive that table's letter designator.Some of the non-recognised thermocouples may excel in particular niche applications and have gained a degree of acceptance for this reason, as well as due to effective marketing by the alloy manufacturer. Some of these have been given letter type designators by their manufacturers that have been partially accepted by industry.Each thermocouple type has characteristics that can be matched to applications. Industry generally prefers K and N types because of their suitability to high temperatures, while others often prefer the T type due to its sensitivity, low cost and ease of use.A table of standard thermocouple types is presented below. The table also showsthe temperature range for extension grade wire in brackets.Accuracy of thermocouplesThermocouples will function over a wide temperature range - from near absolute zero to their melting point, however they are normally only characterized over their stable range. Thermocouple accuracy is a difficult subject due to a range of factors. In principal and in practice a thermocouple can achieve excellent results (that is, significantly better than the above table indicates) if calibrated, used well below its nominal upper temperature limit and if protected from harsh atmospheres. At higher temperatures it is often better to use a heavier gauge of wire in order to maintain stability (Wire Gauge below).As mentioned previously, the temperature and voltage scales were redefined in 1990. The eight main thermocouple types - B, E, J, K, N, R, S and T - were re-characterised in 1993 to reflect the scale changes. (See: NIST Monograph 175 for details). The remaining types: C, D, G, L, M, P and U appear to have been informally re-characterised.Try the thermocouple calculator. It allows you the determine the temperature by knowing the measured voltage and the reference junction temperature.Thermocouple wire gradesThere are different grades of thermocouple wire. The principal divisions are between measurement grades and extension grades. The measurement grade has the highest purity and should be used where the temperature gradient is significant. The standard measurement grade (Class 2) is most commonly used. Special measurement grades (Class 1) are available with accuracy about twice the standard measurement grades.The extension thermocouple wire grades are designed for connecting the thermocouple to the measuring device. The extension wire may be of different metals to the measurement grade, but are chosen to have a matching response over a much reduced temperature range - typically -40°C to 120°C. The reason for using extension wire is reduced cost - they can be 20% to 30% of the cost of equivalent measurementgrades. Further cost savings are possible by using thinnergauge extension wire and a lower temperature rated insulation.Note: When temperatures within the extension wire's rating are being measured, it is OK to use the extension wire for the entire circuit. This is frequently done with T type extension wire, which is accurate over the -60 to 100°C range.Thermocouple wire gaugeAt high temperatures, thermocouple wire can under go irreversible changes in the form of modified crystal structure, selective migration of alloy components and chemical changes originating from the surface metal reacting to the surrounding environment. With some types, mechanical stress and cycling can also induce changes.Increasing the diameter of the wire where it is exposed to the high temperatures can reduce the impact of these effects.The following table can be used as a very approximate guide to wire gauge:At these higher temperatures, the thermocouple wire should be protected as much as possible from hostile gases. Reducing or oxidizing gases can corrode some thermocouple wire very quickly. Remember, the purity of the thermocouple wire is most important where the temperature gradients are greatest. It is with this part of the thermocouple wiring where the most care must be taken.Other sources of wire contamination include the mineral packing material and the protective metal sheath. Metallic vapour diffusion can be significant problem at high temperatures. Platinum wires should only be used inside a nonmetallic sheath, such as high-purity alumna.Neutron radiation (as in a nuclear reactor) can have significant permanent impact on the thermocouple calibration. This is due to the transformation of metals to different elements.High temperature measurement is very difficult in some situations. In preference, use non-contact methods. However this is not always possible, as the site of temperature measurement is not always visible to these types of sensors.Colour coding of thermocouple wireThe colour coding of thermocouple wire is something of a nightmare! There are at least seven different standards. There are some inconsistencies between standards, which seem to have been designed to confuse. For example the colour red in the USA standard is always used for the negative lead, while in German and Japanese standards it is always the positive lead. The British, French and International standards avoid the use of red entirely!Thermocouple mountingThere are four common ways in which thermocouples are mounted with in a stainless steel or Inconel sheath and electrically insulated with mineral oxides. Each of the methods has its advantages and disadvantages.Sealed and Isolated from Sheath: Good relatively trouble-free arrangement. The principal reason for not using this arrangement for all applications is its sluggish response time - the typical time constant is 75 secondsSealed and Grounded to Sheath: Can cause ground loops and other noise injection, but provides a reasonable time constant (40 seconds) and a sealed enclosure.Exposed Bead: Faster response time constant (typically 15 seconds), but lacks mechanical and chemical protection, and electrical isolation from material being measured. The porous insulating mineral oxides must be sealedExposed Fast Response: Fastest response time constant, typically 2 seconds but with fine gauge of junction wire the time constant can be 10-100 ms. In addition to problems of the exposed bead type, the protruding and light construction makes the thermocouple more prone to physical damage.Thermocouple compensation and linearizationAs mentioned above, it is possible to provide reference junction compensation in hardware or in software. The principal is the same in both cases: adding a correction voltage to the thermocouple output voltage, proportional to the reference junction temperature. To this end, the connection point of the thermocouple wires to the measuring device (i.e. where the thermocouple materials change to the copper of thecircuit electronics) must be monitored by a sensor. This area must be design to be isothermal, so that the sensor accurately tracks both reference junction temperatures.The hardware solution is simple but not always as easy to implement as one might expect.The circuit needs to be designed for a specific thermocouple type and hence lacks the flexibility of the software approach.The software compensation technique simplifies the hardware requirement, by eliminating the reference sensor amplifier and summing circuit (although a multiplexer may be required).The software algorithm to process the signals needs to be carefully written. A sample algorithm details the process.A good resource for thermocouple emf tables and coefficients is at the US Commerce Dept's NIST web site. It covers the B, E, J, K, N, R, S and T types.The thermocouple as a heat pumpThe thermocouple can function in reverse. If a current is passed through a thermocouple circuit, one junction will cool and the other warm. This is known as the Peltier Effect and is used in small cooling systems. The effect can be demonstrated by alternately passing a current through a thermocouple circuit and then quickly measuring the circuit's Seebeck voltage. This process has been used, with very fine thermocouple wire (0.025 mm with about a 10 mA current), to measure humidity by ensuring the cooled junction drops below the air's dew point. This causes condensation to form on the cooled junction. The junction is allowed to return to ambient, with the temperature curve showing an inflection at the dew point caused by the latent heat of vaporization.Measuring temperature differencesThermocouples are excellent for measuring temperatures differences, such as the wet bulb depression in measuring humidity. Sensitivity can be enhanced by constructing a thermopile - a number of thermocouple circuits in series.In the above example, the thermopile output is proportional to the temperaturedifference T1 - T2, with a sensitivity three times that of a single junction pair. In practice, thermopiles with two to hundreds of junctions are used in radiometers, heat flux sensors, flow sensors and humidity sensors. The thermocouple materials can be in wire form, but also printed or etched as foils and even electroplated.An excellent example of the thermopile is in the heat flux sensors manufactured by Hukseflux Thermal Sensors. Also see RdF Corp. and Exergen Corp.The thermocouple is unique in its ability to directly measure a temperature difference. Other sensor types require a pair of closely matched sensors to ensure tracking over the entire operational temperature range.The thermoelectric generatorWhile the Seebeck voltage is very small (in the order of 10-70μV/°C), if the circuit's electrical resistance is low (thick, short wires), then large currents are possible (e.g. many amperes). An efficiency trade-off of electrical resistance (as small as possible) and thermal resistance (as large as possible) between the junctions is the major issue. Generally, electrical and thermal resistances trend together with different materials. The output voltage can be increased by wiring as a thermopile.The thermoelectric generator has found its best-known application as the power source in some spacecraft. A radioactive material, such as plutonium, generates heat and cooling is provided by heat radiation into space. Such an atomic power source can reliably provide many tens of watts of power for years. The fact that atomic generators are highly radioactive prevents their wider application.译文：热电偶温度传感器热电偶的定义热电偶是最简单的传感器之一。

热电偶型温度计SS-CP-2280-US使用手册说明书

Specification Sheet SS-CP-2280-USFeaturesDesigned for people who perform tests and verifications of temperature sensing devices in the field. This instrument is ideal when time is a criti-cal factor and the highest accuracy is not a critical factor.Reduced size and weight are important considerations because the unit is able to fit into a tool box or instrument carrying case and can be used for sensors that are difficult to access.One-key-one-function user interface provides immediate access to set-ting the temperature and the auto-step timesaving function. There is no need for manipulation of sophisticated menus.The Stability indicator provides audible and visual prompts when the temperature is stable. This function also includes a 3 minute countdown before the stable condition.Stainless steel and rubber side panels make the instrument suitable for many years of faithful duty in an industrial environment.PRODUCT DESCRIPTIONHeats up by up to 100°C / 212°F per minute and completes a full dual-point test in less than 10 min-utes, including stability time; timesavings at your fingertips! The ETC- series is designed for field testing of temperature measure-ment devices.The small size and light weight make it a perfect instrument to verify sensors in difficult to reach places.All JOFRA ETC units have many of the same useful and timesaving features offered in the more advanced JOFRA dry-block series.Model ETC-seriesEasy Temperature CalibratorETC-400 R for infrared thermometersThe ETC-400 R is designed for optimum speed in connec-tion with calibration of infrared thermometers. The 36 mm target provides the optimum size for reliable calibrationof infrared thermometers in the process industry as it is designed for high accuracy and long-term stability while maintaining speed.With regard to the coating of the target it has been espe-cially designed for space technology applications, which secure long time performance under high temperature influence. In combination with the shape of the target it ensures the emissivity of 0.96.If higher accuracy is required, and for recalibration, a 3 mm external JOFRA STS reference probe can be placed under the surface of the target.Find ordering information for the STS-103 B reference sensor at page 7.Super fast heating - ETC-400 A dry-blockThe ETC-400 A is designed for optimum speed. The heat-ing block is built around a highly efficient heating element. The insertion holes for the temperature device undertest are located around this element. To reduce mass and increase effectiveness, there is no removable inser-tion tube; the holes are drilled directly into the block. The minimal mass offers an extremely fast heating and cooling time. The different layouts also make it possible to use an external JOFRA STS reference probe during the calibra-tion. Choose the combination of holes that best suits your needs from our various design combinations.If your application requires a dry-block that can handle large sensors or more than one sensor at a time, we offer several other JOFRA dry-block calibrators that can meet your needs.Cooling and heating - ETC-125 A dry-blockThe ETC-125 A is a simple yet effective tool for verify-ing temperature instruments that also require references below ambient temperatures: e.g. air-conditioning and cold counters. The predrilled holes allow the use of an insertion tube in the largest bore. This increases the flex-ibility to match many sensor-under-test sizes.Easy-to-use, intuitive operationAll instrument controls are accessed directly from the front panel. The main functions on the ETC series are designed with one-key-one-function logic. This means that there are no difficult multiple keystrokes to remember to access pri-mary functions. The easy-to-read, backlit display features dedicated icons, which help in identifying instrument con-ditions and operational steps.Set temperatureThe ’’Up’’ and ’’Down’’ arrow keys allow the user to set the exact temperature desired with a resolution of 0.1°C or °F.Instrument setupsThe ETC-series stores the complete instrument setup, including: engineering units, stability criteria, resolution, auto-step settings, and maximum temperature.Stability indicatorThe bold checkmark on the display indicates that the calibrator has reached the desired set temperature and is stable. The operator may change the stability criteria and establish a greater level of confidence in the calibration results as desired. A convenient countdown timer is acti-vated three minutes before the unit reaches stability. Thisprompts you to be prepared to record results.2 JOFRA IR-LAB software for the ETC-400 RAs an extra feature the ETC-400 R will be delivered with a small mathematical program, which will constitute a powerful tool together with the calibrator. The program enables you to calculate at which temperatures you need to calibrate, if your IR thermometer is either locked to a fixed emission factor or if you just want to calibrate your thermometer at a certain emission factor. The program fa-cilitates the whole issue of correcting settings of emission factors and temperatures.The calibration surface of the JOFRA ETC-400 R IR calibrator has an emission factor of 0,96. If your IR-ther-mometer is using a different emission factor than 0.96, the result will be a faulty temperature reading on your IR thermometer. However if your IR thermometer is using an emission factor of 0.95 or 0.98 – a helpfull diagram is part of the standard delivery.Example: Your thermometer is locked to an emission factor of 0,98 and you have set the JOFRA ETC-400 R to 300°C. The diagram indicates that 3,9°C must be subtracted from the calibrator temperature, to obtain the “true” IR thermometer reading (296,1°C).If you are working with IR thermometers where the emis-sion factor is different than 0.95, 0.96 or 0.98, or other parameters differ from “standard”, use the PC program JOFRA IR-Lab. The JOFRA IR-Lab program allows you to type in various emission factors, in order to get a “true” temperature readout on your thermometer or the other way around - what is the true surface temperature of the calibrator. But the IR-Lab will do more than that; it allows you to calculate “true” temperatures in simulated sur-roundings that approximate your actual test environments.Calibration of up to 24 sensors with JOFRA ASMUsing the JOFRA ETC series together with the ASMAdvanced Signal Multi-scanner offers a great time-saving automatic solution to calibrate multiple temperature sen-sors at the same time.The ASM series is an eight channel scanner controlled by JOFRACAL software on a PC. Up to 3 ASM units can be stacked to calibrate up to 24 sensors at the same time. It can handle signals from 2-, 3- and 4 wire RTD’s, TC’s, transmitters, thermisters, temperature switches and volt-age.Please also see more in specification sheet SS-CP-2360, which can be found at www.jofra.comAuto-steppingThis feature saves time. The operator may stay in the con-trol room, or another remote location, monitoring the out-put from the sensor-under-test while the ETC- series cali-brator is placed in the process and automatically changes the temperature using a programmed step value and rate. Up to 9 different temperature steps may be programmed, including the hold time for each step. This feature is also ideal for burning-in new sensors prior to installation; this minimizes initial drift and allows for initial testing. It is also useful for testing temperature data loggers.Maximum temperatureFrom the setup menu, you can select a lower maximum tem-perature limit for the calibrator. This function prevents damage to the sensor-under-test caused by the application of exces-sive temperatures.Re-calibration/adjustments made easyThe ETC- series has a very easy and straightforward pro-cedure for re-calibration/adjustment. There is no need for a screwdriver or PC software. The only thing you need is a reliable reference thermometer. Place the probe in thecalibrator and follow the instructions on the display.Use the ETC calibrator with JOFRACAL calibration software 3122832 Cleaning Brushes - 4 mm - Package of 3 pcs 60F174 Cleaning Brushes - 6 mm - Package of 3 pcs 122822 Cleaning Brushes - 8 mm - Package of 3 pcs 125002 Edgeport Converter with 4 pcs of RS232 ports 124094Carrying Case for ETC Series1) The ETC-400 R is delivered with a carrying case as standard because it is important to keep dust away from the surface of the target on the ETC-400 R. The reason being that a clean surface is important to keep the emissivity and thereby the accuracy. The car-rying case is optional for ETC-400 A and ETC-125 A.STANDARD DELIVERYJOFRA ETC dry-block calibratorTraceable calibration certificate - temperatureperformanceJOFRACAL calibration software User and reference manual Mains power cable Shoulder strap RS232 cable1 × predrilled insertion tube (ETC-125 A only)Tool for insertion tubes (ETC-125 A only)Carrying case (ETC-400 R only) 1)JOFRA IR-LAB calibration software (ETC-400 R only)Emissivity table (ETC-400 R only)••••••••••••ACCESSORIESCarrying case (Optional for ETC-125 / 400 A) - 124094The optional protective carrying case ensures safe trans-portation and storage of the instrument and all associated equipment.JOFRACAL CALIBRATION SOFTWAREJOFRACAL calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermoswithes, pressure gauges and pressure switches. JOFRACAL can be used with JOFRA DPC-500, APC, CPC and IPI pres-sure calibrators, all JOFRA temperature calibrators, as well as JOFRA AMC900, ASC300 multi signal calibrator and ASM-800 signal multi scanner.JOFRACAL calibration software may also be used for manual calibrations, as it can be set up to accept manual entry of calibration data together with other liquid baths, ice points or dry-block heat sources.The calibration data collected may be stored on a PC for later recall or analysis. The calibrator stores the calibration procedure and may be taken out to the process site with-out using a personal computer.Once all calibrations are completed, the data may be uploaded to the JOFRACAL calibration software for post-processing and printing of certificates. The calibration data collected may be stored on the personal computer for later recall or analysis.The JOFRACAL temperature calibration software may bedonwloaded from our web-page .Please also see more about JOFRACAL calibration software in specification sheet SS-CP-2510, which can be found atJOFRACAL softwareMinimum hardware requirements for JOFRACAL calibra-tion software.INTEL TM 486 processor(PENTIUM TM 800 MHz recommended)32 MB RAM (64 MB recommended)80 MB free disk space on hard disk prior to installation Standard VGA (800 x 600, 16 colors) compatible screen (1024 x 786, 256 colors recommended)CD-ROM drive for installation of the program 1 free RS232 serial port••••••••4 *******************************°C/73°F ETC-125 A Maximum ........................................................125°C / 257°F *********************°C/32°F...........-18°C / -0°F **********************°C/73°F............-10°C/14°F **********************°C/104°F...........6°C / 43°F ETC-400 A ......................28 to 400°C / 82 to 752°F@ 23°C ETC-400 R ......................28 to 400°C / 82 to 752°F@ 23°C Resolution (user-selectable)Selectable .............................................................1º or 0.1ºHeating timeETC-125 A-10 to 23°C / 14 to 73°F .........................................3 minutes 23 to 100°C / 73 to 212°F ....................................11 minutes 100 to 125°C / 212 to 257°F ..................................7 minutes ETC-400 A / R28 to 200°C / 82 to 392°F .....................................2 minutes 200 to 400°C / 392 to 752°F .................................3 minutes Cooling timeETC-125 A125 to 100°C / 257 to 212°F .................................1 minute 100 to 0°C / 212 to 32°F ......................................17 minutes 0 to -10°C / 32 to 14°F .........................................14 minutes ETC-400 A400 to 200°C / 752 to 392°F .................................6 minutes 200 to 50°C / 392 to 122°F ..................................15 minutes ETC-400 R400 to 200°C / 752 to 392°F .................................9 minutes 200 to 50°C / 392 to 122°F ..................................24 minutes StabilityETC-125 A ..............................................±0.05°C / +0.09°F ETC-400 A .............................................±0.15°C / +0.27°F ETC-400 R ...............................................±0.3°C / ±0.54°FMeasured after the stability indicator has been on for 10 minutes.

They must know how to recognize hazardous and potentially hazardous conditions, and know how to avoid them. The consequences ofunskilled, improper, or careless operation of the equipment can be serious. Every operator or service person must read and thoroughly understand operation/maintenance manuals and any additional information provided by Varian. All warning and cautions must be read carefully and strictly observed. Consult local, state, and national agenciesregarding specific requirements and regulations. Address any safety, operation, and/or maintenance questions to your nearest Varian office.Solvents WARNINGThe mechanical components of leak detectors may be cleaned with one of the recommended solvents. When heated, sprayed, or exposed to high-temperature equipment, these solvents become flammable and explosive, causing seriousinjury or death. Do not use these solvents near a high-temperature source. Ventilate the working area with a blower and work in a large, well-ventilated room.Solvents are irritants, narcotics, depressants and/or carcinogens. Their inhalation and/or ingestion may produce serious side effects. Prolonged or continued contact with the skin results in absorption through the skin and moderate toxicity. Always ensure that cleaning operations are carried out in large, well-ventilated rooms, and wear eye shields, gloves, and protective clothing.Due to the effective cleaning nature of VacuSolv solvent and its residue-free properties, Varian’ Component and Spectrometer Cleaning Kit (Part Number 670029096), used in accordance with the kit instructions, is recommended for cleaning spectrometer components. The kit can also be used for fine cleaning of other parts in the leak detector’s vacuum system such as valves and fittings. No rinsing steps or high-temperature drying is required following cleaning withVacuSolv. Although appropriate precautions are advised, VacuSolv is compatible with most materials and does not contain toxic chemicals or CFCs(chlorofluorocarbons). Other acceptable solvents are isopropyl alcohol (IPA) or Dow Corning ® OS-20.To clean the leak detector plastic enclosure, the LCD display and Front Panel buttons, use only a soft cloth slightly dampened with water or a mild soap.Do NOT use excess water or cleaning solvents of any kind.Avoid splashing any cleaning solvents into the unit through the ventilation openings or Front Panel buttons. Wipe the surface with a dry lint-free cloth.Vacuum Equipment and CleanlinessCleanliness is vital when servicing the leak detector or any vacuum equipment. There are some techniques that are more important in leak detector servicing than in general vacuum work:CAUTIONWear non-powdered, ESD-safe Nitride or equivalent gloves to prevent skin oils from getting on spectrometer internal components.Document No.RevisionThermocouple Gauge and Octal Cable Replacement for VS Series Leak DetectorsPage 3 of 8O-ring CareWhen removing, checking or replacing O-rings, keep in mind the following:NOTEVarian recommends replacing all O-rings during routine maintenance or during any maintenance procedure requiring that O-rings be removed.CAUTIONRemove O-rings carefully with your fingers. Do not use metal tools for this task; this prevents scratching of any sealing surfaces.•Wipe all O-rings clean with a lint-free cloth before installation to ensure that no foreign matter is present to impair the seal.•Do not use grease or any other substance on O-rings that will come in contact with the vacuum surfaces.•Do not use alcohol, methanol or other solvents on O-rings. Doing so causes deterioration and reduces their ability to hold a vacuum.•Varian does not recommend the use of vacuum grease. If applicable, apply a small amount of Apiezon ®L grease and wipe the O-rings shiny dry.Metal Seal Care CAUTIONMetal Seals must be replaced any time a spectrometer is opened. All fasteners must be installed and torqued per assembly procedure specifications. Remove Metal Seals carefully with your fingers or a soft tool. Metal tools scratch sealing surfaces.•Metal Seals are supplied in pre-cleaned condition. No cleaning is required. If necessary, Metal Seals can be cleaned using the recommended solvents. Wipe Metal Seals clean with a lint-free cloth before installation to ensure that no for-eign matter impairs the seal.•Do not use grease or any other substance on Metal Seals that will come in con-tact with the spectrometer.Spectrometer CAUTIONStore the Ion Source/Preamplifier sub-assembly in a cool, dry area in a tightly sealed, ESD protected container. Wear non-powdered, ESD-safe Nitride orequivalent gloves when handling the spectrometer. Wash hands thoroughly after handling the spectrometer filaments and especially before smoking or eating.The spectrometer and PCB’s are static sensitive devices. Wear a grounding strap when performing any maintenance on these units and especially when performing maintenance of static sensitive parts.CAUTIONThe spectrometer operates at a very high vacuum produced by the high vacuum turbomolecular pump. Service of the spectrometer requires that this vacuum be vented to the atmosphere.Equipment Required•Extended Length M5 Allen Wrench•Metric Allen Wrench SetInstallation ProcedureFor clarity, some items have been omitted from views.Figure 1: Rear and Front Cover ScrewsWARNING Disconnect power from the unit before performing any maintenance procedure that requires physically disconnecting any part of the system.1.Turn off the power switch located on the back of the unit and unplug.2.Wait 30 seconds for the high voltage to dissipate.ing an extended length M5 Allen wrench, remove the four screws holding the rear plastic cover (Figure 1: Rearand Front Cover Screws) and detach the rear plastic cover from the unit.4.Remove the four screws holding the front plastic cover and detach the cover from the unit.

ThermocoupleEnglish Instruction ManualIntroductionThe thermocouple is a device used to measure temperature by converting thermal energy into electrical energy. It operates based on the thermoelectric effect, where a voltage is generated when two different metals are joined and heated.Operating PrinciplesThe thermocouple works on the principle of the Seebeck effect. When two dissimilar metals are joined and heated, a voltage is produced at the junction due to the difference in the electrons' ability to move through the metals. This voltage can be measured and used to determine temperature.ComponentsA thermocouple typically consists of two wires made of different metals, joined together at one end. The other ends of the wires are connected to a measuring instrument, such as a voltmeter or temperature indicator.Types of ThermocouplesThere are several types of thermocouples, classified based on the materials used for the wires. Common types include Type J, Type K, Type T, and Type E. Each type has its own temperature range and accuracy.Installation and UsageSelect the appropriate type of thermocouple based on the temperature range and accuracy requirements.Ensure that the thermocouple is properly inserted into the measurement point, ensuring good thermal contact.Connect the free ends of the thermocouple wires to the measuring instrument.Power on the measuring instrument and follow its instructions to read the temperature.Maintenance and TroubleshootingRegularly inspect the thermocouple for damage or corrosion.Ensure that the thermocouple is properly inserted and secured in the measurement point.If the measured temperature is inconsistent or unstable, check for any loose connections or damaged wires.Safety PrecautionsHandle the thermocouple with care to avoid bending or breaking the wires.Do not expose the thermocouple to temperatures exceeding its rated range.Disconnect the thermocouple from the measuring instrument before performing any maintenance or repairs.DisposalDispose of the thermocouple in accordance with local regulations and guidelines for the disposal of electronic waste.WarrantyThis thermocouple is warranted to be free from defects in materials and workmanship for a period of one year from the date of purchase. If any defect is found, please contact our customer service for assistance.介绍热电偶是一种通过将热能转换为电能来测量温度的装置。

As sensor for temperature measuring and regulation, industrial-purpose thermal resistance is usually connected with display meter and other meters to directly measuretemperature of liquid, vapor, gas and solid surface ranging from -200℃to 500℃.2、工作原理Operation Theory12.1热电偶工作原理Operation Theory of Thermocouple热电偶工作原理是基于两种不同成分的导体两端连接成回路，如两连接端温度不同，则在回路内产生热电流的物理现象。

热电偶由两根不同导线(热电极)A和B组成，它们的一端T1是互相焊接的，形成热电偶的测量端T1(也称工作端)。

将它插入待测温度的介质中；而热电偶的另一端T0(参比端或自由端)则与显示仪表相连，如果热电偶的测量端与参比端存在温度差，则显示仪表将指出热电偶产生的热电动势。

热电偶的热电动势随着测量端温度的升高而增大，它的大小只与热电偶的材料和热电偶两端的温度有关，而与热电级的长度、直径无关。

Thermocouple is based on physical phenomenon that two conductor of different materials is connected to form return circuit, when temperature on both contact is different,it results in thermoelectric potential in return circuit.2.2热电阻工作原理Operation Theory of Thermal Resistance热电阻是利用金属导体或半导体有温度变化时本身电阻也随着发生变化的特性来测量温度的，热电阻的受热部分(感温元件)是用细金属丝均匀地绕在绝缘材料作成的骨架上，当被测介质有温度梯度时，则所测得的温度是感温元件所在范围内介质层的平均温度。

制造热电阻的材料应具有以下特点：大的温度系数，大的电阻率，稳定的化学物理性能和良好的复现性等。

在现有的各种纯金属中，铂、铜和镍是制造热电阻的最合适的材料。

其中铂因具有易于提纯，在氧化性介质中具有高的稳定性以及良好的复现性等显著的优点，而成为制造热电阻的理想材料。
