Electrical connection of the torque transducer• Cable type: at least 12 conductors, e.g. LIYCY12 x 0.14• Max. cable length: 15 m43.1 Connector pin assignmentsDescription of interface for Type, art.-no.: 7203Angle outputs: open collector outputs with internal 10k Ωpull-up to +Vop Built in connector: Binder Series 680, type 09-0331-80-12 or equivalent Cable diagram with plugs on both sides5Top view of connector on transducer3.1.1Signals, angle outputs3.2Laying of the output signal cables-Note on safety-• Do not lay together with control lines or lines carrying a high current.• Do not lay close to strong electromagnetic fields, e.g. those of transformers,welding equipment, contactors, motors, etc.• If the above is unavoidable, the cables must be laid in grounded heavygage steel conduit.• At the transducer, lay the cables in a sling in order to prevent vibration-induced damage to them.3.3Placement of conducters in cableIn order to prevent the measurement signal being distorted by the angle pulses,the corresponding conductors should be separated within the cable.6The cable length has virtually no influence on the measurement signal, but in the case of the angle outputs the external pull-up resistances must be properly adjusted.74.Mechanical installation of the torque transducerTransducer with fixed stator:2 holes are provided in the transducer housing for this purpose.• Use displaceable couplings as both shaft ends that are capable of accommodating angular, radial and axial misalignment.• Good results have been obtained with miniature couplings stiff against torsion such as those described in data sheet 8303.At torques of 50 Nm or greater, it is also possible to install the transducer without fixed stator:• In this case, use flexible couplings at both ends.Caution:during installation no impermissibly high torques may beallowed to arise between the two ends of the torque transducer shaft.4.1Suggestions for installationTransducer with fixed stator and couplings able to accommodate angular, radial and axial misalignment at both ends.8This type of installation is possible at torques of 50 Nm and greater.5.Mechanical calibrationTo perform this, a calibration setup with lever arm and weights is needed tocreate a torque.Steps for calibration:a)Apply the rated torque to the transducer, then remove the load again.b)Precisely adjust the transducer to the zero point.c) Apply a known torque to the transducer.d) Set the indicator to the proper value.Recording of a calibration curve:a) Calibrate the transducer as described above.b) Progressively apply greater torques to the transducer in steps of 1/10 up tothe full rated torque. Then gradually remove the torque in the same way. Ateach step, wait at least 30 seconds for the torque reading to stabilize, and thenrecord.95.1A simple calibrating setup5.2Sample calculation of lever arm length10eg. m = 1 kg. Mt = 10 NmL =10Nm sec 21 kg _ 9.80665= 1,0197 m5.3Electrical calibrationA calibration control facility is integrated in the transducer to permit electrical calibration.Procedure for electrical calibration:• Remove all mechanical loads from the transducer (no torque).• Apply the calibration voltage Vc to pin K referenced to pin E.• An output signal corresponding to the rated torque will be emitted.6.Maintenance• Type IE transducers require virtually no maintenance.• The service life expectancy of the bearings within the rated temperature range is approx. 20,000 hours.• The service life expectancy of the bearing within the operating temperature range is approx. 10,000 hours.• The bearings can only be replaced in the factory.• For high-precision applications: recalibrate the transducer once annually (calibration at the factory or using an appropriate calibration setup).• Once a month, check the cable connectors to make sure that they are securely seated.• Check the cables for damage once a month.117.Troubleshooting guide for transducer shaft12ProblemProbable causesRemedial actionShaft does not rotate Bearings are defective due to:freelya) Torsional or flexional vibrations b) Excessive axial or radial loads Return to factoryc) Old or soiled bearings d) Bent shaft Zero point displacement Rotational vibration Readjust zero point on ≤2 %Shock forcesinstrument amplifier Zero offset between 2%Transducer has been overloaded The zero point can be and 5% of range Shock forcesrecalibrated once at Rotational vibrationthe instrument amplifier Transducer has Transducer has been overloaded hysteresis between by changing loads or rotational Return to factoryclockwise and counter-Rotation vibrationclockwise torqueNOTES: 13WARRANTY/DISCLAIMEROMEGA ENGINEERING, INC. warrants this unit to be free of defects in materials and workmanship for a period of 13 months from date of purchase.

Printed in U.S.A.SECTION IIIOPERATIONPRINCIPLE OF OPERATIONThe Model PX831 and PX832 PressureTransmitter series are designed to continuouslymeasure process pressure. The heart of thetransmitter is a silicon piezoresistive sensing chip.This miniature microetched semiconductor givesan output proportional to the applied pressure.This chip is isolated from the process media by astainless steel diaphragm. A silicone oil or otherspecified fill fluid is used to transmit the processpressure to the sensor.A surface mount amplifier board, enclosed in asealed chamber, is used to convert the millivoltsignal from the sensor to a calibrated transmitteroutput. Transmitter electronics are completelysurge protected.Each transmitter is tested over both pressure andtemperature ranges. A thick film compensatorcircuit is used to bring the output of the sensorinto specification. After compensation, everytransmitter is tested a second time for pressure andtemperature effects to ensure that it meetsperformance specifications.3-1OPERATION2-2CONTENTSWARRANTY .............................................................................................................coverINTRODUCTION ...........................................................................................................ii SAFETY SUMMARY ..

Fixed range, all stainless steel transmitters, are designed to continuously measure process pressure for years with stable performance in even the toughest environmental and media conditions. The silicon piezoresistive sensing element consists of four ion implanted strain gauges forming a Wheatstone bridge circuit which will vary its resistance when subjected to process pressure. The Model PX831 and PX832 meet FM & CSA approval for explosion-proof rating in hazardous locations. They also meet NACE standards for offshore applications.The small size and light weight of these transmitters eliminates the need for complicated mountinghardware and mechanical supports, thereby reducing installation time substantially. The inline connection permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation. Its profile allows for mounting in places too tight for other transmitters.With all 316 stainless steel welded construction, the Model PX831 and PX832 are compatible with corrosive media and hazardous environments. The transmitters are weather proof and capable of withstanding direct spray.SPECIFICATIONSFUNCTIONAL SPECIFICATIONS Service: Liquid, Gas or Vapor Pressure Range Limits:-14.7 to 5000 PSI (-1.0 to 345 BAR) Input (Power Supply) / Output:PX831 = 12-30 VDC / 4-20 mADC, *Limited to 30 mADC PX832 = 8-14 VDC / 1-5 VDC OffsetPX831 = 4.0 mA ±2% Span PX832 = 1.0 VDC ±2% Span SpanPX831 = 16.0 mA ±l % Span PX832 = 4.0 VDC ±1% SpanLoop Resistance: 900 ohms max @ 30 VDC (PX831Only)Temperature RANGE:Ambient Operating: -400F to 1400F (-400C to 600C) Process Interface: -400F to 2120F (-400C to 1000C) Storage: –400F to 2120F (-400C to 1000C) Overpressure: 300% Span Humidity Limits: 0-100%RHPERFORMANCE SPECIFICATIONSAccuracy: ±0.30% of Span (BFSL) including linearity, Hysteresis and repeatability at 250C and 12 VDC supply voltageStability: ±0.50 Span for six monthsTemperature Effect: (includes zero & span) Compensated: -20 to 1400F (-29 to 600C) ±2.0% / 500F (280C)Vibration Effect: ±0.1% for 3g to 200 HzPHYSICAL SPECIFICATONS Materials of ConstructionProcess Wetted Parts: 316L SS Non Wetted Parts: 316 SS Fill Fluid: Silicone (DC200)Process Connection: 1/2" NPT-FemaleElectrical Connection: 3/4" NPT-Female / Cable Weight 0.83 lb.

OMEGA is constantly pursuing certification of its products to the European New Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.The information contained in this document is believed to be correct but OMEGA Engineering, Inc. accepts no liabili-ty for any errors it contains, and reserves the right to alter specifications without notice.WARNING: These products are not designed for use in, and should not be used for, patient connected applications.2IntroductionAll OMEGA force gauges are easily mounted any of the test stands. The combination of gauge and stand will create a high-precision, compact load tester for a wide range of applications. In addition, any model can be converted to any other model by following procedures in this manual.Model DFG-TS-C , the factory standard configuration, is for a compression application.When you pull the lever arm down and toward you, the gauge will also come down and compress.Model DFG-TS-T is config-ured for tension. When you pull the lever arm down and toward you, the gauge will move up and create tension.Mounting the Gauge1.Mount digital gauges to the stand using the screws supplied with the stand. (FIG.2)When mounting mechanical gauges to the stand, hold the gauge firmly and unscrew the 4 screws in back, making sure the case does not separate.

Any num-ber of decades from one to eleven is available in a choice of accuracies.The Omega DB decade box is a precision resis-tance source with excellent characteristics of stabil-ity, temperature coefficient, power coefficient, and frequency response.The Omega DB Series employs very-low-resistance switches with silver alloy contacts. A special design keeps zero resistance to less than 1 mΩ per decade. Self cleaning keeps the silver contacts from becom-ing tarnished when unused, or when only low cur-rents are passed through them. This is most often the case when only minute test currents are drawn by digital multimeters or other test instruments. Contact resistance is stable and remains low and repeatable. High-quality gold-plated tellurium-copper binding posts serve to minimize the thermal emf effects which would artificially reflect a change in dc resistance measure-ments. All other conductors within the instrument, as well as the solder employed, contain no metals or junc-tions that could contribute to thermal emf problems.The standard models offer a choice of one through eleven decades. The panels are clearly labeled show-ing the step size and maximum voltage and current limitations for each decade.With a resolution as low as 1 mΩ and a maximum available resistance of over 111 MΩ, the Omega DB series may be used for exacting precision measure-ment applications requiring high accuracy, good sta-bility, and low zero-resistance. They can be used as components of dc and ac bridges, for calibration, as transfer standards, and as RTD simulators.The Omega DB Series may be rack-mounted to serve as components in measurement and control sys-tems.Figure 1.1. DBX Series High Accuracy Decade BoxChapter 2SPECIFICATIONSFor convenience to the user, the pertinent specifications are given in an OPERATING GUIDE affixed to the case of the instrument. Figure 2.1 shows a typical example.SPECIFICATIONSSingle Decade DBX UnitSINGLE DECADE UNITSORDERING INFORMATIONSingle-decade units are available withresistance as low as 1 m Ω per step toas high as 10 M Ω per step. These unitssatisfy many system applications re-quiring only a single decade whilemaintaining all the quality features ofthe DB series.Each decade is enclosed in an alumi-num case which can serve as a shield.It may be panel mounted and inte-grated with additional units to form potentiometer circuits or other con-figurations.Each unit consists of low-inductance resistors in series, with a high-perfor-mance solid-silver-alloy-contact switch.* For less exacting applications, more economical tolerances are available:- For 0.02% accuracy substitute DBQ in part number in lieu of DBX- For 0.05% accuracy substitute DBA in part number in lieu of DBX- For 0.1% accuracy substitute DBB in part number in lieu of DBX OPTIONS - RM Rack mountable case for standard 19" rack - K Kelvin type 4-terminal binding posts - RO Rear output binding postsChapter 3OPERATION3.2.2 Electrical Considerations In order to make proper use of the full performance capabilities of the DBX unit, especially if low resis-tance or low-resistance increments are important,care must be taken in connecting to the terminals of the decade box.In particular, in order to keep contact resistance to a minimum, the most substantial and secure connec-tion to the binding posts should be made. They ac-cept banana plugs, telephone tips, spade lugs, alli-gator clips, and bare wire. The largest or heaviest mating connection should be made, and, where ap-plicable, the binding posts should be securely tight-ened.These considerations may be relaxed whenever single milliohms are considered significant for the task being performed.3.2.3Four-Wire Kelvin Lead Connections Whenever possible, 4-wire Kelvin leads, the ideal connection, should be employed. Such a connec-tion minimizes the effects of contact resistance and approaches ideal performance.If the four terminals are available as clamps similar to alligator clips, they may be connected to the necks of the binding posts. If the four terminals are avail-able separately, the optimal connection is shown in Figure 3.1, where the current leads are introduced into the top of the binding posts, and the voltage leads at the necks.3.1 Initial Inspection and SetupThis instrument was carefully inspected before ship-ment. It should be in proper electrical and mechanical order upon receipt.An OPERATING GUIDE is attached to the case of the instrument to provide ready reference to speci-fications.3.2 Connection3.2.1General ConsiderationsThe DBX Series Decade unit provides three termi-nals labeled H (high), L (low), and G (ground). The H and L terminals are connected to the ends of the resistance being set; the G terminal is connected to the case. The G terminal may be used as a guard or shield terminal. It may also be connected (using a shorting link) to either terminal to allow two-termi-nal as opposed to three-terminal measurements.In order to make the most stable measurements,determine which is the more sensitive of the two user leads, i.e. the one going into a higher impedance.This lead should be connected to the more protected one of the two DBX terminals. That would either be the DBX terminal that is shorted to the case, or the LOW DBX terminal whenever neither is con-nected to the case.3.2.4 Thermal emf ConsiderationsThe highest-quality low-ernf components are used in the DBX Series. There nevertheless may be some minute thermal emf generated at the test leads where they contact the gold banana jacks.This emf will not reflect itself if an ac measurement instrument is employed. It will also be eliminated if a meter with so called “True Ohm” capability is used. Otherwise it may represent itself as a false compo-nent of the dc resistance measurement.3.3 Dial SettingWhenever the dials are used in positions 0-9, the resulting resistance is simply read directly. Both the decimal point and the steps are clearly marked on the panel.For additional flexibility and range, each decade pro-vides a “10” position setting. This “10” position on any one decade equals the “1” position on the next higher decade. It adds about 11% to the nominal total decade resistance.To determine the resistance obtained when one or more “10” settings are used, simply add “1” to the next higher decade. For example, a setting of3-6-10-0-10 Ω becomes:330000660001010000001010____________________________ TOT37010and a setting of 10-10-10-l0-10.10 Ωbecomes:10100000.01010000.0101000.010100.01010.0.10 1.0________________________________ TOT11111 1.0 3.4 Environmental ConditionsFor optimal accuracy, the decade box should be used in an environment of 23o C. It should be allowed to stabilize at that temperature after any significant tem-perature variation.Humidity should be maintained at laboratory condi-tions. This is especially important if high resistances are involved.Figure 3.1 Optimal 4-Wire Kelvin Lead ConnectionChapter 4 MAINTENANCE4.1Verification of Performance4.1.1Calibration IntervalThe DB Series instruments should be verified for performance at a calibration interval of twelve (12) months. This procedure may be carried out by the user if a calibration capability is available, by Omega, or by a certified calibration laboratory.If the user should choose to perform this procedure, then the considerations below should be observed.4.1.2General ConsiderationsIt is important, whenever testing the DBX Series Decade Units, to be very aware of the capabilities and limitations of the test instruments used. A resis-tance bridge may be employed, and there are di-rect-reading resistance meters or digital multimeters available that can verify the accuracy of these units, especially when used in conjunction with standards that can serve to confirm or improve the accuracy of the testing instrumentSuch test instruments must be significantly more ac-curate than ±(l00ppm+2 mΩ) for all applicable ranges, allowing for a band of uncertainty of the in-strument itself. A number of commercial bridges and meters exist that can perform this task; consult Omega.It is important to allow both the testing instrument and the DBX Substituter to stabilize for a number of hours at the nominal operating temperature of 23O C, and at nominal laboratory conditions of hu-midity. There should be no temperature gradients across the unit under test.Substantial Kelvin type 4-wire test terminals should be used to obtain accurate low-resistance readings. It is convenient, once the zero resistance has been determined, to subtract it from the remaining mea-surements. This can be automatically done in many instruments which have an offset subtraction capa-bility.4.1.3 Procedure1.Confirm the zero resistance of the unit.2.Determine the allowable upper and lowerlimits for each resistance setting of each decade following the specified accuracy. For theDBX series, these limits for any resistance“R” are [R±(0.0001 R + 2 mΩ)]. For the A,B, or Q series, see specifications.3.Confirm that the resistances fall within theselimits after subtraction of the zero resistance.4.If any resistances fall outside these limits, theassociated switch assembly may requirereplacement.4.2 SchematicRefer to Figure 4.1 for a schematic of the DB de-cade unit.8MAINTENANCEFigure 4.1.

General DescriptionIntroductionSCR Power Controllers are designed to regulate ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note: They are not designed to drive transformers, coils or other inductive-type loads.)The controller accepts an input signal, such as 4-20 mAdc from some signal conditioning device, e.g., a temperature controller. For most processes, the combination of a temperature controller and SCR power controller will provide very accurate, automatic temperature control. For manual operation, a manual control option with a remote potentiometer is available.General SpecificationsInputs:4-20 mAdc standard, or as ordered (seeserial number) minimum voltagerequirements 10 Vdc; all inputselectrically isolated via optical couplingSupply Voltage:110/120; 208/240; 440/480, 575/600Vac, or as ordered (Phase connectionnot critical on 3-phase units)Frequency:50/60 HzAmbient T emperature:30o to 122o F for listed power ratings Cooling:ConvectionProtection:Sub-cycle, current-limiting fuse; transientvoltage suppresionLoad Resistive, 1- or 3-phase - 3-wire Wye or Delta All specifications subject to change.1234567Figure 4a. Wiring scheme for Series 19Z.Figure 4b. Wiring scheme for Series 39Z.3.21 Zero-Cross Zero-cross mode power controllers may only be used with constant resistance heating elements, such as Nichrome. They are NOT intended for high-inrush loads. Depending on the type of element used, you can oversize the load controller.3.22 Phase-AnglePhase-Angle fired power controllers may be used with high-inrush loads if the "soft-start" option is installed.Figure 5a. Wiring scheme for Series 19P.Figure 5b. Wiring scheme for Series 39P .Section 4. OperationSeries19/394.1 Series 19Z/39ZThe Series 19Z and 39Z power controllers are designed to control ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note:They are NOT intended to drive transformer coupled or inductive loads.) The controllers consist of power semiconductors (SCRs), properly sized heat sinks, and trigger circuitry. These controllers accept a control signal (e.g., 4-20 mAdc) from a signal conditioning device, such as a temperature controller. The “Z” suffix designates the controller as operating in the Zero Cross, Zero Voltage Switched, or Zero Burst firing mode.A patented trigger circuit turns on the SCRs as close as possible to the point at which the ac sine wave crosses through zero. In effect, this turns the line voltage on and off in full cycles. With an input of 4-20 mA , the output will be FULL OFF below 4 mA and FULL ON at 20 mA. Proportioning action is obtained by varying the number of cycles ON to the number of cycles OFF. The resulting output power is integrated by the heaters to produce smoothly proportional heating that varies directly with the input signal.4.2 Series 19P/39PThe Series 19P and 39P power controllers are designed to control ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note: They are NOT designed to drive transformer-coupled loads.) The controllers consist of power semiconductors (SCRs), properly sized heat sinks, and trigger circuitry.These controllers accept a control signal (e.g., 4-20 mAdc) from a signal conditioning device, such as a temperature controller.The “P” Suffix designates the controller as operating in the Phase-Angle firing mode. Providing full proportional control, SCRs are turned ON during each 1/2 cycle at apoint (phase angle) of the ac sine wave, remaining ON for the rest of the1/2 cycle. By varying the phase angle setting, the amount of voltage reaching the load may be adjusted. The output voltage is proportional to the input signal. At 4 mA input, no voltage will be applied to the load; at 20 mA input, the output voltage will almost equal the line voltage.4.3 Voltage Limit Option (Phase-Angle Fired Units Only)The output voltage of the controller can be limited by adjusting the trimmer on the printed circuit board. Turning the adjustment clockwise will increase the out put voltage limit. This control will operate over a range of about 20% to full output. Ordinarily, this adjustment is used to protect heaters that cannot operate on full line voltage, or to limit the maximum heating of a process.4.4 Soft Start Option (Phase-Angle Fired Units Only)The soft start circuitry is used to slowly turn on the voltage from the controller to the load. It is used to protect the controller when it is operating into loads having high-current, turn-on characteristics, e.g., quartz or tungsten heaters. The output voltage will rise from zero to full output over various times, depending on the time option selected.The soft start circuit presents an initial high impedance which is inserted between the signal source and the controller. This impedance decreases in value with time. Soft start action can be seen as the input signal slowly changes from 4-20 mA when full output is required.4.8 TroubleshootingIf the power controller is not functioning properly, refer to these troubleshooting procedures.Symptom:No heat or reduced heat output.Possible Cause(s)Action1. Loss of line voltage.Check powersupply.2. Line fuse or controller fuse blown.Check heater forshort circuit andcorrect problem.3. No input signal.Check signalconditioner.4. Malfunction on trigger board.Consult factory.5. Open SCR Consult factory.Troubleshooting Flowchart Symptom: Heaters will not turn off.Section 6.

美国Omega校准入门手册

美国Omega校准入门手册

什么是校准?简言之,校准是对设备进行调整以使其达到厂商规格的过程。

校准有时候也可以定义为发布数据。

这些数据包括报告或校准证书,它们向最终用户保证产品符合规格并且还可能符合外部标准,例如国际标准化组织的标准。

例如,该组织的ISO 9001标准为行业设定了全球性规格。

公司遵守这些标准,以确保其产品和服务为供应商和客户所接受。

校准的第二个定义称为认证更恰当。

有设备需要校准的公司可能把该设备送到计量/校准实验室,在那里,技术娴熟的技师使用自身必须达到严格校准要求的测量/测试仪器,将设备调整到符合规格或者确认设备已经符合规格。

在工业过程中使用的全部或者一部分组件都可以校准。

例如,温度校准可能包括仅校准探头、仅校准仪器或者校准与仪器连接的探头(系统校准)。

一般而言,校准设备或校准器的精度至少要比被校准设备高四倍。

通常,设备有一个校准范围,技师在此范围内的不同数据点检查规格。

正如Mike Cable 在《校准:技师指南》中解释的那样,“校准范围定义为‘限值之间测量、接收或传送数量的区域,该区域通过声明范围下限值和上限值表示。

’ 限值由零位值和范围值确定。

零位值该范围的下限。

范围定义为范围上限值与范围下限值之间的代数差。

”在校准过程中进行的调整必须要在某些公差范围内。

这类公差表示相对设备规定精度的极小的、容许偏差。

以在企业内部进行、由第三方实验室进行或者由厂商进行。

再校准频率因设备类型而异。

例如,决定何时再校准一个流量计主要取决引言如果不校准,最先进的工业设备也不会有太大作用。

通过校准,对一台设备进行的调整可以确保它按预期工作,可以确保我们可以依靠该设备提供可预见的、达到质量标准的精确结果。

本白皮书由Omega Engineering 提供,它解释了什么是校准,为什么校准很重要,以及校准如何起作用。

其中对NIST可溯源性进行了定义和讨论,并且包括对基本校准的分步说明。

本文还讨论了企业内部校准与实验室校准,并介绍了主要校准设备类型。
