PE氧探头说明书
PE CS/CCS系列氧探头使用说明书使用前务必仔细越多！1．准备：1.1 要确保氧探头顶部锆头部分运输安全，因此有一个塑胶部件用来代替原有的锆件，通过旋开外管，可以拿下塑料元件已安装原来的锆件。
锆件将放入一个小的塑料容器内运输，他将被装进测量单元的终端连接盒。
如果氧探头交付，准备安装，你会发现一个随附的包装，即以上说明的这一点。
注意：陶瓷外管和锆件上的安装孔是不对称的，可以通过轻微的旋转调整，使它们安装到一起。
在除去塑胶部分安装好锆件后，外管必须逆着弹簧压力旋回。
注意：1.1是探头出口包装的首选的方法。
CCS 2000型准备交货安装时锆件已不能移动。
1.2 氧探头使用必须提供参比气，氧探头有连接参比气的接口。
参比气可以从ESS-ELECTRONIC单元提供，但事先要用硅胶管将其与接氧探头连接起来。
我们建议硅胶管型4 × 1,5或3 × 1,5 。
如果需要烧炭功能（几乎所有渗碳气氛都是必要的），供气单元可以提供一定量的必要的烧炭气体。
更多信息查询5.22，5.23。
2. 氧探头的插入和安装氧探头可以直接插入热炉内，需要的步骤描述在（1）内一定要小心太热和易燃的炉内气氛外泄。
这些气体有毒或具有潜在的危险。
2.1使用软管连接参比气到氧探头，通过调节参比气流量，使参比气值流量大约为5－10l/h。
2.2连接控制器的两个插头（圆柱形，银色的接头，一个热电偶，一个为测量电压）。
一般配置如下：探头电压：2极插头，1为正，2为负；温度：4极插头，4为正，3为负；电机：5极插头，1，2和PE。
2.3连接运行电压适用于机械装置旋转，使用红色直角连接器（电机缓慢旋转—每小时2圈－几乎看不到）。
2.4从控制器的显示中观察升温及电压上升。
2.5当炉温达到要求，氧探头准备工作，有可能测量电压读数显示值过低或者过高。
这是一些残留污物蒸发的结果（油污等），正常情况通常在2－3小时后停止。
2.6必须控制正确的参比气流量。

.氧传感器(四线芯片型)说明手册1。
概述氧传感器是现代发动机管理系统中必不可少的重要部件。
它用于检测汽车发动机排气管内燃烧废气中的氧含量，从而确定发动机的实时空燃比状态。
根据不同的氧浓度，传感器会向发动机电子控制模块输出不同的电压信号，作为系统闭环燃油修正补偿控制的重要依据。
由于氧传感器的应用，发动机在大多数工况下都能工作在理想的空燃比状态，从而获得良好的排放特性和燃油经济性。
该公司的加热型氧传感器体积小、起燃快，使发动机管理系统能够尽早实现系统的闭环燃料管理控制。
图1氧传感器2的外观。
工作原理氧传感器采用扁平结构的多层氧化锆陶瓷作为核心元件。
氧化锆元素的工作原理相当于一个简单的固体原电池。
根据电化学原理，由于氧离子浓度的不同，两侧电极之间会存在电位差。
由于外电极暴露于废气，氧离子浓度将根据实际工作条件而变化，而内电极是参考空气，并且氧离子浓度是恒定的。
当发动机的空燃比稀时，排气中的氧离子浓度相对较高，并且内电极和外电极之间的氧离子浓度差小，即电势差小，并且氧传感器的输出电压信号接近0V。
相反，当空燃比浓时，排气中的氧离子浓度相对较低，并且内电极和外电极之间的氧离子浓度差大，即电势差大，并且传感器的输出电压接近1V。
氧气传感器的典型响应曲线如下图所示。

Operating ManualGWO 5610Dissolved Oxygen Sensors for GMH 5630, GMH 5650Specification:Measuring range:Oxygen partial pressure: 0 ... 1200 hPa O2Temperature:-5,0 ... 50,0 °CElectrodes:Active membrane type platinum/lead, integrated-NTC-ResistorResponse time:90% in 10 sec., temperature dependingLife time: 3 years or more, depending on application and maintenanceOperating pressure:max. 3 barShaft diameter:Ø 12,0 ±0,2 mmLength over all:approx. 170 mm incl. cable glandIntegration length:approx. 100 mmWeight:approx. 120 gConnection:approx. 2 m cable, 7-pole bayonet plug.(optional longer cables possible)Working temperature:0 ... +40°CStorage temperature: 0 ... +60°CStandards and directives:The sensors comply with the following Council Directives on the approx-imation of the laws of the Member States:2011/65/EU RoHSApplied harmonised standards:EN IEC 63000 : 2018Note: The sensors contain lead, but according to Annex IV [1b] / forsensors with "lead anodes in electrochemical oxygen sensors"this is exempted from the restriction.Scope of supply:∙Sensor body∙ 2 Membrane heads∙Electrolyte∙Filling pipette∙ 2 polishing foils (plastic, pink)GHM GROUP - GreisingerGHM Messtechnik GmbH | Hans-Sachs-Str. 26 | 93128 Regenstauf | GERMANYTel.: +49 9402 9383-0 | | www.greisinger.deDesign of Sensor GWO 5610Lifetime:At the end of the Lifetime, the signal of the sensor is dropping rapidly. The sensor evaluation in % therefore e can only be taken as a relative measure. An evaluation of 70% does not mean that 70% of lifetime is left, but that the electrode signal has 70% of a good state reference.Note: The sensor state evaluation will be stored after a successful calibration of the oxygen sensorThe nominal lifetime may be reduced due to the application. Negative effecting are:- Extreme storage and operation temperature- D irty water during measuring- Mechanical stress to sensor membrane- Dry storage of filled sensor- Permanent use at higher CO 2-concentrationsMounting/Operation Position:The optimum position is with sensor membrane pointing downwards.Measuring Precision: The precision can be influenced due to:- To less flow- Water and sensor temperature have to be the same, most exact measuring is done, when calibrated at measuring temperature.Generalfilling hole shaft membrane head platinum elec-trode protective flask The oxygen sensor is an active sensor. It consists of a platinum cathode, a lead an-ode and potassium hydroxide (KOH) as an electrolyte. If oxygen is present, it is re-duced on the platinum cathode and the sensor delivers a signal. If no oxygen is pre-sent, no signal is delivered. The anode is consumed by the oxygen measurement.The sensor ages. Furthermore, the sensor loses liquid through the permeable mem-brane, in particular, when it is stored in dry air. Therefore, it should be checked andmaintained regularly and replaced as necessary. (p.r.t. sensor maintenance)Make it a rule to always store the electrode in a humid environment- in the storage flask filled with water or- in another container filled with waterIf electrode has not been used for some time, clean membrane with softcloth and remove deposits, if any (algae, bacteria etc.).Attention: The membrane is delicate – if damaged, caustic electrolytegets lost and the sensor shows wrong signal. DesignThe electrode housing is made of ABS. With the exception of the electrode shaft all parts need to be maintained regularly and be replaced if necessary. o Protective flask : The protective flask is used to moisten the membrane. This prolongs service life of the electrode. The protective flask contains water. Attention ! Use water only; never use potassium chloride (KCI); this is only re-quired for storage of pH-electrode.o Membrane head : the membrane head is covered with a Teflon membrane. It will be filled with KOH electrolyte and screwed onto the electrode shaft (no airbubbles). Damages in the membrane, large air bubbles or air bubble rings in the membrane head will result in erroneous measurements. This may also be the rea-son for errors in the calibration.The membrane head (GWOK 02) is a spare part and can be ordered individually. o Filling hole : If the electrode is used at high temperatures or if it has been stored without its protective flask for a longer period of time, some electrolyte will be lostdue to evaporation. Please refer to Refilling description below.DANGER Attention when working with electrolyte: The electrolyte is caustic! (strong base, KOH) Avoid contact to skin, protect Your eyes !Visible Residues in the Inner of Membrane Head:As a reaction product in operation, there will be lead oxide (red and brown – from the reaction with oxygen) and lead carbonate (white – from the reaction of carbon dioxide) in the inner of the sensor.These substances may accumulate visibly at the membrane, but usually have now negative effect on the operability. Within a maintenance cycle the residues can be washed off the membrane nearly completely.Significant deposits on the membrane and matt platinum electrode.Deposits already have an effect on the measurement.=> Carry out maintenance to remove these.Slight deposits on the edge of the electrode, predominantly blank platinum elec-trode.No significant influences on the measurement to be expected.=> Maintenance not absolutely necessary.Deposits on the membrane, bare platinum electrode.=> no maintenance required.Polished platinum electrode during maintenance.Before screwing the membrane head on sensor body again they should be washed off, to avoid them getting in be-tween platinum cathode and membrane.A fast occurrence shortly after first filling or an unusual high amount of them (e.g. within some days) may be a sign of air in the sensor – either because of incorrect filling (bubbles), not sufficiently closing membrane head or filling screw or a leaking membrane.First start of operation of dry sensor GWO 5610 / Refilling of GWO 5610The GWO 5610 can be delivered dry as an option. Therefore the sensor is easily storable over a long time.The sensor has to be filled timely towards the measuring. After filling a time of ~ 2 hours has to be considered, until the sensor has stabilized.Wear suitable gloves*) and protect your eyes with safety goggles when filling the electrolyte!Do not touch the electrolyte with bare skin, if there was contact rinse sufficiently with water.Material:∙Sensor GWO 5610 with membrane head∙Filling-pipette∙Electrolyte KOH∙Flat blade screw driver∙Paper towel∙Suitable gloves *), safety goggles∙Wash basinFirst Filling:∙Check membrane head GWOK 02: is it in good state? Is Mem-brane undamaged?∙Open filling screw∙Fill pipette with KOH∙First fill the membrane head up to ¾ of its height, screw onmembrane head tightly, rinse excess KOH with water.∙Then carefully fill the sensor, try to flick at the shaft from time totime, helping air bubbles coming out. In sum the sensor fillingtakes around 5 ml.∙If there are no more air bubbles and the filling hole is full, closewith filling screw.∙Rinse excess KOH with waterFigure: Filling with pipette ∙Turn sensor upwards: Are air bubbles visible below the mem-brane? If so: Refill once again.∙Wait approximately 2 hours for the sensor to stabilize, afterwards calibrate the sensor – the electrode state evaluation should deliver 100%.*) suitable gloves: Acc. to DIN EN 420, e.g. natural latex, natural rubber, butyl rubber, nitrile rubber,polychloroprene, fluorinated rubber.Sensor Maintenance of GWO 5610If the sensor can no more be calibrated or only unstable values are displayed, it has to be maintained or even or the membrane head has to be exchanged.Wear suitable gloves*) when filling the electrolyte! Do not touch the electrolyte with bare skin. If there was contact rinse sufficiently with water.Material:∙Sensor GWO 5610, eventually spare membrane head GWOK 02∙Filling pipette∙Electrolyte KOH∙Flat blade screw driver∙Paper towel∙Polishing foil (pink)∙Suitable gloves *), Safety goggles∙Wash basinMaintenance is basically the same as the first filling, but first the membrane head is unscrewed and the old electro-lyte is removed.Unscrew the membrane head and the refill opening - Attention! Old electrolyte will now leak out!If the membrane is undamaged and free of deposits, the membrane head can be used again.The platinum electrode must be bright and free of deposits!Wipe off existing deposits from the platinum electrode with a cloth, if necessary polish the electrode using the pink polishing foil.The filling of the sensor is like described bevor.Hints for Operation:a.) Treat device and sensor carefully. Use only in accordance with above specification. (do not throw, hit againstetc.). Protect plug and socket from soiling.b.) The electrode are only suitable for the devices GMH5630, 5650. Unsuitable devices may lead to the destructionof the measuring device and the oxygen sensor.c.) A protective cap, such as GSKA 3600 in plastic or GSKA 3610 in red bronze is recommended for protection ofthe membrane, e.g. for use in bodies of water.Safety guidelines:This device has been designed and tested in accordance with the safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advises given in this manual will be adhered to when using the device.1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to anyother climatic conditions than those stated under "Specification".2. Do not use these products as safety or emergency stop devices or in any other application wherefailure of the product could result in personal injury or material damage.Failure to comply with these instructions could result in death or serious injury and material dam-age.3.

氧传感器技术手册
氧传感器使用说明书 （第一版）适用零件号：25327985 253599081.概述氧传感器是现代发动机管理系统中必不可少的重要零部件。
它是一种利用电化学工作原理发展出来的电器元件。
氧传感器在现代发动机管理系统的配置机构中被用于探测汽车发动机所排出的燃烧废气中氧的含量，借以判定发动机实时燃油供给空气燃料混合比的实际状态，并通过自身产生的电器反应信号反馈给发动机电子控制模块（ECM），以作为系统燃油管理系统的闭环燃油修正补偿控制的重要依据，使燃油管理子系统能够更加精确地控制调整发动机各种工作状态下的空气燃料混合比；并在绝大多数工况下使系统保持在理想空燃比工作状态，以便获得更加优良的汽车排放控制特性和燃油经济性。
氧传感器的输出信号为0 ~ 1V的交变电压信号。
传感器可根据发动机所排燃烧气中氧的含量高低自动感应和探测并向发动机电子控制模块输出这一高低变化的电压信号。
现代发动机管理系统采用的氧传感器有两种主要类型：非加热型氧传感器和加热型氧传感器。
装配在发动机排气歧管上的氧传感器，由于可以利用发动机所排出燃烧废气的余热进行快速加热，故可使用价格低廉的非加热型氧传感器；当氧传感器的安装位置受到整车布置限制，氧传感器距离发动机排气歧管出口较远时，由于不能利用发动机燃烧废气对于传感器迅速加热，此时必然需要采用加热式氧传感器。
加热式氧传感器的内部设计有热敏电加热元件，可利用系统供电电压强制使氧传感器加速预热，促使其快速起燃，及早实现系统的闭环燃油管理控制。
2. 工作原理德尔福公司生产的氧传感器是采用氧化锆元件作为传感器的基础元件。
氧化锆元件是一种通体充满无数微孔的陶瓷基础元件外面镀有氧化锆涂层，该涂层外测暴露于发动机燃烧废气之中；涂层的内侧透过含微孔的陶瓷元件与大气相通。
集中在氧化锆内外两侧电极之间氧含量的差别形成的微分电压信号。
当氧化锆元件被电流加热或被流经传感器的发动机燃烧废气加热所激活，空气经过通体充满无数微孔的陶瓷基础元件进入氧化锆元件的内电极，而燃烧废气流经氧化锆的外电极。

Otherwise, the assembly may not be insert into the process.4.2PolarizationThe sensor was tested in the factory for perfect functionality and is supplied ready for operation.To prepare for calibration, proceed as follows:1.Remove the sensor protective cap.2.Place the externally dry sensor in atmospheric air. The air should be saturated with watervapour. Therefore, install the sensor as close to the water surface as possible. Whencalibrating the sensor membrane, make sure the membrane remains dry. Therefore, avoidany direct contact with the water surface.3.Connect the sensor to the transmitter and switch on the transmitter.4.Switch-on the transmitter.If you connect the sensor to the transmitter Liquisys M COM223/253, polarisation isautomatically performed after switching on the transmitter.5.The polarisation time takes about 1 hour.!Note! Polarisation starts high, then drops gradually. You will recognise the end of polarisation when the display stabilises and remains practically constant."Caution!•When you remove the sensor from the medium, protect the sensor from strong sunlight.•Make sure you comply with the instructions for commissioning and calibration in theOperating Instructions of the transmitter.4.3CalibrationCalibrate the sensor (calibration type "Air") immediately after it’s polarization.1.Remove the sensor from the medium.2.Clean the outside of the sensor with a damp cloth. Then dry the sensor membrane e.g.by using a tissue.3.If the sensor is removed from a closed pressure system with a process pressure greaterthan atmospheric pressure:–Open the membrane cap to equilibrate the pressure and clean the cap if necessary.–Replace the electrolyte filling and close the membrane cap again.–Wait for the polarisation time to end.4.Then wait while the sensor adjusts to the temperature of the ambient air. This takesabout 20 minutes. Check that the sensor is not in direct sunlight during this time.5.If the measured value display on the transmitter is stable, carry out the calibration inaccordance with the Operating Instructions of the transmitter.6.Place the sensor in the medium again.!Note!Make sure you comply with the instructions for calibration in the Operating Instructions of the transmitter./worldwideKA284C/07/en/06.05Printed in Germany / FM+SGML 6.0 /DT71002048。

O2 传感器说明书
To ensure that the new O2sensors work smoothly under process conditions of diverse or even extreme nature, only the highest quality materials have been used to manufacture the sensors.The sensors are equipped with the in-dustrially-proven VarioPin (VP) connector and are ideally suited for use in moist or even wet environments. This connector is absolutely watertight (IP 68), extremely robust, and fully sterilizable. In a test pro-cedure, the VP connector was immersed for 1000 hours in water at 1 bar (14.5 psi) ex-cess pressure (corresponding to a depth of 10 meters). Result: The VarioPin connector remained absolutely impervious.This new range of DO sensors offers a substantially improved set of features. Apart from the above mentioned cableconnection, the differences are primarily to be found in the design of the sensor inner bodies. The special low-ppb version (InPro 6900) has a detection limit of 1 ppb at en-hanced signal stability. This has been made possible by a newly developed annu-lar cathode with protection ring. The basic InPro 6800 can be easily converted/ upgraded to an InPro 6900 version at any time. The inner body of the low-ppb InPro 6900 enables:– lower DO detection limit of 1 ppb accuracy– faultless measurement values evenat fluctuation of flowThe new InPro series of dissolved oxygen (DO) sensors has been specially developed to provide dependable inline measurementsin processes operating under sterile and hygienic conditions.Apart from the basic InPro®6800, an enhanced version is also available to meet higher requirements- the InPro®6900. In both cas-es, durable material and robust construction guarantee high process reliability.A new family of O2 sensorsContents Brewery News 1A new family of O 2sensorsOxygen measurement made easy Sensors for CIP/SIP proceduresMeasurement of oxygenduring CO 2recovery Oxygen and pH measure-ment in wortRepair or replacement?pH measurement in beerMettler-Toledo GmbH Process Analytics Im Hackacker 15CH-8902 Urdorf Switzerland MarComCH-8902 Urdorf, Switzerland Mettler-Toledo GmbH ProzessanalytikD-35396 Giessen, Germany Archive MarComCH-8902 Urdorf, Switzerland andD-35396 Giessen, GermanySubject to technical changes. © Mettler-Toledo GmbH 01/03Printed in Switzerland.IP 68: In an endurance test, the VarioPin connector was immersed in water at 1 bar (14.5 psi) excess pressure (equivalent to a depth of 10 meters).

These METTLER TOLEDO DO sensors are the first (and so far only sensors worldwide) with EHEDG and 3-A hygiene certification. Construction and manufacture are both carried out in ac-cordance with the most exacting standards for surface finishing. This ensures com-plete fulfillment of the EHEDG and FDA guidelines relating to smooth surfaces for particularly high standards of hygiene.Validation included:complete traceability of source of steelTogether with every D sensor, METTLER TO LEDO also supplies a 3.1B certificate, standard and free-of-charge.The 3.1B certificate provides evidence of the steel's quality so that those steel parts which come into contact with media can be traced back even as far as the steel produc-er, if need be.Intelligent accessoriesThe O 2Sensor-Master enables fast and simple testing of a sensor prior to its use,and the O 2Sensor-Simulator is specially designed for checking the transmitter andthe cable. For maintenance professionals,these are important aids which make reliable functional tests fast and uncom-plicated.InTap 4000/4004 a fully waterproof portableoxygen analyzer.With the InTap 4000/4004 series, METTLER TOLEDO brings to the market a portable oxygen analyzer ideally suited for use in the beverage industry. Three main features characterize this practical “light-weight” unit - rugged construction, precise measurement and ease of operation. Even under the harshest operating conditions,this fully waterproof instrument consis-tently provides reliable measurement data due to the perfect functional compatibility of the optimized measuring chamber and robust sensor. Neither a fluctuation in flow rate, nor extremely low dissolved oxygen concentrations have any influence on the stability of the measurement results. The North American version of the InTap 4000(InTap 4004) is specially designed with an incorporated quick-connect Zwickel ad-apter, which is a standard connection for North American breweries.The integrated software offers a variety of different functions. Not only is it possi-ble to store the measurement data, but al-so, by using the accompanying “Paraly”software, the data generated are easily transferred to a computer for subsequent processing and evaluation. The data can then be processed either with “Excel” or any other preferred spreadsheet program. A high degree of user ergonomics is built in, such as a menu-driven, step-by-step maintenance routine and many other sim-ilar productivity-enhancing operational features.Due to the modular concept of our oxygen sensors, membranes can be ex-changed in a matter of a couple of min-utes, with little effort. On a practical basis this means that the spare parts for the sensor employed in conjunction with the InTap unit are exactly the same as those used worldwide for the other proven (in-line) oxygen sensors from METTLER TOLEDO. Users are alerted by the Senso-Check function if the sensor needs service attention or the instrument requires (re-)calibration.The oxygen analyzer InTap 4000/4004in its protective housing made of high-impact PU is delivered ready for use, com-plete with a cleaning and conditioning set,all other necessary accessories, and is con-veniently packed in a practical, trans-portable case.Intelligent, mobile oxygen measurement using the InTap 4000.Brewery News 1METTLER TOLEDOPrecise, rugged, simple to useOxygen measurement made easy3Typical measuring solution with retractable housing InTrac 776/777 and Inline O 2 sensors InPro 6800/6900.environment. Over and above this, the sen-sor must be made of FDA-listed materials and be able to withstand scouring in or-der to qualify for unrestricted in the industrial ne sensor that meets these requirements is the new METTLER TO 4-electrode sensor. In addition to perform-ing in such harsh con-ditions, the InPro 7108In numerous beverages such as beer,mineral water or sparkling wine, dissolved CO 2is present in large concentrations. This carbon dioxide content acts as a stimulant as well as having an aseptic effect. The de-gree of purity of the CO 2used has to be checked, since the presence of impurities such as oxygen can have a negative influ-ence on both flavor and shelf life of the product. If the CO 2comes from an outside source, the supplier assumes responsibility for the quality of the gas. In breweries and also in champagne production, the natural CO 2emitted during the in-house fermen-tation process is utilized. The purity of the gas is then a matter for the producer.Measurement of oxygen during CO 2 recoveryMETTLER TOLEDOContamination from oxygen can be extremely well detected by using the proven inline oxygen sensors of the InPro 6800/6900 series from METTLER e of these sensor is not limited to the liq-uid phase alone- reproducible and precise measurement is also possible in the gas phase. This multipurpose functionality makes these sensors an ideal solution for CO 2recovery plants. Uniform design of the equipment and spare parts, such as mem-branes and cables, reduces the learning curve for individuals responsible for oper-ation and maintenance procedures.During preparation of the wort, careful supervision of pH values and dissolved oxy-gen content is an essential factor in con-trolling the flavor of the final product in beer production. In breweries these param-eters are best measured using online sys-tems, whereby the values can be docu-mented and evaluated. When selecting in-line sensors for wort production, it is critical to select systems that function per-fectly at elevated temperatures and in the presence of high solids content. For cost-efficiency, the sensors should also be able to withstand repeated cleaning cycles with hot caustic solutions.Online measurement systems certain-ly pay off, by avoiding the additional labor and time of grab samples followed by lab-oratory analysis. Even more important, often by the time a sample is analyzed in the laboratory the pH or dissolved oxygen content may have deviated from the condi-tions in the controlled process environ-ment. Online measurement ensures per-fect, continuous process documentation. Only in this way is it possible to maintain a consistent and reproducible, high-quality product.The highly valued online sensors of the InPro 6800/6900 series, widely em-ployed for checking the (very low) rest oxy-gen concentration in the final beer, are also extremely well suited for determining the (high) oxygen values in wort. The ro-bust, pressurized InPro 2000 pH electrodes have also proved extremely suitable for measuring pH values in wort.For maximum return on investment and highest operational efficiency, these sensors can be mounted to the process us-ing manual or automated retractableComplete documentation of the pH value and oxygen concentration during wort preparation.housings, which allow withdrawal of asensor from an ongoing process for inspec-tion and calibration. The stringently test-ed, sterilizable double lock system of thehousing allows subsequent reinsertion ofthe sensors under fully aseptic conditions.Oxygen and pH measurement in wortBrewery News1METTLER TOLEDO5Repair or replacement?Fouling of the glass membrane or di-aphragm(s) of a pH electrode has negative effects on the performance of the electrode generally. However, fouling does not always lead to an irreparable defect.Through special cleaning procedures,many electrodes can be restored to a satis-factory operating condition.O xygen sensors too, are subject to a natural aging process and are then no longer able to fulfill the specifications guaranteed at the time of delivery. This is particularly true in respect of the insula-tion resistance of the inner body, which de-teriorates over time due to mechanical andBrewery News 1METTLER TOLEDOthermal stress. One result of a deteriorated inner body is over-range transmitter read-ings. By replacing the inner body, thesensor can be returned to original specifi-cations.Service technicians from METTLER TOLEDO are equipped with sophisticated diagnostic equipment to verify defective sensors and to issue a written report onthe findings. Please contact your local Mettler-Toledo Service office or your local authorized METTLER TO LEDO agent for more information.Our service technicians will be pleased to advise you about suitable O-ring material.Sensors directly in contact with the sample medium are subject to con-tinuous wear and tear, which at some point reaches such an advanced stage that the sensors must be repaired or replaced.6METTLER TOLEDOlaboratory electrode in use.7pH measurement in beerThe pH value of beer is an important quality criterion that has a lasting affect on the taste. As an alternative to mobile sample measurement or test measurements analyzed in the laboratory, continuous measurement directly in the beer processing equipment offers many advantages.Permanent monitoring of the pH value allows continuous product control.The results of in-line measurement are not altered due to sampling errors or through other influences on the sample to be measured.Automatic intervention in the process is possible via the pH transmitter's control functions. Alarm limits can be programmed to prevent filling when the product is outside of a user-defined tolerance range.The use of a pH electrode with integrated temperature sensor allows simultaneous temperature monitoring, and results in correct measurement values through automatic temperature compensation .The appropriate sensorMost successful of all has been a pH electrode with FRISCOLYT ®, a liquid elec-trolyte that is well tolerated with foodstuffs and drinks. Its special composition pre-vents contamination of the electrode,which is a basic prerequisite for correct measurement results. The pH electrode InPro ®2000 is additionally equipped with a Pt100 or Pt1000 temperature probe.Correct installationIn addition to multiple other locations in the process, a final pH check is usually performed just prior to the filling process.Since considerable fluctuations in pressure can occur at this point in the beer line, the pH electrode has to be installed on the in-let side of the pump. The InFit 764-50 CIP housing accepts the pH sensor and allows pressurization up to 6 bar (187 psi). It canbe fitted directly into the beer line via a flange or the INGOLD DN25 weld-in sock-et. Alternatively, there is also a retractablehousing InTrac 776 available, which allows cleaning, maintenance and calibration of the sensor even when the beer feed line is in production. The appropriate measuring device The pH 2100 e transmitter offers a highdegree of performance with very simple op-eration. Calibration, programming and configuration are carried out under menu control in plain language. Four different user levels allow access to only those au-thorized via password number. The backlit display is always easy to read even in poor light conditions. The device corresponds in design, construction and layout to the familiar O 24500 oxygen transmitter that is commonplace in many breweries, i.e. the same instrument philosophy for differentmeasurement parameters. The InPro 2000 pH electrode with liquid electrolyte and integrated temperature sensor guarantees reli-able measurement results.The InFit ®764-50 CIP housing is installed directlyinto the beer line.What are the essential points?Brewery News 1METTLER TOLEDOThe pH transmitterpH 2100 e combines a high degree of performance with ease of operation.Oxygen , conductivity and pH transmitters with PROFIBUS PA interfaceCommunication systems in the field of (process) analytical measurement are moving more and more towards the use of digital technology. The advantages over conventional analog data transfer via 0/4...20 mA lie mainly in the ability, along with the actual measurement signal itself, to exchange additional information between the process control system (PCS)and the analytical measurement device on a two-way communication basis.For some years, METTLER TOLEDO has b een offering transmitters with HART ®Communication which superim-poses a digital signal on the customary 4 -20 mA DC analog signal. This enables the transfer of additional information than just a measurement signal.From now on, transmitter units are al-so available which incorporate a fully dig-ital PROFIBUS PA interface according to the “Profile for Analytical Devices, Version 3”, suitable for measurement of dissolved oxygen, electrolytic conductivity (conduc-tive and inductive) and pH value.Simple connection to the PCS through Plug & Play.Connection to the PROFIBUS DP level is possible either by direct linkage or through a segment coupler. The maximum bit rate of 12 Mbits/s on the DP lane is thereby preserved.The instrument interface employs the FISCO model to ensure in-trinsically safe networks. The ex-isting well-proven functions such as automatic calib ration (Calimatic ®), sensor diagnos-tics (SensoCheck ®) and para-meterization can be accessed via the PCS just as easily and comfortably as before.INGOLDLeading Process AnalyticsMettler-Toledo GmbH Process Analytics Im Hackacker 15CH-8902 Urdorf Switzerland。

Underconstant conditions, this flow is proportional to the oxygen content of the medium.This current is converted in the transmitter and indicated on the display as an oxygen concentration in mg/l,as a saturation index in % SAT or as an oxygen partial pressure in hPa.Memosens technology Maximum process safetyThe inductive and non-contacting measured value transmission of Memosens guarantees maximum processsafety and offers the following benefits:•All problems caused by moisture are eliminated.–The plug-in connection is free from corrosion.–Measured value distortion from moisture is not possible.–The plug-in system can even be connected under water.•The transmitter is galvanically decoupled from the medium. The result: No more need to ask about"symmetrically high-impedance" or "unsymmetrical" (for pH/ORP measurement) or an impedanceconverter.•EMC safety is guaranteed by screening measures for the digital measured value transmission.•Application in explosion-hazardous areas is unproblematic; the integrated electronics are intrinsically safe.Data safety through digital data transferThe Memosens technology digitalizes the measured values in the sensor and transfers them to the transmittercontactlessly and free from interference potential. The result:•An automatic error message is generated if the sensor fails or the connection between sensor and transmitteris interrupted.•The availability of the measuring point is dramatically increased by immediate error detection.Easy handlingSensors with Memosens technology have integrated electronics that allow for saving calibration data andfurther information such as total hours of operation and operating hours under extreme measuring conditions.When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used tocalculate the current measured value. Storing the calibration data in the sensor allows for calibration away fromthe measuring point. The result:•Sensors can be calibrated under optimum external conditions in the measuring lab. Wind and weather doneither affect the calibration quality nor the operator.•The measuring point availability is dramatically increased by the quick and easy replacement of precalibratedsensors.•The transmitter does not need to be installed close to the measuring point but can be placed in the controlroom.•Maintenance intervals can be defined based on all stored sensor load and calibration data and predictivemaintenance is possible.•The sensor history can be documented on external data carriers and evaluation programs at any time. Thus,the current application of the sensors can be made to depend on their previous history.2Endress+HauserOxymax COS51DEndress+Hauser 3Measuring systemA complete measuring system comprises:•The digital oxygen sensor Oxymax COS21D •A transmitter, e.g. Liquiline CM42•An appropriate measuring cable, e.g. CYK10•Optional: an assembly, e.g. fixed installation assembly CPA442, flow assembly CPA240 or retractable assembly CPA475InputMeasured variableDissolved oxygen [mg/l, μg/l, ppm, ppb, % SAT or hPa]Temperature [° C, °F)Measuring rangeWiringElectrical connectionThe sensor is electrically connected to the transmitter by means of the special measuring cable CYK10.Example of a measuring system 1Liquiline CM422Measuring cable CYK103Digital oxygen sensor Oxymax COS21D 4Fixed installation assembly CPA442Measuring rangeRecommended operational range COS21D-A0.01 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa 0.01 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa COS21D-B 0.001 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa0.001 to 2 mg/l 0 to 20 %SAT 0 to 40 hPaCOS21D-CSpecial measuring cable CYK10Oxymax COS21D4Endress+HauserPerformance characteristicsResponse timeFrom air to nitrogen at 25 °C (77 °F)•t 90 : < 30 s •t 98 : < 60 s Reference operating conditionsSignal current at air 1)•COS21D-A: 60 nA (40 to 80 nA)•COS21D-B and COS 21D-C: 300 nA (180 to 500 nA)Zero current< 0.1 % of the current in airMeasured value resolution•COS21D-A: 10 μg/l (10 ppb)•COS21D-B and COS21D-C: 1 μg/l (1 ppb)Maximum measured error ±1 % of measured value 2)Repeatability ±1 % of measured value Long-term driftInfluence of medium pressure Pressure compensation not necessary Polarization time•COS21D-A and COS21D-C: < 60 minutes •COS21D-B: < 12 hoursOxygen intrinsic consumption•COS21D-A: Approx. 20 ng/h in air at 25 °C (77 °F)•COS21D-B and COS21D-C: Approx. 100 ng/h in air at 25 °C (77 °F)InstallationAngle of installationReference temperature:25 °C (77 °F)Reference pressure:1013 hPa (15 psi)1) For the reference operating conditions indicated2) In accordance with IEC 60746-1 at nominal operating conditionsZero-point drift:< 0.1 % per week at 30 °C (86 °F)Measuring range drift:< 0.1 % per week at 30 °C (86 °F) 1)1)under constant conditions eachPermitted angle of installationOxymax COS51DEndress+Hauser 5EnvironmentAmbient temperature range –5 to +135 °C (23 to 175 °F)Storage temperature–10 to +60 °C (10 to 140 °F) at 95% relative air humidity, not condensingIngress protectionIP 68 (10 m / 33 ft) water column at 25 °C (77 °F) during 45 days, 1 mol/l KClProcessProcess temperature•COS21D-A and COS21D-C: -5 to 135 °C (23 to 275 °F)•COS21D-B: -5 to 100 °C (23 to 212 °F)Process pressure•COS21D-A: 0 to 4 bar (0 to 58 psi)•COS21D-B and COS21D-C: 0 to 12 bar (0 to 174 psi)Minimum flow rate•COS21D-A: 0.02 m/s (0.07 ft/s)•COS21D-B/C: 0.10 m/s (0.33 ft/s)Mechanical constructionDesign, dimensionsWeight 0.2 kg (0.44 lbs)MaterialCaution!

2.工作原理
氧传感器采用平板结构多层氧化锆陶瓷作为核心元件。
氧化锆元件工作原理相当于一个简单的固体原电池。根据电化学原理，其两侧电极间将由于氧离子浓度的差异而存在电势差。外侧电极由于暴露于废气中，氧离子浓度将根据实际工况的不同而变化，而内侧电极为参考空气,氧离子浓度是不变的.当发动机空燃比为稀时,废气中氧离子浓度相对较高，内外电极间氧离子浓度差就小,亦即电势差就小,氧传感器的输出电压子浓度差就大,亦即电势差就大,传感器的输出电压接近1V。氧传感器典型响应曲线见下图。

使用说明书
1.概述
氧传感器是现代发动机管理系统中必不可少的重要零部件。它用于探测汽车发动机排气管中燃烧废气中氧的含量，借以判定发动机实时空燃比状态。根据氧浓度的不同，传感器将输出高低不同的电压信号给发动机电子控制模块（ECM），作为系统闭环燃油修正补偿控制的重要依据。由于氧传感器的应用，发动机能在绝大多数工况下工作在理想空燃比状态，从而获得良好的排放特性和燃油经济性。
前氧传感器应安装于可以代表所有汽缸排出废气状态的位置附近。此外各个气缸排气气流混合均匀，避免只探测到发动机某单一汽缸的废气氧浓度，从而影响整个系统对发动机实时燃烧状态作出正确判断。为了使系统在冷启动时尽快进入闭环控制，传感器应安装在离发动机排气歧管出口较近、气流温度较高的位置。

三元催化器功能监测用氧传感器（后氧传感器）安装布置：
后氧传感器的理想安装位置推荐在三元催化器下游外壳的延长管上且距催化器载体后端面100～300毫米以内。当催化器与排气消音器之间带有装配法兰时，为了防止因联结法兰漏气造成错误判断，应将传感器布置在三元催化器一侧联结法兰上游。
