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。
氧化锆说明书1
其中E是氧电势, R是气体常数,T是绝对温度值, PO2 INSIDE是氧在氧化锆管里部的气压值
,PO2 OUTSIDE是氧在氧化锆管外部的气压值.根据公式当氧化锆管里部和外部的氧浓度不同时,就会产生相应的氧电势.
从计算公式可知道当氧化锆管里部和外部的氧浓度相同时,氧电势应该是0毫伏.
220V的灯泡来替代加热器进行测试,当加热电压输出时(发光二极管闪亮时,电灯泡也应该同时闪亮.当一切测试正常后再把加热器接入.这样测试比较保险,不易损坏加热器

.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。

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。

In the most cases, however, the sensor must be dismounted for a calibration in air.When dealing with biotechnological processes which require sterile conditions, the sensor cannot be removed for calibration. Here, calibration must be performed with aeration directly in the process medium (e.g. after sterilization).The calibration procedures for these two common applications are described on the following pages. Of course, other combina-tions of process variable and calibration mode are possible.Note:When a 2-point calibration is required, the zero point calibration should be performed prior to saturation or concentration cali-bration, resp.All calibration procedures must be performed by trainedpersonnel.Zero point calibrationNote:In Hold mode the controller output acts as configured (Y = const. or Y = 0).50 %X w10 / (1.00)20 / (2.00)30 / (3.00)40 / (4.00)50 / (5.00) ControlleroutputYProportional action (Gradient K C[%])Neutral zone (Y=0)Tolerated deviation from setpoint.The setting “010%”, for example, permits a deviation of ±5 % from the desired value without activating the controller.Pulse length / pulse frequency controllerPulse length controller (PLC)The pulse length controller is used to operate a valve as an actuator. It switches the contact on for a time that depends on the controller output. The period is constant. A minimum ON time of 0.5 sec is maintained even if the controller output takes corresponding values.Pulse frequency controller (PFC)The pulse frequency controller is used to operate a frequency-controlled actuator. It varies the frequency with which the contacts are switched on. The maximum pulse frequency [pulses/min] can be defined. It depends on the actuator.The Contact ON time is constant. It is automatically calculated from the user-defined maximum pulse frequency:Output signal (switching contact) of pulse frequency controllerOutput signal (switching contact) of pulse length controllerOperation with automatic cleaning system“EasyClean” is a separate automatic cleaning system. The cleaning cycle is activated according to the cleaning interval defined during configuration (Pg 55).Calibration error messagesNoteThe worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator (Smiley becomes “sad”).

7.安装与调试7.1安装位置要求控制用氧传感器（前氧传感器）安装布置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。
图4前氧传感器安装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。
图5后氧传感器安装位置图7氧传感器安装凸台7.2 安装方向要求氧传感器的装配位置选择应注意避免路面砂石直接冲击或飞溅到氧传感器的外壳及传 感器的线束上。
氧传感器安装方向应尽可能减少冷凝水在氧传感器头部附近聚积，避免排气中冷凝水损 坏锆元件。
氧传感器头部应朝下装配，且其装配孔轴心线与水平面夹角不小于10度。
图6 氧传感器安装角度7.3 安装凸台要求：装配凸台材料：不锈钢凸台最小外直径：不小于26毫米 凸台推荐最大厚度：不大于13毫米 （9～13毫米之间为佳） 螺纹孔尺寸：M18×螺纹质量：表面应无行刺，砂眼，或 其他任何可能影响安装和拆卸的缺陷安装表面平面度为，表面粗糙度为，表而对安装孔心和垂直度为。
