英国CITY英国CITY氧气传感器概况所有的氧气传感器都是自身供电,有限扩散,其金属-空气型电池由空气阴极,阳极和电解液组成。
（图一）氧气传感器简单来说是一个密封容器(金属的或塑料的容器),它里面包含有两个电极：阴极是涂有活性催化剂的一片PTFE(聚四氟乙烯),阳极是一个铅块。
这个密封容器只在顶部有一个毛细微孔,允许氧气通过进入工作电极。
两个电极通过集电器被连接到传感器表面突出的两个引脚,而传感器通过这两个触角被连接到所应用的设备上。
传感器内充满电解质溶液,使不同种离子得以在电极之间交换(参见图1)。

It is the clients’ responsibility to carry out the necessary tests to determine the usefulness of the products and to ensure their safety of operation in a particular application.Performance characteristics on this data sheet outline the performance of newly supplied sensors. Output signal can drift below the lower limit over time.Temperature Behaviour1) Gradual changesThe output of a 7OX-V CiTiceL varies slightly with gradual tem-perature changes. The behaviour of a batch of 7OX-V sensors is shown opposite. Output was measured at a range of temperatures and expressed as a percentage of the signal at 20°C. The graph shows the mean signal and three times standard deviation.2) Sharp fluctuationsA transient response will occur with sharp fluctuations in tem-perature. For rapid increases in temperature there is a sharp drop in sensor output, and a sharp increase in output for rapid decreases. These responses are transient and should die awayLinearityThe output signal of an Oxygen CiTiceL follows the relationship:S = K log e 1/(1-C)where:S = Output signal;C = Fractional oxygen concentration;K = a constant for the sensor.For most applications the deviation from a linear response will be insignificant, and no compensation needed. For example, the graph below shows the output of a sensor calibrated in air (20.9% O 2). In this case the maximum error in the 0-25% range is »0.5% at around 10% O 2.SAFETY NOTEThis sensor is designed to be used in safety critical applications. To ensure that the sensor and/or instrument in which it is used, are operating properly, it is a requirement that the function of the device is confirmed by exposure to target gas (bump check) before each use of the sensor and/or instrument. Failure to carry out such tests may jeopardize the safety of people and property.深圳市深国安电子科技有限公司地址：广东省深圳市龙华新区牛栏前大厦Ｃ５０７ 网址：ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ．ｃｎ ｗｗｗ．ｓｈｅｎｇｕｏａｎ．ｃｏｍ蒋小姐：１３４ ２８７６ ２６３１ 电话：８６ ７５５－８５２５８９００。

新型氧气传感器在节能减排领域中的应用
新型氧气传感器在节能减排领域中的应用来源：中电网[导读]为适应中国市场的业务需求和发展趋势，英国城市技术公司于2012年底发布了一款专为烟气分析而设计的长效无铅氧传感器——4OXecoLP。
关键词：4OXecoLP氧气传感器随着全球工业化的发展，化石能源在大量消耗的同时，也给环境带来了不小的影响。
在国务院发布的《节能减排“十二五”规划》中，国家对重点行业、重点领域的节能减排措施和目标进行了细化和量化。
在此前提下，与烟气排放、燃烧效率监控相关的排放监测仪器、仪表市场将迎来爆发式增长。
为适应中国市场的业务需求和发展趋势，英国城市技术公司于2012年底发布了一款专为烟气分析而设计的长效无铅氧传感器——4OXecoLP。
传统含铅氧气传感器传统用于排放气体检测的氧气传感器可认为是二电极的金属-空气型电池，它由空气阴极，铅阳极和碱性电解液组成。
阴极是涂有活性催化剂的一片聚四氟乙烯（PTFE）薄膜，阳极是一个铅块，它们被包裹在一个金属或塑料的密封容器中。
空气通过顶部的毛细管进入传感器，阴阳极通过电流收集导线与传感器的两个引脚相连。
当氧气到达工作电极时，发生还原反应：产生的氢氧根（OH-）通过电解液到达铅电极，铅电极发生氧化反应：通过外接一只已知电阻将电流转换成电压，就可以计算出氧气的浓度。
含铅氧气传感器虽说已经有三十多年的历史，但也存在其局限性：（1）燃烧产物影响使用寿命。
燃烧产物一般都含二氧化碳（CO2）、氮氧化物（NOX）和二氧化硫（SO2）等酸性气体。
而传感器内部为碱液，使用时间长之后，碱液PH值下降，燃料铅也会加速消耗，从而缩短传感器寿命。
（2）不符合无铅要求。
含铅的传感器现在虽有RoHS和WEEE的豁免权，但无铅传感器将逐渐取代含铅的传感器，已经成为不可逆转的环保大趋势。
（3）重量大，体积大。
为延长传感器寿命，需要多增加铅的重量。
长效无铅氧气传感器技术特点针对含铅氧气传感器的缺点，第二代三电极长寿命无铅氧气传感器4OXecoLP应运而生。

Honeywell iSeries 智能气体传感器诊断测试说明书
DIAGNOSTIC TESTS FOR THE INTELLIGENT GAS SENSORS, iSERIESTechnical NoteHoneywell introduces the Next-Generationintelligent (iseries) gas sensors. These sensorshave a digital interface, longer life andnumerous built-in diagnostics features.The iseries’ intelligent diagnostic features help enhance the overall instrumentperformance, making them smarter and safer by indicating faults and monitoringhealth, thereby decreasing downtime and cost of ownership.The purpose of this document is to describe the Predictive Calibration and End-of-lifefunctions, and outline the principles of the diagnostic tests.BACKGROUNDAll gas sensors drift over time and eventually need recalibrating, and the amountof drift is strongly dependent on the environment that the sensor is used in.Traditionally, instrument developers, fleet managers or end users would work out forthemselves by experience how often they need to recalibrate sensors, or would use recommendations from the sensor or instrument manufacturer as it is not knownwhat conditions the sensors are being used in. This often results in unnecessarilyfrequent recalibrations which is costly and time consuming.Intelligent FeaturesThe iseries platform uses internal tests to monitor the condition of the sensorand apply algorithms both to compensate for drift and to predict when the sensoraccuracy exceeds a predefined limit and needs recalibrating.It can also predict when it is wearing out and can give warning in advance that thesensor needs replacing. As both the Predictive Calibration and End-of-life indicationuse predictions based on the environment that the sensor is being used.Definition of Diagnostic TestsPredictive Calibration: The calibration process can be very tedious, costly and a time-consuming process. With this function, sensors can predict in advance whenits accuracy is becoming too poor to give a reliable reading. This function helps to identify exactly when a recalibration is required.The sensor can estimate the time to recalibration up to six months in advance. Recalibration intervals will be typically at least twice as long as for conventional sensors and will adapt depending on the environment – with sensors used in more benign environments needing less frequent calibrations than those in aggressive ones.The user can configure the accuracy limit of the sensor, and this will determine the interval at which the calibration is needed. In other words, the tighter the accuracy value, the more frequent calibration needed.The user can therefore trade off accuracy against recalibration interval. There is also a configurable built in fixed interval recalibration countdown timer for applications where legislation requires calibration at certain intervals.End-of-Life: The lifespan of a sensor depends mostly on the environmental conditions at which the sensor is exposed. With this function, the sensor can predict in advance when its sensitivity is falling too low to give a reliable and accurate reading. When the End-of-life function is triggered, the sensor automatically warns the instrument via a set of fault flags sent together with the gas reading. If the fault is detected the instrument can warn the user to stop using the sensor.How was the design of the sensor optimised?Honeywell engineers performed finite element analysis of the water management and electrolyte distribution within sensors and gained an extensive understandingof the optimum designs for retaining the electrolyte in the right place at the right concentration.Subsequently, safety operating area charts were developed based on a combination of fundamental physical theory, modelling and experimental verification to show how sensors will perform and withstand over the full temperature, humidity and time.To validate that the sensor will last in real-world applications, an environmental database was obtained. The database contains hundreds of locations around the world, with temperature and humidity data for 10 years with two hourly resolution. The knowledge of use cases for sensors was combined, for example time spent indoors and outdoors, charging to provide input data on the actual conditionssensors are exposed to in the real world. This information was fed into the models to predict how long sensors will last and how their performance will change in real world conditions, and to assist us in optimising the sensor design for maximum performance and life.The environmental performance data was generated by storing sensors in a rangeof environmental conditions over a two-year period. There were more than 8000 individual gas responses recorded for each gas typeDuring this period, the sensors were tested to generate different databases corresponding to the performance of the sensor at particular environments.The resulting predictive algorithm keeps track of the electrolyte concentration and environmental conditions over time and extrapolates this data with a linear regression in order to accurately predict when does the sensor need to be calibrated or when does the sensor is about to reach its lifespan.How does the predictive model for EoL and Predictive Calibration works?To estimate the EoL and Predictive Calibration, a 30-day time period is defined. During this period, the sensor will keep track of the environmental changes. The model works under the assumption that the sensor will be exposed to similar conditions.For instance, if the sensor has been in an extremely hot and dry environment, the predicted model will calculate the corresponding water loss as if the conditions remained the same; giving warning to the user in order to prevent further dry out. Figure 1 shows how the electrolyte concentration and predicted electrolyte concentration vary for a sensor in an extreme environment. The environment chosen corresponds to a challenging environment for the sensor to survive: during winter, outdoor temperatures can be -40°C or less, and in a heated unhumidified buildingor car, the relative humidity can be extremely low due to the very low water content of the cold outside air. Therefore, a sensor which spends part of the day indoors and part outdoors (a typical ‘field worker’ use case) not only gets very dry in winter but is also expected to function at very low temperatures.A perfect prediction (theoretical) would follow the dashed black line. In other words, the predicted days to recalibration would be exactly equal to the actual days to recalibration.The solid black line shows the true electrolyte concentration, which gets dry (high concentration) each winter but recovers to some extent each summer. The yellow line shows how the concentration has been predicted. The historical relative humidityis calculated from the average of another 30 days prior to that. As the prediction is made over a longer time, it becomes less accurate, mainly because the historical environmental conditions become less representative of the future conditions. How often does the sensor updates the EoL and Predictive Calibration?The diagnostic test runs automatically every 24 hours. However, the test is only performed when the sensor is in sleep mode, so it is highly recommended to change the sensor to sleep mode whenever it is not in use (otherwise the End of Life and Predictive Calibration estimations will not be updated/recalculated, leading to non-accurate results).The sensor needs to be in sleep mode at least two minutes per day, so it can update the EoL and Predictive Calibration values.What technique is used for the diagnostic tests?For this test, a smart indicative gadget is used as a diagnostic electrode. Thenan electrochemical technique called square wave voltammetry is applied to the electrode.The technique is a linear potential sweep voltammetry that uses a combined staircase potential and a square wave, which has the advantage of having better peak definition and location than conventional cyclic voltammetry or staircase voltammetry.The diagnostic test is performed to determine the electrolyte concentration of the sensor.Figure 2. Diagnostic TestingHow and when the End-of-Life and Predictive Calibration are flagged?The error and faults can be transmitted to the instrument every time it requests a gas reading from the sensor. For additional information about the gas reading format consult get data pack command (0x30) in the User’s Manual.Predictive Calibration alarm consists of two different parameters, and the • Thealarm will be triggered when either the countdown or the accuracy threshold are reached (whichever is triggered first):o The Predictive Calibration estimation will depend on the requested accuracy of the sensor. This parameter can be configured by the user: the tighter theaccuracy value, the more frequently the calibration.o Additionally, a countdown timer can be set by the user. This period can reflect the time required to calibrate the sensor, which may vary depending on thespecified standard or applications.• Likewise, the End-of-life is flagged when either the countdown or the future prediction algorithm conditions are met (whichever is triggered first):o The predicted End-of-Life algorithm is flagged when the sensor detects less than 50% of its initial sensitivity or when the electrolyte concentrationis above or below its limit. The sensitivity estimation is constantly updatedand its calculation is based on the measure at the minimum temperatures atwhich the sensor has been exposed to.o Along with this, there is a five-year countdown timer. The alarm is flagged after the sensor has reached its expected lifespan.How accurate are the End-of-life andPredictive Calibration functions?The predictive model for End-of-life and time to calibrationis highly accurate if the environmental conditions remainadequately constant.An analogy to this is the ETA (estimated time to arrival) in a car’s GPS system, which is based on previous average speed. If you travel at a constant speed, the ETA will count down linearly and be quite accurate over long distances. However, if you speed up or slow down the ETA could increase of decrease significantly throughout the journey. Similarly, if a sensor is kept in constant conditions, the future prediction based on historical conditions should predict a long way into the future quite accurately, and as a result the time to end of life or recalibration would decrease linearly over time. If the sensor is put into a more aggressive environment, then its predicted time to EOL/ recalibration will start to drop rapidly, whereas if a sensor that has been running in aggressive (e.g. dry) conditions is transferred to more benign conditions, the time to end of life or recalibration prediction may even increase over time.Other diagnostic tests:Just like the End-of-life and Predictive Calibration flags, the sensor can warn the instrument about other possible errors and failures that may appear on a sensor whenever a gas reading command is requested. These flags could also be used to indicate to the end user what type of maintenance is required, for example if the sensor warns that its electrolyte is getting too dry or wet the instrument could advise the user to store it in a suitable humidity environment to recover it.The following table shows the possible failures that the sensor may encounter along with their corresponding automatic detection methods:002717-2-EN | 2 | 08/21HoneywellAdvanced Sensing Technologies 830 East Arapaho Road Richardson, TX 75081FOR MORE INFORMATIONHoneywell Advanced Sensing Technol-ogies services its customers through a worldwide network of sales offices and distributors.

However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments and operation.When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.Cross Sensitivity TableToxic gases at TLV levels will have no cross-sensitivity effect on Oxygen CiTiceLs. At very high levels (i.e. percent levels), highly oxidising gases (e.g. ozone and chlorine) will interfere to the extent of their oxygen equivalent, but most other commonly occurring gases will have no effect. For example: Methane 100% 0 Hydrocarbons 100% 0 Hydrogen 100% < -2% Carbon monoxide 20% < -0.5%Acid gases such as CO 2 and SO 2 will be slightly absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of about 0.3% of signal per 1% CO 2. Capilliary controlled CiTiceLs (such as the 7OX/V) are not suitable for continuous operation in concentrations of CO 2 above 25%. In applications where high concentrations of CO 2 are present, the AO2 CiTiceL is recommended.The cross-sensitivity values quoted are based on tests conducted on a small number of sensors. They are intended to indicate sensor response to gases other than the target gas. Sensors may behave differently with changes in ambient conditions and any batch may show significant variation from the values quoted.Every effort has been made to ensure the accuracy of this document at the time of printing.

细孔和薄膜氧气传感器对对温度的变动都是敏感的,但敏感程度不同。 温度对细孔氧气传感器的影响相对较小,通常温度从+20°C 到–20°C 会导致输出信号 损失 10%。相对的,温度对薄膜氧气传感器的影响要大得多,气体扩散通过薄膜是一个活 动的过程,通常 10°C 的温度变化就会导致传感器信号输出加倍。薄膜氧气传感器要求 温度的相对稳定,因而许多 CiTiceLs?产品带有内置热敏电阻。 英国 CITY 氧气传感器典型应用：

英国CITY传感器（doc）
英国CITY英国CITY氧气传感器概况所有的氧气传感器都是自身供电,有限扩散,其金属-空气型电池由空气阴极,阳极和电解液组成。
（图一）氧气传感器简单来说是一个密封容器(金属的或塑料的容器),它里面包含有两个电极：阴极是涂有活性催化剂的一片PTFE(聚四氟乙烯),阳极是一个铅块。
这个密封容器只在顶部有一个毛细微孔,允许氧气通过进入工作电极。
两个电极通过集电器被连接到传感器表面突出的两个引脚,而传感器通过这两个触角被连接到所应用的设备上。
传感器内充满电解质溶液,使不同种离子得以在电极之间交换(参见图1)。
Figure 1 - Schematic of oxygen sensor.进入传感器的氧气的流速取决于传感器顶部的毛细微孔的大小。
当氧气到达工作电极时,它立刻被还原释放出氢氧根离子：O2 + 2H2O + 4e- " type="#_x0000_t75">4OH-这些氢氧根离子通过电解质到达阳极(铅),与铅发生氧化反应,生成对应的金属氧化物。
2Pb + 4OH- " type="#_x0000_t75">2PbO + 2H2O + 4e-上述两个反应发生生成电流,电流大小相应地取决于氧气反应速度(法拉第定律),可外接一只已知电阻来测量产生的电势差,这样就可以准确测量出氧气的浓度。
电化学反应中,铅极参与到氧化反应中,使得这些传感器具有一定的使用期限,一旦所有可利用的铅完全被氧化,传感器将停止运作。
通常氧气传感器的使用寿命为1-2 年,但也可以通过增加阳极铅的含量或限制接触阳极的氧气量来延长传感器的使用寿命。
毛细微孔氧传感器和分压氧传感器城市技术生产的氧气传感器根据进入传感器的氧气的扩散方式的不同分为两种,一种是在传感器顶部设有一毛细微孔,而另一种设有一层固体薄膜允许气体通过。
细孔传感器测量的是氧气浓度,而固体薄膜传感器测量的是氧气的分压。
