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)。

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。

The thermistor gives the AO2 a very stable output over a wide temperature range.The graph below shows the typical output behaviour of AO2 sensors over the range 0°C to +40°C.Cross-sensitivityThe AO2 has been tested for cross-sensitivity to a number of gases likely to be present in an automotive exhaust sample. The gas concentrations used and the response of the AO2 have been summarised below.These figures show that of the gases tested none show a sufficiently large cross-sensitivity to cause any inaccuracy in readings. In addition the baseline was unaffected by exposure to these gases.Every effort has been made to ensure the accuracy of this document at the time of printing.

Every effort has been made to ensure the accuracy of this document at the time of printing. In accordance with the company’s policy of continued product improve-ment City Technology Limited reserves the right to make product changes without notice. No liability is accepted for any consequential losses, injury or damage resulting from the use of this document or from any omissions or errors herein. The data is given for guidance only.

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 Behaviour
1) Gradual changes
The 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 fluctuations
A 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 away
Linearity
The 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 NOTE
This 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.
