催化燃烧氢气传感器的温度补偿研究

Study on temperature compensation of hydrogen sensor in catalytic combustion

对催化燃烧氢气传感器补偿元件在不同温度条件下的补偿效果进行实验研究和数据分析,发现补偿元件不能完全补偿温度变化对传感器输出的影响,导致传感器输出随温度变化而变化,使极限温度时测试误差大。针对该问题,提出了温度参数补偿方案,并进行了实验验证,发现温度补偿后传感器在极限温度的误差由6%FS减小到1.3%FS,极大地改善了传感器的测试误差,为传感器在不同环境温度下的准确使用提供了实验依据和合理的方案设计。

Experimental research and data analysis on compensation effect of compensation element of hydrogen sensor in catalytic combustion under different temperature conditions are carried out.It is found that the compensation element can not fully compensate for the influence of temperature change on sensor output,which results in sensor output changing with temperature change,which makes the test error at the extreme temperature is large.Aiming at this problem,a temperature parameter compensation scheme is proposed,and is verified by experiments.It is found that the error of the sensor in limit temperature after temperature compensation is reduced from 6%FS to 1.3%FS,which greatly improves test error of sensor,and provides experimental basis and reasonable scheme design for accurate usage of sensor in different ambient temperatures.
