催化燃烧式传感器失效与否的检测方法及所用检测装置
摘要：
本发明公开了一种催化燃烧式传感器失效与否的检测装置，包括温度传感器I(1)、温度传感器II(2)和控制组件(3)，控制组件(3)包括分别与电源模块(30)相连的采集模块I(31)、采集模块II(32)、中心控制器(34)和数据存储器(35)；温度传感器I(1)与采集模块I(31)相连，温度传感器II(2)与采集模块II(32)相连。本发明还同时公开了一种催化燃烧式传感器失效与否的检测方法：利用温度传感器I(1)和温度传感器II(2)分别感知工作状态中的待测催化燃烧式传感器的体表温度T1和所处的环境温度T2；根据公式λ＝ΔT/Δt得知待测催化燃烧式传感器的失效与否。采用本发明能有效检测出传感器是否失效。
摘要（英）：

The invention discloses a device for detecting the invalidation of a catalytic combustion type sensor, which comprises a temperature sensor I (1), a temperature sensor II (2) and a control assembly (3), wherein the control assembly comprises an acquiring module I (31), an acquiring module II (32), a center controller (34) and a data memory (35) which are respectively connected with a power supplymodule (30); the temperature sensor I (1) is connected with the acquiring module I (31), and the temperature sensor II (2) is connected with the acquiring module II (32). The invention also disclosesa method for detecting the invalidation of the catalytic combustion type sensor, which comprises the following steps of: respectively sensing the shell temperature T1 and the located ambient temperature T2 of the catalytic combustion type sensor to be detected in working state by the temperature sensor I (1) and the temperature sensor II (2); and obtaining the invalidation of the catalytic combustion type sensor to be detected according to the formula lambda=deltaT/deltat. The invention can effectively detect the invalidation of the sensor.
