Abstract

Abstract

The activation of catalyst combustion methane sensor is the key problem in the sensor’s usage.This paper validated the principle of catalyst combustion,analyzed the two-value problem of methane sensor.Aiming at the problems of activation and two-value,it designed a bridge circuit with constant temperature detection based on the impulse constant temperature power supply technology and close-loop feedback control system.It made good effect by experiment.
