New technique for the stability of the zero-point of catalytic sensor

摘要

The zero-point drift of catalytic sensor could increase the error of detecting methane in mine. The high stability of the zero-point drift of the sensor is very important for the reliability. The catalytic sensor is made of detecting component and compensating component and the consistency of the two components is related to the stability of the sensor. The new matching technique of compensating component and detecting component, the process of dynamic parameters, could much improve the zero-point stability of the catalytic sensor.
