CMV-2021D catalytic hydrogen sensor adopts MEMS process, works according to the principle of catalytic combustion effect, and is paired by a detection element and a compensation element to form an arm of the bridge, when the resistance of the detection element increases, the output voltage of the bridge changes, the voltage variable increases proportionally with the increase of hydrogen concentration, and the compensation element plays a reference and temperature and humidity compensation role.

Application

Hydrogen-powered vehicle
Hydrogen energy preparation
Energy storage battery / power station
Hydrogen energy transport and use
Hydrogen detection in other scenarios

Features

The bridge output is linear
Quick response
