Vehicle Hydrogen Gas Leakage Detection Module ZC61

  • ZC61.png


ZC61 hydrogen leakage sensor is mainly used in the monitoring of hydrogen leakage in the hydrogen fuel cell engine and hydrogen supply pipeline system. The catalytic combustion sensor of the MEMS process is used to detect the hydrogen concentration. This sensor is a high -performance module made by closely combining mature detection technology with high-quality design circuits.

Mainly application:
Hydrogen energy vehicles, hydrogen energy preparation, hydrogen energy storage, and hydrogen energy transportation.


* MEMS process
* Intelligent algorithms
* Anti-electromagnetic interference
* CAN interface output
* Excellent repeatability and stability
* Long service life

Vehicle Gas Leak Alarm

Cars using natural gas as fuel can save nearly half of the cost. Driven by economic interests, most taxi drivers tend to switch to natural gas cars. It is understood that the main reason for the explosion of the natural gas vehicle is the quality and stability of the gas cylinder. In most cities, there are no qualified manufacturers for modification or formal inspection agencies for natural gas compression cylinders for taxis, but the number of modified gas taxis is increasing day by day. Natural gas vehicles travel through the streets of the urban, with great fluidity and instability, and there are considerable hidden dangers.
