product details

This gas sensor uses a highly sensitive chemical principle to detect toxic and harmful gases generated by thermal runaway combustion caused by internal short circuits, overcharging, overdischarging, and collisions in power batteries, as well as the oxidation-reduction reaction between combustible gases and oxygen to form current signals. It can achieve early detection, intelligent judgment, and early warning of battery fires, maximizing the protection of the personal safety of electric vehicles and passenger drivers, and opening up a life passage for the evacuation of drivers and customers.

Sensor characteristics

High sensitivity, capable of detecting trace gas components emitted by batteries during the initial stage of thermal runaway, achieving early detection of fires;

Zero power consumption, using current type signal output, the sensor itself has no power consumption, realizing detection during battery sleep;

Strong anti-interference ability, strong selectivity for the measured gas, and will not be affected by dust interference;

Excellent repeatability and stability, with a small range of testing errors for the same concentration.

Main applications

This sensor is widely used in the fields of battery detection and fire safety, especially for fire warning and detection of flammable, explosive, toxic and harmful parts such as battery compartments and batteries in new energy electric vehicles and hybrid electric vehicles that are not easy to observe or directly approach. It provides the most critical judgment basis for battery leakage and explosion.
