Product Details
Thermal Conductivity Hydrogen Sensor KGD-ATRS-204
Product Introduction
The Thermal Conductivity Hydrogen Sensor KGD-ATRS-204 is a thermal
conductivity (TC) hydrogen sensor. By using the method of gas
thermal conductivity measurement, it realizes early and rapid
warning for the thermal runaway of automotive power batteries, the
energy storage of lithium batteries, and the application of
hydrogen energy, thus improving safety. At the same time, it can
effectively monitor hydrogen leakage and transmit the measurement
signals to the main control system through CAN communication. This
solution has remarkable features such as accurate measurement, fast
response time, large measurement range, low power consumption and
long service life.
Product Features- The measurement of H₂ adopts thermal conductivity technology (TC),
and the accuracy can reach ±(0.1%vol + 10% of the reading) within
the measurement range of 0~4%vol.
- The response time is fast, T80≤2s, and the service life can reach
15 years.
- The sensor adopts a mature automotive-grade circuit design and can
adapt to harsh in-vehicle and energy storage environments.
- CAN real-time communication, and the protection level can meet the
requirements of IP54.
