Thermal Conductivity Hydrogen Sensor KGD - ATRS - 313
Product Introduction
The KGD - ATRS - 313 thermal conductivity hydrogen sensor is a hydrogen sensor based on thermal conductivity (TC) technology. It uses the method of gas thermal conductivity measurement to achieve early and rapid warning for the thermal runaway of automotive power batteries, lithium - battery energy storage, and hydrogen energy applications, thereby improving safety. Meanwhile, it can effectively monitor hydrogen leakage and transmit the measurement signals to the main control system through CAN communication. This solution features accurate measurement, fast response time, wide measuring range, low power consumption, and long service life.
Product Features
- For H₂ measurement, thermal conductivity technology (TC) is adopted, with an accuracy of ±(0.1%vol + 10% of the reading) within the measuring range of 0 - 4%vol.
- Fast response time with T80 ≤ 2s, and a service life of up to 15 years.
- The sensor adopts a vehicle - grade mature circuit design, enabling it to adapt to harsh in - vehicle and energy - storage environments.
- CAN real - time communication, and the protection level meets the requirements of IP54.
