Hydrogen pressure sensor: Hydrogen fuel is a new energy fuel mainly used in the electric vehicle industry. Hydrogen is not polluting, but it is flammable and explosive, and leakage must be prevented. Hydrogen is colorless and odorless, but detecting hydrogen leaks in the environment is challenging in many ways. At present, in order to be fully and safely applied to hydrogen-powered vehicles and related facilities, the intelligent hydrogen pressure sensor must be able to detect a very small amount of hydrogen in the air, and the speed of the hydrogen sensor must be fast enough to quickly detect hydrogen leakage before the fire. Learn about the application of intelligent hydrogen pressure sensors in the electric vehicle industry!

Hydrogen pressure sensorIn terms of safety and security, generally speaking, the car is equipped with a new energy management system, 32-bit dual-core vehicle controller powerful computing power and redundant safety design, you can safely use the industry's better vehicle control functions. In addition, the hydrogen ward, fuel cell engine room, hydrogen inlet room, passenger seat and other places on the car are equipped with high-sensitivity hydrogen sensors to detect hydrogen leakage. If an abnormality is detected, the reactor and hydrogen system will be automatically shut down immediately to ensure the safety of hydrogen for vehicles.

Hydrogen energy is a clean energy and a key area for the future development of new energy in China. In recent years, the development and utilization of hydrogen energy has been implemented, and major domestic automobile companies have carried out the research and development of hydrogen fuel cell electric vehicles. However, hydrogen is a very active flammable and explosive gas, and the development of hydrogen industry is far from hydrogen detection. Hydrogen station, hydrogen station, transport vehicle, hydrogen station also need to carry out hydrogen inspection. Taking a hydrogen fuel cell vehicle as an example, it is generally necessary to configure 3 to 5 hydrogen inspection modules. Therefore, with the development of the hydrogen energy industry, hydrogen sensors will usher in large-scale development and popularization. However, the current automotive specification-level hydrogen detection module has not yet been localized.

Hydrogen pressure sensorIt is basically manufactured by standard semiconductor technology. When the gas sensor is working, the temperature of the core detection area is between 200 and 500. Long-term high-temperature work puts forward higher requirements for the thermal stability of the detection material. When the catalytic combustion hydrogen pressure sensor encounters a high concentration of combustible gas during operation, the surface temperature of the hydrogen pressure sensor can reach more than 600 in an instant, so the high temperature impact resistance of the gas sensor is also a great test. The company's pre-developed nanomaterial batch printing technology combined with the creativity of the crystalline silicon process can print 4000 sensor chips on a 6-inch wafer at a time, greatly reducing sensor manufacturing costs and improving sensor performance consistency. The hydrogen sensor manufactured by the new material process can resist the high temperature impact caused by high concentration hydrogen, and has good stability in the high temperature and low temperature ring test.

The hydrogen pressure sensor is based on the imported sensor, and carries out signal amplification, data processing, intelligent operation and temperature and humidity compensation. In addition, after 99.999% purity standard gas calibration, will be sent to the customer. Therefore, after purchase, customers can directly collect standard signals for data processing without any operation.
