Automotive hydrogen pressure sensor online sale

Product description

Hydrogen pressure sensors: Optical hydrogen pressure sensors take advantage of the optical properties of gases. According to the different working principle, it can be divided into optical fiber Hydrogen Pressure Sensor, surface acoustic hydrogen Pressure Sensor and optical acoustic hydrogen pressure sensor. The principle of fiber optic hydrogen pressure sensor is to use the combination of fiber and hydrogen sensitive material, so that the hydrogen sensitive material and hydrogen reaction, change the physical properties of the fiber, so as to change the optical properties of the light transmitted in the fiber. Hydrogen concentration is measured by detecting changes in physical quantities corresponding to the output light. According to different sensing mechanisms, fiber optic hydrogen pressure sensors can be divided into microlens type, interference type, evanescent field type and fiber Bragg grating type. In the field of industrial control, hydrogen sensors are used to monitor hydrogen concentration, such as processing of fossil or rocket fuels, synthesis of ammonia and methanol, etc. Early warning and monitoring of hydrogen leaks are also essential in the nuclear reactor, power generation and communications industries. The key to these applications is also to keep the hydrogen concentration below the set combustible concentration. Specializing in the manufacture of intake manifold Absolute Pressure Transmitter, Hydrogen Energy Pressure Sensor, engineering hydraulic sensor, injection molding machine special Pressure Transmitter.
