Wtsensor OEM Manufacturer Gold Platted Pressure Sensors for Hydrogen Application

Product Description

PC10AU Piezoresistive Silicon Pressure Sensor

Product overview 
PC10AU piezoresistive silicon pressure sensor is the core component of pressure sensor and pressure transmitter suitable for measuring hydrogen environment, can be easily amplified and assembled into a transmitter with standard signal output. It is protected from hydrogen penetration by diaphragm gilding.
Our company can also undertake special customization according to the needs of users, such as all-welded structure, wide temperature compensation, high reliable pressure sensors, especially for defense weapons equipment.

 

Product Description

Hydrogen penetration solution
Coating the base metal with a thin layer of gold protects the film from hydrogen penetration. The 99.9% pure gold coating (thickness of 3um) can eliminate hydrogen penetration without affecting the properties of the product itself.
