Features
SS151 series piezoresistive pressure transducers are mainly used for measuring hydrogen gas. Gold plating on stainless steel prevents hydrogen gas from entering. This prevents brittleness and maintains the metal’s toughness. The transducers’ pressure ranges from 35 KPa to 60 MPa.
Several million of these pressure transducers are in use worldwide across various applications.
Main fields of application include:
- Process control systems
- Hydraulic systems and valves
- Hydrogen measurement
- Hydrogen vehicles
