The 4012A absolute pressure sensor from Kistler delivers reliable measurements that are essential for optimizing hydrogen-fueled combustion engines, and for pressure monitoring in fuel cells. With a design developed for use in H2 environments, this sensor features a proven high resilience to hydrogen.
The 4012A hydrogen pressure sensor can be used for gas exchange analysis, as well as pressure measurement in the low-pressure fuel supply rail of hydrogen engines. The sensor can be used to monitor hydrogen pressure in the low-pressure range of a fuel cell. To do this, the piezoresistive absolute pressure sensor features two measuring ranges: up to 20 bar and 50 bar.
