H2-Medium Pressure Sensor MPS

For medium pressure applications

Our medium pressure sensor MPS was specially developed for use in hydrogen (H2) applications, such as fuel cells and pressure regulators.

The sensor, with its variants for the different pressure ranges up to 30 bar, is designed for measuring pressure in stationary and mobile applications.

Materials that come into contact with fluids have been selected in accordance with the requirements for use with hydrogen and withstand the high stresses of use in hydrogen environments, even over long service lives. Although not required by law, the sensors are EC79 and HGV 3.1 tested.

For an optimal integration in systems, the sensor is available with analog or digital (SENT/LIN) output signal.
