H2-Low Pressure Sensor LPS

For fuel cell systems

Our low pressure sensor LPS was specially developed for use in hydrogen (H2) applications, such as fuel cells.

With its variants for pressure ranges up to 6 bar, the sensor is designed for measuring low pressures 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. For an optimal integration in systems, the sensor is available with analog or digital (SENT) output signal.
