H2-High Pressure Sensor HPS
For high pressure applications and tank systems
Our high pressure sensor HPS was specially designed for the use in hydrogen (H2) applications, such as filling stations and high pressure tanks, as well as measuring and testing technology.
Our HPS sensors are designed for the two nominal pressure ranges of 0 to 500 bar and 0 to 900 bar for measuring system and tank pressure in stationary or 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. The HPS sensors are certified according to the H2 norms EC79 and HGV 3.1.
For an optimal integration in systems, the sensor is available with analog or digital (SENT/ LIN) output signal.
