Hydrogen propulsion is the future of environmentally friendly commercial vehicles and buses, because hydrogen serves as an energy source for internal-combustion engines or for fuel cells connected to electric drives. The hydrogen is typically stored in tanks under extreme pressure, which must be controlled very precisely – this is where our special hydrogen pressure sensors come into play. We supply robust sensors for tank and fuel-cell applications. Our hydrogen-compatible pressure and temperature sensors are specifically designed to withstand the harsh conditions in hydrogen environments. The sensors operate in the low- to high-pressure range and have a robust design. A sensor is specifically designed to provide accurate measurements even if water freezes on the sensor membrane. We develop sensors in accordance with ASIL A and ASIL B, and offer different output signals for each sensor. Our hydrogen sensors are certified according to EC79 and HGV 3.1.
Sensor systems for Hydrogen applications
VST temperature sensor
For alternative drive and storage systems
The VST temperature sensor is used in applications where a high degree of flexibility and specific adaptations are required. Due to the compact design and the use of fluid-specific materials, the VST achieves excellent results in applications where space is critical, as well as under harsh environmental conditions.
LPS, MPS, HPS hydrogen pressure sensors
For hydrogen systems and tanks
Our LPS, MPS and HPS pressure sensors were specially developed for scenarios involving the fluid hydrogen (H2) and are used, for example, in fuel cells, filling stations and high-pressure tanks.
Our climate-pressure sensors are installed in air-conditioning systems for temperature regulation. Climate-control pressure transmitters (CCTs) have been specifically developed for measuring pressure in vehicle refrigerant lines. Thanks to a robust aluminium housing, these sensors offer a cost-effective solution for vehicle air-conditioning systems.
Our OPS, VSP or IPT pressure sensors are used to measure the oil pressure in the transmission. The air pressure in the unit is measured with our pressure sensor. The special feature of our sensors is that they are robustly designed to withstand the stresses of oil-pressure applications.
Our intelligent sensor systems are also used in motorsports. Whether exposed to the pressure in the transmission or clutch, or to temperature in the tank – our sensors are robust, measure precisely and put the emphasis on performance!
