Freeze-Proof Pressure Sensor

For both airless and air-assisted SCR systems, we offer our customers freeze-proof sensors.


The pressure sensor is a media-stable, ceramic, pressure measuring cell which converts pressure variations to electrical signals. The electrical output signal is processed by an internal ASIC. This sensor has been developed with specially patented technologies to withstand higher pressures during freezing.

Typical applications

This sensor was developed especially for use in liquids which are susceptible to frost.

Special features
  • Special patented design
  • Integrated freeze protection
  • Resistant to media thanks to stainless steel housing

Exhaust After Treatment

Exhaust technology is one of our core competencies and we have several years of experience in mass production for EURO4 and EURO5 as well as Tier4i and f engines.

Products such as high-temperature sensors with integrated electronics, freeze-proof pressure sensors and AdBlue quality sensors are increasingly powerful and offer excellent cost-benefit ratios, which are among the applications of leading OEMs in the transportation segment.
