VST temperature sensor

For medium pressure applications and fuel cell systems

The VST temperature sensor is used in applications where extremly fast response times are required, while still ensuring media compatibility.

Due to the compact design and the use of media-specific materials, the VST achieves excellent results in applications where space is critical, as well as under harsh environmental conditions. The specially developed measuring element not only ensures fast response times but also a high degree of accuracy.

The transmitter version of the VST with a linearised, analog output signal also offers the electrical protection and diagnostic functions typical to the automotive industry.
