VST temperature sensor
For alternative drive and storage systems
DESCRIPTION
The VST temperature sensor is used in applications that require a high degree of
flexibility and special adjustments. The compact design and use of media-specific
materials makes the VST ideal for use in applications with critical installation space
requirements and under harsh ambient conditions. The specially developed measurement
element not only guarantees fast response times, but also highly accurate results. The
sensors are available in a resistive configuration with an NTC element or PT100/ PT1000
element. As a transmitter version with a linearised, analogue output signal, the VST also
offers electrical protective and diagnostic functions, which are typical for the automotive
industry.
For the use in hydrogen applications, esp. for high-pressure tank systems with pressures
up to 900 bar, a pressure-tight and media resistant version is available.
