Options

  • Pressure-resistant up to 25 bar

Compact sensors with robust head in the stainless steel casing can be employed up to 25 bar or up to 10 bar with ball valve. All sensors in this series are equipped as standard with
equipped with a ZE 13 stainless steel sintered filter as standard.

The humidity and temperature values are output via two analogue current or voltage outputs.

Type VR is pressure-resistant up to 10 bar (with a ball valve)
Type VR.D is pressure-resistant up to 25 bar

They have been specially developed for harsh operating conditions. Sensors are used to measure the relative humidity or the relative humidity and temperature in air and other
non-aggressive gases.

Capacitive MELA® sensorchips
Equipped with the highly dynamic capacitive MELA® sensor element, the sensor provides reliable performance across the full humidity range. Using the MELA® sensor element ensures long-term stability, resistance to dew formation, minimal hysteresis, and strong dynamic capabilities.
