Compact humidity and temperature sensor for use in extreme conditions

  • for measuring relative humidity and temperature
  • with capacitve Mela® humidity sensing element
  • with current or voltage output
  • compact sensor in a high-grade steel housing
  • IP 65 protection

General information

• Humidity ±2% rh  (5...95 %rh at 10...40 °C)
• Temperature
± 0,2 K with voltage output
± 0,2 K - 0,6 K with current output

The sensors of the VC and VR series are rod-shaped, compact sensors. They can be used in a wide range of applications and have been specially developed for use in extreme conditions. Their design also makes them ideally suited for performing equilibrium humidity measurements in bulk materials and in brickwork.
