Reliable humidity and temperature measurement under extreme conditions up to 85 °C ambient temperature!

With the new generation of the HF5-Ex Rotronic offers transmitters for measuring in an even higher temperature range. The series is certified to ATEX and IECEx and therefore conforms to the latest international standards (IEC 60079-0/11/18/26/31/7).

The HF5-EX series consists of a robust aluminium transmitter with or without display. The attached probes are cast into a stainless steel tube, and are certified for operation in Zone 0/20. The transmitter itself is certified for Zone 1/21. “The new ATEX-Certificate allows measuring humidity and temperature in different temperature classes with exactly the same probe” says Daniel Barbeito Rial, Product Manager at Rotronic. “Using it up to +60 °C you have a temperature class T80°C respectively T5. Whereas using the probe up to +85 °C you have a temperature class T105°C respectively T4.”

The HygroFlex5-EX advantages at a glance:

  • Measurement of relative humidity and temperature, optional output of dew point and other calculated parameters
  • Safe operation in areas with explosion risk
  • Intrinsically safe electrical construction
  • No intrinsically safe power supply required
  • Interchangeable stainless steel probes
  • Robust aluminium housing
