Rotronic  is proud to announce the introduction of a new series of Intrinsically Safe sensors and measurement transmitters, suitable for installation in areas where there is a risk of explosion due to the presence of dust or gas in the environment. Designed for the pharmaceutical, biotechnology, grain & sugar, petrochemical, and oil & gas industries.

Conforming to the latest international standards, the HygroFlex5-EX measurement transmitter is galvanically isolated, there is no need for an intrinsically safe power supply, dedicated ‘clean’ earth or a Zener barrier. The stainless steel probe selected for the application from the range available is rapidly interchangeable, no calibration adjustment required.

Significant advantages of the Rotronic ATEX humidity & temperature sensors:

  • Interchangeable stainless steel probes certified for operation in Zone 0/20
  • Standard & cable mount probes, screw-in probe for applications at pressure
  • HygroFlex5-EX measurement transmitter certified for Zone 1/21
  • No intrinsically safe power supply required; galvanically separated
  • Wall and duct versions of the measurement  transmitter available
  • 2-wire supply, 2-analogue outputs (inc. dew point, g/kg & moisture values)
  • Robust aluminium transmitter housing; IP66 protection
  • LC display option with trend indicators. Keypad for configuration
  • Service interface (USB) for configuration using HW4 (outside explosion zone)
  • Range of calibration accessories available (for use outside the explosion zone)
