ATEX certified humidity & temperature sensors

They were developed 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).

• Sensor alarm – humidity & temperature can be set to fail high. 

• 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).
