Product Description

The new HygroFlex5-EX series is the latest development in two-channel transmitters for exact measurement of humidity and temperature in explosive atmospheres. This measuring device conforms to the latest international standards. 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 intelligent design of the circuitry with electrical isolation permits the measuring system to be operated without an intrinsically safe power supply.

Reliable Measurements Under Extreme Conditions :

  • 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

Functional display :

  • Measurement values with trend indicator
  • Conguration via keyboard possible

Proven housing :

  • Robust, reliable aluminium housing
  • Protection class IP66
  • Wall or duct mount possible

Power supply :

  • 1028 VDC
  • No intrinsically safe power supply required

Outputs :

  • The two analogue outputs can be freely selected and scaled
  • 2-wire (2 x 4...20 mA)

Exchangeable probes :

  • Different probes can be connected for different applications
  • Simple calibration of the probes outside the explosive zone
  • Explosion protection classes (gas and dust)

Transmitter:

  • II 2(1) G Ex eb mb [ia Ga] IIC T5 Gb
  • II 2(1) D Ex tb [ia Ga] IIIC T80C Db

Probes:

  • II 1/2 G Ex ia IIC T5 Ga/Gb
  • II 1/2 D Ex ia IIIC T80oC Da/Db

Simple configuration :

  • The conguration can be specied directly when ordering
  • Later conguration on site is also possible, using the HW4 software
