TRANSMITTERS FOR RH & TEMPERATURE

TRANSMITTERS FOR RH & TEMPERATURE

Probes for Relative Humidity
HYGROFLEX 4:
The new HygroFlex4 series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. Based on AirChip3000 technology, these precision instruments achieve a new level of accuracy in this category of product, and are more precise than the HF3 series.

The HygroFlex4 series offers maximum reproducibility and a system accuracy of ±1 %rh and ±0.2 K. The transmitters are available in wall and duct mount versions. Many useful functions can be activated with the optional HW4 software.

HYGROFLEX 5-EX:
The new HygroFlex5-EX series is the latest development in two-channel transmitters for the exact measurement of humidity and temperature in explosive atmospheres. This 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.

HYGROFLEX 7:
The HygroFlex7 series is equipped with sturdy metal housings and stainless steel probes for harsh industrial conditions. In common with other HygroFlex transmitters, the HF7 provides superb accuracy and reproducibity and comes in wall, cable and duct mount versions. Many useful features can be activated with the optional HW4 software, including in-transmitter logging, output scaling and self-diagnostics. Highly confi gurable via HW4 software
