Rotronic HF320-D-B Humidity and Temperature Transmitter, Duct Mount

Measures Humidity and Temperature, Duct Mount 2-wire (loop powered), 10 to 28VDC, 4...20mA

In combination with advances in sensor technology and integration, the Rotronic HygroFlex3-series provides superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurements to a whole new level of performance and reliability (less than 2 %rh / 0.3 K).

The Rotronic HygroFlex3-series is highly flexible with two freely selectable and scalable analog outputs. The analog outputs are assignable to relative humidity, temperature or dew point with 2-wire or 3/4-wire systems. Two integrated relay contacts are available to convert the transmitter to a thermostat / hygrostat. Thanks to the high long-term stability of the sensors and auto- diagnostics, the transmitters are both service-friendly and reliable and will save you time and money.

AirChip3000 Technology
AirChip3000 technology compensates humidity and temperature over 30,000 reference points, has a 2000 data point memory, calculates dew/frost point, has sensor auto-diagnostics and automatic correction. AirChip3000 also includes active alarming and information, as well as ASIC (Application Specific Integrated Circuit); micro-controller and EEPROM on one chip.

Rotronic HygroFlex3-series Outputs
The highly flexible HygroFlex3-series allows the user to freely select the analog outputs by entering the type of output signal and scale. Switch actuation points for relative humidity and temperature are easily set using a potentiometer for the relay outputs option.

Rotronic HygroFlex3-series Applications
The HygroFlex3-series transmitter is ideal for all applications where exact humidity and temperature measurement is critical. The transmitters can be used in a variety of fields including:

  • Heating, ventilation, air conditioning
  • Greenhouses
  • Museums
  • Warehouses
  • Libraries
  • Railway stations
  • Climate control in office buildings
Calibration Lab
