HygroFlex HF5A Transmitter

Description

The 2-Wire HygroFlex HF5A Advanced Humidity and Temperature Transmitters with display from Rotronic are ideal for applications where the exact measurement of humidity and temperature is required in rooms. The HF5A can also provide Psychrometric calculations, eg. Dew Point, etc. The HF5A is a direct replacement for the older HygroFlex HF5 Transmitter

Applications

  • Humidity and Temperature Monitoring
  • Environmental Condition Monitoring in HVAC Applications
  • Temperature and Humidity Monitoring in the Chemical Industries
  • Production Conditions in Food and Pharmaceutical Industries
  • Printing and Paper Industries
  • Agriculture & Meteorology
  • Storage Condition Monitoring in Archaeology
  • Measurement in Cheese Production and Storage
  • Controlled Atmosphere Monitoring
  • Coating Process Optimisation
  • Vehicle Spraying Facility Condition Monitoring

Features

  • Interchangeable, plug-in HygroClip2 Advanced probe (sold separately)
  • Probe separation: Up to 5m/16.4ft (50m/165ft with a digital signal booster)
  • Relative humidity, temperature, dew point parameter
  • High transmission accuracy and long-term stability
  • NFC-Interface for communication with the device
  • Firmware updates over NFC-Interface and HygroSoft Software
  • The analog output signals are monitored
  • LCD display for measured parameters, errors, alarms and operating status
  • Galvanic isolation of power supply and analog outputs
  • LED on front of housing, showing the operating status of the device
  • Two analog output signals, freely configurable and scalable via HygroSoft Software
  • Housing features high immunity to dust and moisture within the device
