HygroFlex HF5A Transmitter

Description

The 2-Wire HygroFlex HF5A Advanced Humidity and Temperature Transmitters from Rotronic are ideal for applications where the exact measurement of humidity and temperature is required in rooms. 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 or other psychrometric 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
  • 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
  • New housing, high immunity to dust and moisture within the device
