HygroFlex HF5A Transmitter

Description

The Digital HygroFlex HF5A Advanced Humidity and Temperature Transmitters from Rotronic are ideal for applications where the exact measurement of humidity and temperature is required but additional monitoring is also needed for the values. 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
  • LED on front of housing, showing the operating status of the device
  • The analog output signals are monitored
  • LCD display for measured parameters, errors, alarms and operating status1
  • Digital version with RS485 digital Interface and Modbus RTU communication protocol3
  • Optional galvanic isolation of power supply and analogue outputs
  • Two analogue output signals, freely configurable and scalable
  • New housing, high immunity to dust and moisture within the device
