This document is a user guide to the Rotronic AG HygroFlex HF5 humidity temperature transmitter. It covers the transmitter's overview, mechanical configurations and dimensions, general description, user configurable settings and functions, mechanical installation and electrical installation.
The HygroFlex HF5 transmitter series is designed for fixed installation in applications requiring high measurement accuracy. It works with any HygroClip 2 plug-in probe to measure relative humidity, temperature, dew point, or other psychrometric parameters. The system features interchangeable probes, digital signal processing within the probe, and user-configurable settings via HW4 software.
| Relative humidity accuracy | ± 0.8%RH |
|---|---|
| Temperature accuracy | 0.1ºC / 0.2ºF |
| Relative humidity range | 0...100%RH |
| Temperature range | -100 to 200°C |
The minimum supply voltage depends on the load resistance, calculated as V min = 10 V + (0.02 x Load).
Yes, using HW4 software, the HF5 can be configured to calculate dew point above and below freezing.
