Key parameters
Type
Rotronic HygroFlex5 (HF5) humidity and temperature transmitter for wall or duct mounting
Measurements
Relative humidity, temperature, and dew point via interchangeable HygroClip2 / HC2A probes
Outputs
Two freely programmable/scalable analog outputs; HF52 2-wire, HF53 3/4-wire, HF54/HF56 galvanically isolated versions
Digital
Optional RS-485, Ethernet, and wireless networking alongside analog outputs
Power
15-40 VDC / 12-28 VAC; isolated 9-36 VDC / 7-24 VAC; or 100-240 VAC isolated options
Housing
Industrial-quality housing for wall or duct use; optional backlit graphic display variants
Fits wall or duct humidity control where you need a HygroFlex5 HF5 transmitter with interchangeable HygroClip2/HC2A probes and freely scalable analog outputs.
Key advantages
- Measurements — Relative humidity, temperature, and dew point via HygroClip2 / HC2A probes
- Outputs — Two freely programmable/scalable analog outputs; HF52 2-wire; HF53 3/4-wire; HF54/HF56 isolated
- Digital — Optional RS-485, Ethernet, and wireless networking
- Power — 15–40 VDC / 12–28 VAC; isolated and 100–240 VAC options
- Housing — Industrial wall/duct housing; optional backlit graphic display
Typical applications
- HVAC humidity control.
- Food, pharmaceutical, printing, and paper humidity monitoring.
- Sites needing interchangeable probes and simulators for validation.
Selection guide
- Variant — HF52/HF53/HF54/HF56 wiring and isolation
- Probe — HygroClip2/HC2A model for range/accuracy
- Display / digital — Graphic display; RS-485/Ethernet/wireless
- Mounting — Wall vs duct
Common mistakes
- Ordering transmitter without the HygroClip probe.
- Mismatching 2-wire vs 3/4-wire power topology.
- Ignoring probe interchange/simulator needs for validation.
When to RFQ / what to tell us
- HF5 variant, probe model, wall vs duct.
- Analog scaling; digital options; display.
- Quantity and ship-to.
