Applicability:
This manual applies to the following HF5 series transmitters:
2-wire loop powered models (HF52) with firmware version 1.6
All other models with firmware version 2.x, where 2.x can be 2.0, 2.1, etc.
Changes to the last digit of the version number reflect minor firmware changes that do not affect the manner in
which the instrument should be operated.
1 Overview
The HygroFlex HF5 transmitter series is designed for fixed installation in applications where high
measurement accuracy is required and can be used with any of the HygroClip 2 plug-in probes.
The wide assortment of HygroClip 2 humidity-temperature probes can meet almost any application
requirement. The HygroClip 2 probes feature well proven, durable sensors. Digital signal processing within the
probe ensures consistent product performance and also facilitates the task of field maintenance with features
such as potentiometer-free calibration, hot-swapping of the probe, etc.
Main features of the HF5 series:
Interchangeable, plug-in HygroClip 2 probe (sold separately)
Probe separation: up to 5 m / 16.4 ft (100 m / 330 ft with a digital signal booster)
Relative humidity, temperature, dew point or other psychrometric parameter
0...100%RH and -100 to 200°C (-148 to 392°F) - depending on probe model
Accuracy: ± 0.8%RH and 0.1ºC / 0.2ºF
Analog outputs only, analog and digital outputs combined or digital outputs only
User configurable settings
