Reliable humidity and temperature values are easier to trust when the transmitter is built for the installation point. GHTU variants cover wall and duct mounting, separated probe installation and open-air measurement with the optional heat absorption hat, helping you use the same product family across indoor, duct and weather-exposed tasks.
The measuring core covers 0.0 ... 100.0 % RH with automatic temperature compensation and sensor temperatures from -40.0 ... +120.0 °C. Accuracy at 25 °C in the recommended range is ±2.5 % RH and ±0.4 % of measuring value ±0.2 °C, giving operators a clear basis for monitoring and control decisions.
Commissioning stays practical on site. The transducer provides a 4-20 mA standard output, selectable voltage options, a 4-digit LCD display, min/max memory, adjustable offset and slope, and scalable output signals. The ABS housing and EN 175301-803/A elbow-type plug are rated IP65 for industrial environments.
The 4-digit LCD display alternates between humidity and temperature. With option UNI, an alternative value can be shown instead of humidity, including wet bulb temperature, dewpoint temperature, enthalpy, atmospheric humidity or absolute humidity.
The family includes wall, surface/duct and duct designs. The cable version uses a separated sensor tube connected to the device via a 1 m teflon cable and includes the high humidity sensor option.
Fitting lengths are available for 50 mm, 220 mm, 300 mm, 400 mm and 500 mm sensor tubes, with 50 mm standard for surface design and 220 mm standard for surface/duct and duct designs.
The auxiliary energy is 12 ... 30 VDC, or 18 ... 30 VDC for 0-10 V output. Reverse voltage protection is specified at 50 V permanently.
Standard and high humidity sensor options are listed. An encapsulated PC board option is available for applications with condensation risk caused by temperature changes.
