humidity and temperature measurement transducer | GHTU-...-MP
Product Description
general information:
The humidity transducer offers even greater possibilities to compensate the special sensor characteristics due to the newest microprocessor technology. Regarding precision, temperature stability and functionality a new dimension is entered. The transducer can be used for almost all applications due to the different types (e.g. wall or channel mount, with separated probe tube or with heat absorption hat) and the wide temperature range (electronic: -25°C to +50°C; sensor: -40°C to +120°C), 2 standard signal outputs.
- GHTU-1R-MP: wall version, probe length: 50 mm (standard version)
- GHTU-1K-MP: wall and duct version, probe length: 220 mm (standard version)
- GHTU-2K-MP: duct version, probe length: 220 mm (standard version)
- GHTU-SHUT-MP: heat absorption hat / weather protection
- GHTU-KABEL-MP: wall version with cable and high humidity sensor
| measuring range: |
relative humidity: 0.0 % to 100.0 % r.h. (temperature compensated) temperature: -40.0°C to +120.0°C or -40.0°F to +248°F |
| recommended humidity range: |
20.0 % to 80.0 % r. h. (standard) 5.0 % to 95.0 % r. h. (with option high humidtiy) |
| display options: | With option UNI an alternative display unit can be shown instead of the humidity measuring value. The unit selection is done via keyboard. wet bulb temperature: -27.0°C to +60.0°C dewpoint temperature: -40.0°C to +60.0°C enthalpy: -25.0 kJ/kg to +999.9 kJ/kg atmospheric humidity: 0.0 g/kg to 640.0 g/kg absolute humidity: 0.0 g/m3 to 200.0 g/m3 |
