GRHU...MP, Air Humidity Transducer

The newest generation of humidity/temperature 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 used for almost all applications due to the different types (e.g. wall or channel mount, with separated probe or with heat absorption hat) and the wide temperature range (electronic: -25°C...+50°C; sensor: -40...+120°C).

with/without on-site display
output ranges freely scalable
adjustment by operator possible
output signals for humidity are electrically isolated
available output signals: 4-20 mA, 0-1 V or 0-10 V

Technical data:

Measuring ranges:
Humidity: 0,0 ... 100,0%RH (temperature compensated)
Recommended humidty range: 20,0 ... 80,0%RH (standard)
                                                          5,0 ... 95,0%RH (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 will be done via the interface or at the keyboard.
Atmospheric humidity: 0,0 ... 640,0 g/kg
Absolute humidity: 0,0 ... 200,0 g/m³
Accuracy: (at 25°C and in recommended range)
            Display: humidity ±2,5%RH
            Add. output signal: each ±0,2% FS
Temperature compensation: automatically
Output signal: 1 x 4-20mA (2-wire), freely scalable
                           option: 0-1V, 0-10V (other output signals upon request)
Connection: 4 - 20 mA (2-wire)

for option AV01, AV10: 0 - 1 (10) VDC (3-wire)

for option AV01G, AV10G: 0 - 1 (10) VDC (3- or 4-wire)
Auxiliary energy: 12 ... 30 VDC or 18 ... 30 VDC (for output 0-10 V)
Reverse voltage protection: 50V, permanently
Perm. impedance (at 4-20mA): RA [O] = (Uv [V] - 12V) / 0,02 A
Permissible load (at 0-1(10)V): RL [O] > 3000 O
Display: approx. 10 mm high, 4-digit LCD-display, alternating humidity and temperature display
Working temperature: -25 to 50 °C (electronics)
Sensor head and tube: -40 to 100 °C - for short time up to 120°C
Storage temperature: -25 to 70°C
Relative humidity (electronic): 0 to 95%RH (non-condensing)
If there is a risk of condensation due to temperature changes, please use our encapsulated or lacquered types (optionally available).
