    Description

    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: -25C...+50C; sensor: -40...+120C).
    • 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/m
    Accuracy: (at 25C 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 120C
    Storage temperature: -25 to 70C
    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).
    Housing: ABS (IP65)
    Sensor tube: tube 14 mm , with screw-type protection cap
    Sensor length: 50 mm (...1R) or 220 mm (...1K, ...2K)
    option: 300 mm, 400 mm, 500 mm
    Electric connection: elbow-type plug acc. to EN 175301-803/A (IP65),
    Mounting: 4 housing holes for wall mounting or by means of plastic tube clamps for duct mounting
    Functions: min-/max-value memory, offset and slope adjustable, output signal scalable
    The transducers are available in 3 variants:
