The RHT-WM and RHT-DM transmitter series incorporate the best high accuracy and great stability relative humidity and temperature sensors. They convert the measured values into linear 4 to 20 mA signals and optional 0 to 10 Vdc output can also be offered under request.
The microprocessor based circuit enables full configuration of output range when used with the TxConfig PC interface and the Windows® based software.
The humidity signal can be configured to either relative humidity or dew point output.
The RHT-WM model is dedicated to wall mounted applications and the RHT-DM version is suitable for duct and through-the-wall applications.

  • Power: from 12 Vdc to 30 Vdc (model 4-20 mA) or 18 to 30 Vdc (model 0-10 V)

  • Output

    • Two-wire loop powered  4-20 mA or 20-4 mA

    • Voltage output: 0-10 Vdc (optional)



  • Isolation between outputs

    • Isolated 4-20 mA outputs

    • Non-isolated  0-10 Vdc outputs



  • Output load (RL)

    • Model 4-20 mA: RL (max. in Ohms) = (Vdc – 12) / 0.02

        where: Vdc=power voltage in Volts

    • Model 0-10Vdc: 10 Kohms Minimum



  • Internal protection against reversed voltage wire polarity

  • Cable input: PG7 cable gland

  • Operational Limits
    • Electronic Module: -10 to +65°C, 0 to 95%RH
