The RHT-Climate WM is a humidity and temperature transmitter that provides high precision and stability of measurements, over a wide operation range, it calculates in real time seven psychrometric properties, all variables will be available by current or voltage retransmission The RHT-Climate WM is intended for Wall Mount.

What is exciting about the RHT Climate

The RHT Climate is packed with features that are found in RHT transmitters and controllers that cost 2 or 3 times the price.

Measured Parameters - The RHT Climate can be configured to display and retransmit the temperature and relative humidity values, or any of its psychrometric properties, calculated in real time:

  • Dew Point Temperature
  • Wet Bulb Temperature
  • Frost Point Temperature
  • Absolute Humidity
  • Specific Enthalpy
  • Partial Vapor Pressure
  • Mixing Ratio

Accuracy - Temperature ±0.2°C (0°C to + 60°C) Humidity ±1.8 %RH @ +23 °C (0 %RH to 90 %RH)

Analog OutputsTwo 0-10 V or 4-20 mA outputs configurable by software or front panel keypad

ModbusRS485 Modbus RTU communications configurable by software or front panel keypad

Alarm Outputs The RHT Climate has Two digital outputs and one embedded buzzer. The RHT Climate Transmitter allows for four options for its alarm outputs and for the buzzer:

  • Normal operation
  • Activation for set time
  • Delay in activation
  • Intermittent activation

The hysteresis value for each alarm and buzzer is configurable. This allows the RHT-Climate to be used as a standalone temperature and humidity controller.

LCD Display (Not on this model) - Using the keypad the operator can view temperature and humidity and all 7 psychrometric properties. The display will also show maximum and minimum values of temperature, humidity and Dew point temperature.

Configuration, Commissioning and Simulation - Versatile, the device allows configuration of parameters, simulation of temperature and humidity and generation of retransmission signal, useful features for commissioning on field in fast and easy way through USB with free PC software NXperience or directly by the keyboard.
