Product Description

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. 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.
