Transmitter series RHT-WM and RHT-DM incorporate the best humidity and temperature sensors with high accuracy and stability. They convert measured values into linear 4-20 mA signals, and an optional 0-10 Vdc output is available on request.
The microprocessor circuit allows complete configuration of the output range when used with the TxConfig PC interface and Windows® software. The humidity signal can be configured for relative humidity or dew point output. The RHT-WM model is dedicated to wall-mounted applications, while the RHT-DM version is suitable for duct and wall applications.
