New RHT-DM Duct Mounted Humidity, Dew Point and Temperature Transmitter

Overview

The RHT-DM duct mounted temperature and humidity transmitters incorporate the best high accuracy and great stability relative humidity and temperature sensors. The RHT-DM convert the measured values into linear 4 to 20 mA signals or optionally 0 to 10 Vdc output. The microprocessor based circuit enables full configuration of output range when used with the optional TxConfig PC interface and the Windows® based software. The humidity signal can be configured to either relative humidity or dew point output.
