Description

Model WRHT-DM100 Wireless Duct Mount Relative Humidity Transmitter provides a license free 2.4 GHz wireless bridge between RH sensor and process instrument at a distance up to 1-mile line-of-site (LOS). The sensor/wireless transmitter combination accomplishes Humidity measurement by providing a 4-20 mA / 1-5V DC, or 0-5V DC output on the wireless receiver side that corresponds to the % Humidity measured by the sensor. Connect the receiver output to a process instrument or PLC.
