The Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM are microprocessor based instruments that incorporate high accurate and stable sensors whose information is converted to linear 4 to 20 mA. The RHT-WM is intended for Wall Mount.

Using the digital communication interface TxConfig (see SIG-008), the transmitter parameters can be configured to tailor a particular application.

Taking Care with Sensors

The RHT-WM is designed primarily for commercial offices and building where air is relatively clean and condensation does not occur. The calibration of the humidity sensor may be changed if it is exposed to contaminant vapors or extreme humidity and temperature conditions for long time periods. If using in a dusty environment a Sintered Bronze Dust Cover (SKU RHT-030)is recommended
