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 4-20 mA.

Using the digital communication interface TxConfig, the transmitter parameters can be configured to tailor a particular application.

The RHT-WM model is intended for wall mounting. The RHT-DM comes with a probe tip for duct mounting.

RHT-DM (Duct Mount) can be purchased with 150 mm and 250 mm probes

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
