Wall-Mounted Temperature and Humidity Sensor 4 to 20 mA output
The RHT-WM transmitters feature highly precise and stable sensors for measuring relative humidity and temperature. These measurements are converted into 4 to 20 mA output signals, which are linearly proportional to the readings.
The RHT-WM transmitters feature highly precise and stable sensors for measuring relative humidity and temperature. These measurements are converted into 4 to 20 mA output signals, which are linearly proportional to the readings.
As microprocessor-based devices, they can be configured using the TxConfig-USB communication interface along with the SigNow app or software, available for Android and Windows. The outputs can be customized to transmit temperature, relative humidity, or dew point data. The RHT-WM model is designed for wall mounting, while the RHT-DM model includes an extended sensor probe for installation in ducts or through walls.
Taking Care with Sensors
The RHT-WM is primarily designed for commercial offices and buildings where the air is relatively clean and condensation is not a concern. The calibration of the humidity sensor may be altered if it is exposed to contaminant vapors or extreme humidity and temperature conditions over extended periods. For use in dusty environments, it is recommended to use a Sintered Bronze Dust Cover (SKU RHT-030).
