RHT-XS humidity and transmitter features a highly accurate and stable sensor for measuring relative humidity and temperature. The measured values are converted into 4 to 20 mA output signals which are linearly scaled to their readings.  The RHT-XS includes an electronics module and remote sensor.  The sensor is designed for non pressurized environments.

Configurable Parameters
The RHT-XS has several configurable parameters which are set by using the free downloadable software and the TxConfig-USB adapter. Configurable settings include:

  • Humidity or Dew Point Temperature - The RHT-XS can be configured to transmit either humidity or dew point temperature
  • Scalable Measurement Range/Output- Both the humidity and temperature measurement ranges are settable.  This allows you to optimize the 4-20mA output range.
  • Sensor Failure - Upon sensor failure the output may be set to go to either 4 mA or 20mA.
