The RHT-P10 and RHT-XS transmitter series incorporate the best high accuracy and great stability relative humidity and temperature sensors. They convert the measured values into linear 4 to 20 mA signals. The microprocessor based circuit enables full configuration of output range when used with the TxConfig PC interface and the Windows® based software.
RHT-P10 model is aimed at humidity and temperature monitoring in pressurized or vacuum systems. Sensor probe in Stainless Steel can be thread mounted in the supplied flange* or directly to the system wall or pipe.
RHT-XS is aimed at humidity and temperature monitoring in non-pressurized systems that require a remote sensor.
*The flange is not attached to the transmitter and must be purchased separately.
- Humidity measurement
Measuring range: Configurable between 0 and 100 % RH or -100 and 103 °C for dew point;
Response time (1/e (63 %)): 8 seconds @ 25 °C (is slow moving air 1 m/s).
- Temperature measurement
Total accuracy: Configurable between -40 and 120 °C;
Response time (1/e (63 %)): up to 30 s (is slow moving air 1 m/s).
- Power supply
