Calibration-Free,2%Or 3%Accuracy,Optional Display

 

Demanding humidity/temperature applications require the Series RH/RHL Transmitter which offers high accuracy,long term stability,and reliable operation.The Series RH/RHL is designed for monitoring and controlling humidity or both humidity and temperature in building energy management systems,HVAC,commercial,residential,clean rooms,museums,climate chambers,and other space monitoring applications.

The Series RH/RHL is a two-wire transmitter with a 4-20 mA loop powered output or 0 to 10 VDC output.The state of the art sensor recovers from 100%saturation and is calibration-free.A variety of mounting configurations are available including wall mount,duct mount,and OSA (outside air)models.Select humidity monitoring or humidity and temperature models.

The combined humidity/temperature version (RHT)provides dual 4-20 mA or 0 to 10 VDC output signals to control both humidity and temperature with one sensor which reduces installation costs.The duct
mount version is also available with an optional alpha-numeric LCD to provide local indication of humidity and temperature simultaneously. The displayed temperature is field selectable for °F or °C.Monitor humidity in ducts,rooms,and outside air.
