ACI 2% Wall, Duct and OSA Humidity Transmitters A/RH2 Series

ACI 2% Wall, Duct and OSA Humidity Transmitters

 

The ACI A/RH2 Series Relative Humidity Transmitters utilize a capacitive humidity sensor element to deliver a proportional 4 to 20 mA, 0 to 5 volt DC, or 0 to 10 volt DC output. Each relative humidity transmitter can monitor room and duct humidity as well as outside moisture. The transmitters are compatible with stainless steel wall plate applications and are designed for use in Building Automation Systems, BAS, and HVAC applications. The A/RH2 Series has on board DIP switches. These allow the user to select the desired output signal and can be powered by AC or DC power sources. Each A/RH2 Series humidity transmitter is calibrated using a NIST Traceable Temperature/Humidity Chamber. Three and five point NIST calibration certificates are available.
