A/RH5-R - The A/RH Series Relative Humidity Room Transmitters utilize a capacitive sensing element to deliver a proportional analog output. This series features on board DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Field calibration can be performed by using the on board increment and decrement DIP switches. These enhancements provide increased flexibility and outstanding long-term performance. The A/RH Series is covered by ACI's Five (5) Year Limited Warranty. ACI roo or wall moun relative humidity sensors are designed for HVAC or Building Automation Systems.  Typical applications include: humidity control offic pharmaceutica school office auditorium museum and hospitals. Single point field calibration Field selectable output signals (0-5 VD 0-10 VD 4-20 mA)

A/RH5-R2 - The A/RH Series Relative Humidity Room Transmitter convert a resistance change to a linear 4 to 20 m 0 to 5 VD or 0 to 10 VDC output. The Advanced Ceramic Technology design overcomes the limitations of other resistance-based humidity sensors that utilize water-soluble polymer coatings. The Advanced Ceramic Technology enables these sensors to recover fully from condensation. This also allows the sensor to maintain its accuracy over a longer period of time. Each A/RH Series humidity transmitter is calibrated using a NIST Traceable Temperature and Humidity Chamber. The A/RH Series is covered by ACI's Five (5) Year Limited Warranty.
