A/RH3-CP-D - The A/RH Series (resistive temperature output) relative humidity transmitters utilize a capacitive sensing element to deliver a proportional analog output.  The 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. Single point field calibration Field selectable output signals (0-5 VD 0-10 VD 4-20 mA)

A/RH3-CP-O-4X - The A/RH Series Relative Humidity 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. This unit is combined with a temperature sensor to provide added installation flexibility. Temperature outputs include a wide variety of thermistor rtd semiconductors and temperature transmitters. Please see the cut sheet listed above the comprehensive listing of temperature outputs that are available. Each A/RH Series humidity transmitter is calibrated using a NIST Traceable Temperature and Humidity Chamber. For A/RH1% unit the +/- 1% accuracy specification is good for a 20% range that you provide at the time of your order.
