Humidity / Temperature Combination Units

The A/RH Series Relative Humidity Transmitters, convert a resistance change to a linear 4 to 20 mA, 0 to 5 VDC, 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 thermistors, rtds, 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% units, the +/- 1% accuracy specification is good for a 20% range that you provide at the time of your order. Example Part #: A/RH2-TT100(20 to 120F)-R
