ABLE ARH-T-3-I-W Wall Mount Humidity / Temperature Transmitter, 3% Acc

The ARH-T-3-I-W humidity / temperature transmitter comes with a single channel 4 to 20 mA two wire output for RH and a 10K thermistor for temperature It is designed for wall mount HVAC / BMS applications. The enclosure is vented on both sides to allow free circulation of air around the sensing element for a truly representative measurement. Furthermore, the humidity sensor is a bulk polymer resistive element which, due to the stability of the polymer, has an inherent tolerance to contaminants and/or extreme environmental conditions. This results in very low calibration drift. The sensor’s resistance value changes logarithmically in response to fluctuations in relative humidity facilitating optimum resolution. Temperature measurement is via a highly reliable 10K thermistor. Prior to delivery, all transmitters are individually calibrated to internationally traceable standards by a qualified ABLE technician using a divided flow humidity generator referenced to a chilled mirror hygrometer. An installation / wiring guide is provided within the packaging.
