The sensing elements multilayer construction also provides excellent resistance in applications where dust, dirt, oils and common environmental chemicals are found. The RH duct sensors include on board DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Each unit also contains 0%, 50%, and 100% test options to verify that the transmitter is both working and wired properly. Field calibration can be performed by using the increment and decrement calibration DIP switches without the need to replace the sensing element. These enhancements provide increased exibility and outstanding long-term reliability without the need to replace the sensors in the eld. Duct con gurations feature a weatherproof Euro style enclosure with a gasketed cover and conformally coated circuit boards for increased moisture resistance in high humidity environments. The sensor is protected by a stainless-steel sintered lter. Three and Five-point NIST Calibration Certi cates are available and must be ordered separately when placing your order.Applications: Humidi cation, Dehumidi cation, Supply / Discharge / Return Air, Economizers, Clean Rooms, Data Centers, Process Control, Schools, Hospitals, O ce BuildingsThe ACI RH Duct is covered by ACI's Five (5) Year Limited Warranty.
