All transmitters include Zero and Span adjustments for eld calibration and are calibrated using NIST Certi ed Calibration equipment. ACI recommends the use of an 18 to 22 AWG shielded cable for all temperature transmitter installations to reduce the chances of noise being introduced onto the signal lines. The room transmitters are designed to be mounted over a standard single gang junction box or hole in the wall and includes a foam pad to reduce the e ects of self-heating from the transmitter and thermal drafts from within the wall. For best accuracy, ACI recommends the use of the A/TTM Series Matched transmitters with 3 or 5 Point NIST Calibration Certi cate, since they include a second calibration step in which the RTD and transmitter are calibrated together as a system. Optional Set Point, Override and Loop Powered LCD Display. Applications: Space Temperature Sensing, O ce Buildings, Schools, Gyms, Manufacturing Plants, Pharmaceutical, Hospitals, Data Centers The ACI Transmitter Room transmitters are covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, www.workaci.com.
