Wall Mount Enclosures, Transmitter

The ACI Transmitter Room Series features a two-wire, 4 to 20 mA loop powered output with
optional 3-Wire voltage output signals available. 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.

Applications: Space Temperature Sensing, Oce Buildings, Schools, Gyms, Manufacturing Plants, Pharmaceutical, Hospitals, Data Centers
