DUCT

Duct Sensors with Transmitters

The ACI Transmitter Duct Series features a two-wire, 4 to 20 mA loop powered output signal
with an optional 3-Wire voltage output signal 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 help eliminate the possibility of noise being introduced onto the signal lines.
The sensor assemblies are manufactured using colored Etched Teon lead wires and ACI’s
proven double encapsulation process to eliminate the eects of moisture on the sensors as well
as increased response times using our high quality, thermally conductive epoxy. The duct

sensors include a foam pad to properly seal the duct and limit vibration once installed.
Optional NEMA/IP rated weather proof enclosures are available as specied on the back of the product data sheet. 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: Chilled Water Systems, Hot Water Systems, Boilers, Pumps, Compressors, Chillers, Cooling Towers, Process Control
