Description
The standard duct without box configuration has a mounting flange for quick installation and etched-teflon leads. The sensing element is double encapsulated to avoid sensor failures caused by moisture infiltration. Additional options include: plenum rated cable and quick connects for direct termination to male VAV-Controller inputs.

3 Wire-1K Ohm
Features
The ACI Low Temperature Duct Series sensors and transmitters are a single point duct sensor featuring a three wire RTD sensor assembly using Teflon Lead wires and a 316 Series stainless steel probe
The three wire sensors can be used with a two wire transmitter by connecting the two (Red) colored wires to one of the RTD Terminal blocks with the third wire (White) wire going to the second RTD Terminal block
The purpose of the third wire is to compensate for external lead wire resistance that will affect the accuracy of your sensor output when using with a three wire temperature transmitter or sensor configuration on your Building Management System or PLC (Programmable Logic Controller
ACI recommends the use of 18 AWG lead wires to reduce the external lead wire resistance when using a Platinum RTD
The operating specifications are for both the sensor and transmitter as designated in the specification table
Standard enclosure options include the “-GD” Galvanized or “-BB” Aluminum weather proof enclosure
NIST Certificates are available for all of the configurations listed in the ordering grid on the back of the product data sheet
For best accuracy, ACI recommends the use of the TTM100 or TTM1K Series Matched transmitters since they include a second calibration step in which the RTD and transmitter are calibrated together as a system, in order to remove most of the sensor error over the calibrated temperature span of the transmitter.
