Low Temperature Outside Air Sensor & Transmitters
The ACI Low Temperature Outside Air Series temperature sensors and transmitters are a single
point sensor featuring a three wire RTD sensor assembly with 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 3rd wire (White) wire connected to the
second RTD Terminal block. The purpose of the 3rd wire is to compensate for external lead wire
resistance that will aect the accuracy of your sensor output when using with a three wire
temperature transmitter or sensor conguration 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 the A/100/1K-3W-O style Platinum RTD series sensors
without temperature transmitter. The operating specications are for both the sensor and
transmitter as designated in the specication table. The transmitter is mounted in the
mounted in the Aluminum Bell Box for mounting outdoors due to the extreme temperatures. NIST Certicates are available for all of the
congurations 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 with a 3 or 5 Point NIST Calibration Certicate since they include a second calibration step in which the RTD and
transmitter are calibrated together as a system, which will remove most of the sensor error over the calibrated temperature span of the transmitter.
Applications: Freezers, Outside Air Temperature, Cold Storage Facilities, Manufacturing Facilities, Process Control
Galvanized junction and should be mounted inside your building with the sensor assembly
