OVERVIEW | ACI: Transmitter, 10K, High Temperature Duct, 12", 4-20mA Output
ACI High Temperature Duct Series sensors and transmitters are a single point duct sensor featuring a three wire RTD sensor assembly and a 316 Series stainless steel probe. The three wire sensors can be used with a two wire transmitter by connecting the two (White) colored wires to one of the RTD terminal blocks with the third wire (Red) 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 a Building Management System or PLC (ProgrammableLogic Controller. ACI recommends the use of 18 AWG lead wires to reduce the external lead wire resistance when using the A/100/1K-3W-D style Platinum RTD series sensors without temperature transmitter.
Standard enclosure options include the “-GD” Galvanized or “-BB” Aluminum weather proof enclosure. For best accuracy, ACI recommends the use of the TTM100 or TTM1K Series Matched transmitters with a 3 NIST Calibration Certificate 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: Burners, Boilers, Stacks, Exhaust, Incinerators, Ovens, Conveyor Systems, Process Heating, Process Control
