Stainless Steel Immersion, Transmitters
The ACI Transmitter Immersion Series features a two-wire, 4 to 20 mA loop powered output
signal with optional three-wire voltage output signal available. All transmitters include Zero
and Span adjustments for eld calibration and are calibrated using NIST Certied Calibration
equipment. We recommend the use of an 18 to 22 AWG shielded cable for all temperature
transmitter installations to keep noise from being introduced onto the signal lines. The sensor
assemblies are manufactured using Etched Teon colored lead wires and ACI’s proven double
encapsulation process to eliminate the eects of moisture on the sensors as well as increased
response times from our high quality, thermally conductive epoxy. The immersion sensors “-I”
include a welded thermowell but can be ordered without the thermowell “-INW” version. The
existing thermowell application. Optional NEMA/IP rated weather proof enclosures and NIST Calibration Certicates are available when ordering
the A/TTM Series transmitters as referenced in the ordering grid on the back of the product data sheet. For best accuracy, ACI recommends the use
of the A/TTM Series Matched transmitters which includes 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.
Applications: Chilled Water Systems, Hot Water Systems, Boilers, Pumps, Compressors, Chillers, Cooling Towers, Process Control
“-INW” includes a standard ½” NPS process thread to be used with a machined thermowell or
