ACI A/TT100 Series A/TT1K Series A/TTM100 Series A/TTM1K Series Temperature Transmitters

Temperature Transmitters
A/TT100 Series A/TT1K Series A/TTM100 Series A/TTM1K Series

ACI temperature transmitters are a cost effective solution for all of your temperature measurement needs. The transmitters are accurate, durable, and reliable. Numerous mounting configurations are offered. ACI produces two temperature transmitters, the A/TT100 for use with a 100 Ohm Platinum RTD and the A/TT1K for use with a 1K Ohm Platinum RTD. The transmitters produce a linear 4-20 mA output carried on a two-wire system. Optional output voltage ranges of (+1-5 or +2-10 VDC) can also be ordered. The transmitter is supplied factory calibrated, and supplied with zero and span potentiometers for field calibration. The transmitter is linear from -50 to 392°F. The A/TTM Series transmitters are calibrated using a high accuracyNIST traceble digital thermometer and temperature chamber at three points standard.
