Temperature Transmitters

Product Description:

ACI temperature transmitters are a cost effective solution for all temperature measurement. The transmitters are accurate, durable, and reliable. Numerous configurations for measurement in many different mediums are offered.

ACI produces two temperature transmitters, the ACI/TT100 for use with a 100 ohm RTD input and the ACI/TT1000 for use with a 1000 ohm RTD input. The transmitters produce a linear 4-20 mA output carried on a two-wire system. Optional voltage ranges of (1-5 or 2-10 VDC) can also be ordered. The power input to the transmitter can vary from 7 to 35 VDC, can be unregulated, and is not polarity sensitive. The transmitter is supplied factory calibrated, but also has zero and span potentiometers for field adjustments or calibration. The transmitter is linear from -50 to 392oF. The current output is unsusceptible to EMI and measurement resistances less than 800 Ohms. Additional options include current limiting and an AC input.

The ACI transmitter is available in numerous configurations to satisfy all the industry standards. The room transmitter is encased in an unobtrusive plastic enclosure and can be equipped with setpoint and override combinations. The transmitter can be ordered on a surface plate made of either stainless steel or aluminum. For air duct measurements, TT's are offered with 4, 8, 12, and 18" probes, as a remote probe with a 6 foot lead wire, or as strap-on. There are averaging configurations in 12' and 24' lengths. Lastly, the TT's can come as immersion with 4 or 8" high quality stainless steel thermowells. All duct and outside air configurations are available inside a weatherproof enclosure.
