Matched Temperature Transmitters
ACI/TTM100
ACI/TTM1000



Product Description:

The ACI/TTM100 and ACI/TTM1000 Series transmitters provide a highly accurate current output. To obtain the high accuracy, the transmitter is calibrated while the sensor is in an environmental chamber. The standard deviation is then documented on a Certificate of Calibration at 3 points as compared to an NIST Traceable thermometer. Each unit includes a two-wire RTD that conforms to IEC 751 platinum RTD standards.

A matched transmitter works with either a 100 or 1000 Ohm RTD. The transmitters produce a linear 4-20 mA output carried on a two-wire system. Optional voltage ranges (1-5 or 2-10 VDC) can also be ordered. The 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, from any range between -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 power input.

The 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 also be ordered on a surface plate made of either stainless steel or aluminum. For measuring pipe temperature TT's can be ordered with a strap. For air duct measurement's TT's are offered with 4, 8, 12, and 18" probes or as a remote probe with 6 foot leads. There are also averaging configurations in 12 and 24' lengths made of soft copper tubing to fit in any duct work. Lastly, the TT's can come as immersion with 4 or 8" high quality stainless steel thermowells. All the duct and outside air configurations are available inside a weatherproof enclosure.
