Low Temperature Transmitters

Product Description:

The ACI/TT100-LT and ACI/TT1000-LT Series temperature transmitters incorporate a Class B wire wound platinum RTD sensor which conforms to DIN-IEC-751 platinum RTD standards.

ACI produces two temperature transmitters, the ACI/TT100-LT for use with a 100 ohm RTD input and the ACI/TT1000-LT 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 to 5 or 2 to 10 VDC can also be ordered. The input voltage to the transmitter may vary from 7-35 VDC. The transmitter is supplied factory calibrated and is protected from EMI and RF interference when using a 4-20 mA output. The transmitters output current can be limited upon request.

One of the most important features of the ACI/TT100-LT and ACI/TT1000-LT temperature transmitters is the use of a strain free wire wound RTD. This allows the sensor to have a more stable output since the sensing element isn't subjected to the constant expansion and contraction of the encapsulation marterials. The sensors are mounted in a 1/4" diameter stainless steel probe and come with standard 24" teflon leads except for the remote probes which come with 10' teflon leads.

Some of the typical applications are for Freezers, Chemical Plants, Fuel Processing Facilities, Meat Packing Plants, and Scientific Laboratories.

These units are offered in Duct, Duct without box, Immersion, and Remote Probe configurations.
