SummaryFCI provides temperature transmitters mounted in
thermowells with integral or remote solid state electronics housed
in protective hermetically or environmentally sealed enclosures for
direct installation into piping and ducting on commercial and
military aircraft, spacecraft, vehicles and marine applications.
These transmitters utilize highly reliable Resistance Temperature
Detector (RTD) elements that provide a linear change in resistance
that is directly proportional to temperature changes in the liquid
or gas process. The FCI provided electronics are designed to provide
up to three separate analog, digital or switch outputs that are
calibrated by FCI over customer specified ranges to indicate
temperature changes in the customer’s process fluid. The outputs are
typically specified as 0 – 5 Vdc, 4 – 20 milliamps or a digital buss
that interfaces with customer systems. FCI can provide Built in Test
(BIT) or other type of health monitoring options on the output. FCI
can also provide thermistor and thermocouple elements with
transmitter electronics for requirements specified by the customer.
