MCG 300 Resistance Temperature Detector

Resistance Temperature Detector
The MCG 300 Resistance Temperature Device (RTD) measures spot temperature by outputting a resistance change to a gauge or transmitter. This change in resistance, which is directly proportional to temperature, is detected by a precision input bridge circuit in the transmitter.

In addition to two element leads, a third reference lead is provided. The reference lead is used to remove lead wire resistance from the measurement of the temperature elements.
