Pt100 LOOP POWERED TEMPERATURE TRANSDUCER
The C&C T-TRL Pt100 loop powered temperature transducer converts the resistance value of a platinum resistance element into a load independent dc current signal capable of driving a number of independent instruments. Low voltage dc power for the unit is fed from the remote measuring instrument via the two wire signal line. The three wire method of measurement employed ensures that reasonable cable resistance values can be accommodated without affecting the accuracy of the reading. The circuitry employed corrects the non-linear response of the Pt100 to yield a signal proportional to temperature.
