T-TRL Pt100 Temperature Transducer
Model T-TRL

T-TRL Pt100 Loop Powered Temperature Transducer

The T-TRL Pt100 loop powered temperature transducer converts the resistance value of a platinum resistance element into a load independent dc current signal.
The circuitry employed corrects the non-linear response of the Pt100 to yield a signal proportional to temperature.
