LP-TR Pt100 Temperature Transducer

LP-TR Pt100 Temperature Transducer

The LP-TR converts the resistance value of a Pt100 Platinum resistance element into an analog voltage or current output proportional to the temperature.
The three wire method of connection is used and the Pt100 signal is fully linearised.
