Design of Signal Conditioning Module of PT100 Temperature Sensor Detection System
Abstract:
The measuring circuit of signal conditioning module of platinum resistance temperature sensor detection system uses a sub-three-wire connection mode. It can improve the measurement accuracy and reduce the measurement error caused by the external circuit. The amplifier circuit is an operation circuit using in phase input. The system can achieve multi-channel measurement of sensor by using multiplexer with the measurement accuracy of 0.1oC.
