Paper Title:
Temperature Measurement with High Accuracy
  Abstract

Calibration of general temperature sensor, platinum resistor is done with measuring its zero resistance and dispersity of linear system and compensating. Accurate constant current source is used to provide platinum resistor sensor power and four-wire measuring method is designed for self-compensation of lead wire resistance. With amplifying the changing signal of platinum using amplifier of high precision and low temperature drift, and MCPU digital filtering, highly accurate temperature measurement result is got finally.
