中文摘要	A kind of real-time auto-calibration method of Pt Resistance temperature measurement based on multi-sensor information presented. The limitations of traditional Pt resistance temperature measurement based on bridge are overcome by dealing with the information from multi-sensor benchmark resources. (1) The intrinsic non-linear of bridge measurement is eliminated and the measurement range is broadened. (2) The temperature drift of voltage or current that provides bridge benchmark resource is resolved. (3) The additional error caused by wire resistance is eliminated. (4) The zero and sensitivity drift problems of signal measuring circuit and A/D converting circuit are resolved. Consequently high precision and long stability of Pt resistance measurement can be realized.
