Improving temperature measurement precision by using computer data processing

Two revisional algorithms are discussed here. These algorithms are used to improving platinum resistance temperature sensor measurement precision by using computer data processing. A multi-channel temperature data collector is linked to computer via USB bus. Pt100 platinum resistances are used as temperature sensors. Effectively improving temperature measurement precision by revising R0 (resistance at 0°C of Pt100) and W1 (ratio of Pt100’s resistance at 0 0 100°C and 0°C). We obtain higher measurement precision using inexpensive class B Pt100 temperature sensor.
