摘要：

According to a number of issues in the traditional temperature measurement, the multi-channel temperature measurement system based on virtual instrument is developed. In terms of measurement range and accuracy, Integrated Temperature Sensor TMP36, platinum resistance Pt100, and K-type thermocouple are selected to achieve multi-point temperature measurement, signal conditioning circuit is designed to match with every sensor. On this basis, combined with the technical parameters of each component, by means of the theory of uncertainty, analysis of the total uncertainty of system has been made. The calculation results show that the selection of each component for the temperature measurement system is reasonable, which can completely meet the measurement requirements.
