Reducing Compensation Approach for Temperature Drift in Temperature Measurement
Cao Yu · Jiliang xuebao · 2003
The causes of temperature drift in temperature measurement is analysed, and a reducing compensation approach to eliminate the temperature drift is described. In the algorithm, in order to eliminate the temperature drift, through two standard resistors used as intermediate transferrers, the samples in the measuring state are reduced to the samples in the normal state. The experiment results show that the measurement accuracy is less than reach 0 2% after compensating.
