Optical & Non-contact Data-transmission System of Rotating Spindle Temperature by Adopting One-chip Micro-controller(2nd Report)

Measurement Accuracy

Abstract

This paper deals with the measurement accuracy superior than 0.05-0.1°C for 0-50°C range of the developed data-transmission system. To realize the measurement accuracy best, it is necessary to satisfy several conditions; namely the calibration of the system should be carried out under several different temperatures or more and under sufficiently insulated condition, the output of all channels should be compensated based upon the temperature of electric circuit board and the warm-up operation for electric parts is needed.
