Abstract

This study proposed a real-time and multi-point temperature measuring system. This system is capable of measuring temperatures simultaneously from many sensors set in or on an object. Namely, the basic principle of this system is as follows : first, the data measured from the thermocouples are amplified as analog-signals and taken into the sample & hold circuit simultaneously at intervals of a setting time step. Next, while a set of this data has been held in the sample & hold circuits, it is switched in turn over to an A-D converter by an analog multiplexer, then each set of data is transformed to digital by the A-D converter. After that, they are displayed with a personal computer simultaneously. This instrument can grasp in detail a heat transfer phenomenon which is changing unsteadily with time.<BR>As a practical application, for the purpose of comparing this system with a scanning system, which has been generally used before, a thermal mixing process was measured with both systems, and this system was found to be more useful than the scanning system. For further practical use, the following measurement was also carried out : the measurement of changing temperature distribution in solution polymerization.
