Abstract

PURPOSE: To prevent the formation of local overheat portions, by observing the temp of an object, which temp must be controlled, and the temp of a heater, and by breaking a heat source of the heater when the temp of the heater becomes not more than a fixed value lower than the temp of the object to be controlled.
CONSTITUTION: The temp of an object 4, which temp must be controlled, is controlled in such a manner that a heater 1 is heated by making and breaking the output of a heater power source 2 by means of a heater power source switch 3. The temp of the object 4 to be controlled is detected by means of a detector 6 and introduced to a comparator 9, and compared with a signal from a target temp set instrument 7 at the comparator, and the result is introduced to a heater power source controlled 12. The temp of the heater 1 is measured by means of a detector 5 and introduced to a subtracter 11, the signal from the detector 6 is subtracted, at the subtracter, and the result is introduced to a comparator 10. The heater power source controller 12 judges by signals from the comparators 9 and 10, and transmits the command of make or break to the heater power source switch 3.
