TEMPERATURE ALARM SYSTEM, TEMPERATURE ALARM METHOD, AND PROGRAM

摘要

To provide a temperature alarm system that emits an alarm when the temperature of an electric heating body itself reaches a predetermined specific temperature.SOLUTION: The invention, in which a heating wire 20x is formed of a nickel chrome wire in which the temperature-to-resistance characteristics have a maximum and a minimum, comprises: a temperature control unit 40 that energizes the heating wire 20x of an electric resistance heater 20 to increase the temperature of an object to be heated 90 toward a predetermined target temperature; a resistance calculation unit 44 that measures, moment by moment, the value of resistance indicated by the heating wire 20x as the value of resistance during temperature increase during the increase in temperature of the object to be heated 90 performed by the temperature control unit 40; a maximum and minimum determination unit 46 that determines whether the value of resistance during temperature increase indicates a maximum or a minimum during the increase in temperature of the object to be heated 90; an alarm signal generation unit 47 that, when the value of resistance during temperature increase indicates a maximum or a minimum, generates an alarm signal corresponding to the maximum or the minimum.SELECTED DRAWING: Figure 1
