PROBLEM TO BE SOLVED: To make it possible to monitor an increase in temperature for a part accurately, regardless of environmental temperatures, by using a first thermosensitive element for detecting an absolute temperature of the part and a second thermosensitive element for detecting the environmental temperature, and detecting an increase in temperature of the part according to the output of the thermosensitive elements. SOLUTION: A temperature detector includes a first thermosensitive element (TH1) for detecting an absolute temperature (T) of a part, a second thermosensitive element (TH2) for detecting an environmental temperature (T0) of the part, and a monitoring means 4 for detecting an increase (ΔT) in temperature according to the output (RT1 and RT2) of the first and second thermosensitive elements (TH1 and TH2) and generating an alarm signal (S) when the increase (ΔT) is above a given level. |
