摘要：
A temperature sensor (30) for detecting temperature of a heating element (20) of an igniter such as a glow plug includes optic means (32) disposable near the igniter for receiving at least a portion of electromagnetic energy emitted by the heating element (20). The received electromagnetic energy is coupled to circuit means (36) for producing an output related to the temperature of the igniter in relation to a characteristic of the received electromagnetic energy. In one embodiment, the optic means (32) comprises optic fibers that receive electromagnetic energy emitted by the heating element and couple that energy to a photosensitive detector.
