Abstract
A temperature sensor is disclosed comprising a sensor element having a temperature-dependent resistance that is enclosed with a tube. In one embodiment, the tube is a quartz glass tube. In another embodiment the temperature sensor is a conventional halogen lamp, designed for use as a light source. The temperature sensor can be advantageously to precisely measure temperatures in a radiant heater, such as that present in a electric cooking appliance.
