Abstract
Disclosed is a system for accurately sensing the temperature of articles being heated in a microwave oven. Basic structural elements of the invention are a housing that defines an oven chamber, a door providing access thereto and an energy source for transmitting microwave energy into the chamber. A temperature responsive sensor is positioned within the chamber and is adapted to sense the temperature of articles being heated therein. Enclosing the sensor is an elongated sensor body formed of an electrically conductive material so as to provide a shield for microwave energy and having a length that establishes therfor a detuned antenna condition at the microwave transmission frequency of the source. An electrical control circuit is coupled between the source and the sensor and controls energization of the source in response to temperature levels sensed by the sensor.
