ABSTRACT:
An electromagnetic oven is provided with a control system comprising a ferrite sensor located within the oven, a magnetic property detector coupled to the sensor, and control means responsive to signals from the detector. The sensor is positioned on a tray together with the items to be heated and this assembly is preferably cooled to a uniform low temperature before the tray is placed in the oven. The sensor is thus subjected to the same thermal environment as the items on the tray so that when the tray is placed in the oven the time required for the sensor to reach its Curie point and shut off the oven is dependent upon the thermal "history" of the items on the tray.
