The invention concerns a fitting for a cooking vessel comprising a cooking pot and a cover, especially a steam pressure cooker, with a temperature sensor attached to the cooking vessel, the temperature sensor emitting an electrical signal corresponding to the temperature inside the cooking vessel. In order to precisely detect the temperature of water contents during the heating phase, and in order to be able to use it for indicators, control, and regulation, the temperature sensor is attached to a measuring point in a heat-conducting contact to the external side of the cooking pot in the transition area between the pot bottom and the pot wall, at which point the temperature difference between the temperature of the water contents and the external temperature at the measuring point during the heating process is approximately nil.
A cooking utensil comprising a cooking pot having a vertical wall and a base and a cover with water contents (W), with a temperature sensor attached to said cooking pot, which emits an electrical signal corresponding to the temperature inside said cooking utensil, characterized by having a temperature sensor (17) attached by means to the external surface of said cooking pot (10) at a point selected adjacent said wall at the beginning of the transition region (13) between the wall (12) and the base (11) of said pot by a heat-conducting connection to a measuring point (14), the temperature difference (.DELTA.T) between the temperature (Tw) of said water contents (W) and the temperature (Ta) of said external surface of said cooking pot (10) at said measuring point (14) is, during heating of said liquid contents until said contents reach a critical temperature of about 100.degree. C., approximately zero.
