The invention relates to the technical field of household appliances in a kitchen, in particular to an electric pressure cooking saucepan adopting an angular displacement sensor. The electric pressure cooking saucepan comprises an inner pot, an outer pot, a pot cover and a shell; the bottom of the inner pot is provided with a heating disk of which the bottom is fixed with a post rod transmitting the pressure displacement of the inner pot; the post rod is connected with the angular displacement sensor arranged on the bottom of the outer pot or the shell through a transmission device; the transmission device having the functions of transforming the up and down displacement of the post rod into a rotation angle and transmitting the rotation angle to the angular displacement sensor is arranged on the bottom of the outer pot or the shell; the angular displacement sensor outputs different electrical signals to a control circuit according to received angular displacement signals; and the control circuit controls the heating disk connected with the angular displacement sensor to adjust the pressure in the inner pot according to different electrical signals sent by the angular displacementsensor. Therefore, the electric pressure cooking saucepan has the characteristics of novel structure and more precise measurement and control of the pressure of the inner pot.
