<p>A pressure-detection method and detection device for electric pressure cooker is used for detecting continuously and accurately to control the pressure in the electric pressure cooker. The method comprises that a strainometer is provided outside a interior-cooker of the electric pressure cooker, and a transmission arm is utilized to sense the expanding amount of the interior-cooker and converts the expanding amount into a displacement, then makes the elastomer of the strainometer distorting; the distorting elastomer generates subsequently a controllable electric signal due to the electric characteristic of a sensitive foil, and the controllable electric signal is delivered to a central control unit, then control signals and display signals are outputted by the central control unit. The detection device comprises a strainometer, a transmission arm, a central control unit and the like. The strainometer is provided outside the interior-cooker of the electric pressure cooker and is fixed by a proper way.</p> |
