Component for piezoelectric force or pressure sensors, held together by an electrically insulating film
Abstract:
The invention relates to a component for installation in force or pressure sensors, in particular in a glow plug. The component comprises a disc-type or punched-disc type measuring element consisting of a piezoelectric material, punched-disc type or disc-type electrodes that lie on either side of the measuring element. The electrodes have contact points for contacting conductors. The component comprises in addition a respective transmission body or several transmission bodies that are located outside the electrodes, on either side of the latter. The measuring element, electrodes and transmission bodies are held together mechanically by an external, electrically insulating film.
