Abstract (en)
[origin: WO2009067833A2] The invention relates to a part (2) to be mounted into force or pressure sensors. Said part (2) comprises an annular measuring element (2) made of piezoelectric material, first and second electrodes (4, 4') that rest against both sides of the measuring element (3) and are provided with wires (10, 10'), an electrically insulating transmission member (5) that laterally adjoins the first electrode (4), across from the measuring element (3), and an electrically insulating insulation member (6) which laterally adjoins the second electrode (4'), across from the measuring element (3). All said components (3, 4, 4', 5, 6) are mounted within the part (2) in such a way as to be centered relative to each other. According to the invention, the external face of the transmission member (5a) and the external face of the insulation member (6b) which face away from and run parallel to the electrodes (4, 4') are designed in a very planar manner, having a levelness of less than 10µm.
