Abstract
A part to be mounted into force or pressure sensors includes an annular measuring element made of piezoelectric material. First and second electrodes rest against respective opposite sides of the measuring element and are provided with wires. An electrically insulating transmission member laterally adjoins the first electrode, across from the measuring element. Another electrically insulating insulation member laterally adjoins the second electrode, across from the measuring element. All components are mounted within the part in such a way as to be centered relative to each other. The external face of the transmission member and the external face of the insulation member which face away from and run parallel to the electrodes are designed in a very planar manner, having a levelness of less than 10 μm.
