Abstract
A vibration pickup has a pressure sleeve which is directly or indirectly mountable on a component causing vibration, a seismic mass, a sensor element arranged under the seismic mass and held with an axial pretensioning radially outwardly on the pressure sleeve and is electrically contactable, the seismic mass in non-mounted condition abutting only partially against an arrangement with the sensor element while in predetermined ring-shaped regions a distance is available to the arrangement with the sensor element, and after mounting with covering of the distance a substantially plane abutment of the seismic mass against the arrangement with the sensor element with an axial pretensioning is produced.
