Abstract
A vibration transducer has a pressure sleeve fastenable directly or indirectly on a structural component part causing vibrations, a sensor element which is held at the pressure sleeve on a radial outer side with an axial pretensioning, a plurality of contact disks including at least one contact disk provided with a radial inclination so as to form a plate spring for generating the axial pretensioning of the sensor element, and a seismic mass provided with an internal thread and screwable directly to the pressure sleeve for clamping the sensor element.
