Abstract
The sensor comprises a deformation element (111) that is flat at least in sections and has a planar surface (111+) and an opposite planar surface (111 #), a sensor lug (112) extending starting from the first surface (111+) of the deformation element, a connection sleeve (113) extending starting from the deformation element, a transducer element (12), which is arranged within the connection sleeve (113) and contacts the surface (111+) of the deformation element with a contact surface, for generating an electrical sensor signal representing temporally changing movements of the sensor lug and/or temporally changing deformations of the deformation element, as well as fastening means, which are positioned within the connection sleeve (113) and are mechanically connected thereto, for fixing the transducer element (12) in the connection sleeve (113). The fastening means (13) of the sensor according to the invention comprise a spring assembly (131) formed by means of at least two stacked disk springs, wherein the disk springs are elastically deformed by exerting a pressing force which holds the transducer element against the deformation element.
