Estimating the term…
A vibration sensor (1) is provided for direct or indirect mounting on a vibrating component such as an engine block. The vibration sensor has a housing (10) and a pressure sleeve (2), which includes a central bore (14), a cylindrical area (12) and a flange-like edge (13). A piezoelectric disk (3) is situated between two contact disks (7). A seismic mass (4) acts on piezoelectric disk (3) by way of a spring element (5) and a threaded ring (6). Insulating disks (8) are situated on the sides of the contact disks (7) facing away from the piezoelectric disk (3). The insulating disks (8) have an inside diameter (D1) that is less than an outside diameter (D2) of the cylindrical area (12) of the pressure sleeve (2).
