Abstract

The invention relates to a method and a device for modifying the oscillating elements of a vibration detector (1), said oscillating elements (2, 3) being fastened to a membrane (5) in the form of a vibrating fork (4). The inventive device comprises a fixing part (7) and a guiding part (6) between which the final area of an oscillating element (2, 3), which faces the membrane (5), is fixed. Also provided is a movable plunger (8) which is guided within a holding device (9) and is disposed relative to the fixed oscillating element (2; 3) such that said plunger (8) exercises a bending force upon the final area of the oscillating element (2, 3), which lies opposite the membrane (5), when being advanced.
