Abstract:
A vibration sensor, comprising:a pressure sleeve mountable under a mounting pressure on a component causing vibration; a sensory system; and a seismic mass located above the sensory system, the sensory system and the seismic mass being held together by a screw connection on an outside of the pressure sleeve on a contact face of a flange-like segment of the pressure sleeve under an axial prestress, wherein: the seismic mass has an internal thread, the seismic mass able to be screwed on in a direction of the sensory system to produce the axial prestress in the direction of the sensory system, and one of a plurality of axial boundary surfaces of the seismic mass is concave so that an axial wall thickness of the seismic mass becomes smaller towards a center of the seismic mass, wherein at least one of the seismic mass and the sensory system includes a plurality of grooves on at least one side, a plastic being introduceable through the plurality of grooves during an injection molding into an interior space between the sensory system and the pressure sleeve.
