Abstract:
A vibration pickup, comprising a pressure sleeve which is placeable on a component causing vibrations; a sensor element which detects the vibration: a seismic mass which is placeable outside of said sleeve on a support surface of said sensor element with an axial pretensioning, so that said sensor element is held between said seismic mass and a flange-shaped projection of said pressure sleeve, said seismic mass and said pressure sleeve being formed as a one-piece integral component, wherein in said integral component said seismic mass with said pressure sleeve through a web which is flexible within predetermined limits, so that between said seismic mass and said flange-shaped projection a ring gap is formed, which prior to mounting of said sensor element has a smaller axial opening than an axial width of said sensor element, said sensor element being axially slotted on one side, so that during mounting of the vibration-pickup said sensor element is placed around a periphery of said pressure sleeve in said ring gap.
