ABSTRACT:
A flexural vibration sensor including a housing fabricated from a magnetizable material for providing an internal magnetic path and having a coupling surface for contact with an associated structural member; electrically conductive coil means positioned within the housing; and means for generating a magnetic field within the internal magnetic path, through the coil means and along the coupling surface in the region exterior to the housing so that variations in the strength of that portion of the magnetic field in the region exterior to the housing caused by flexural vibration of the associated structural member when the sensor is attached thereto are sensed by the electrically conductive coil means and manifested by a variable electrical signal.
