ABSTRACT:
A relative vibration sensor includes a transducer container vessel including a cavity surrounded by two parallel deflective walls on two opposite sides and rigid walls on other sides, a piezo electric disc element disposed within the cavity intermediate the two parallel deflective walls, at least two electrodes respectively belonging to two opposite halves of the piezo electric disc element respectively located on two opposite sides of a reference plane intersecting with the two parallel deflective walls of the cavity in a substantially perpendicular relationship, and a pair of elongated vibration sensing members respectively extending from the two parallel deflective walls of the cavity towards an approximately common direction perpendicular to the reference plane, wherein vibrations of two mechanical members respectively transmitted to the pair of elongated vibration sensing members generate two alternating electrical signals respectively from the two opposite halves of the piezo electric disc element, which two alternating electrical signals are combined into a resultant electrical signal representing the relative vibration between the two mechanical members.
