Patent ID: 7673515

Claim:
A vibration sensor having two or more paired transducers, the sensor comprising: a chamber within a housing, the chamber including: a center; a surface in which all portions of the surface are substantially equidistant from the chamber center; a volume of a vibration-sensitive fluid substantially in contact with the surface; two or more paired vibration-sensitive transducers, wherein each transducer of each of the two or more pairs is adapted to communicate with at least one signal interpreter, each transducer further having a body including: a first end portion, a second end portion and a central axis segment passing axially through the center of the body, between the first end portion and the second end portion; the first end portion being operatively associated with the chamber surface and including a transducing element receptor portion, at least a portion of the transducing element portion being substantially in contact with the fluid; the second end portion being in operative association with the chamber housing; each transducer pair of the two or more paired transducers includes; an axis passing through the central segment of a first transducer; the chamber center; and the central segment of a second transducer.
