ABSTRACT:
An accelerometer having a pair of piezoplates and masses compressed to a center post by a bolt through bores in the center post, piezoplates and masses without mechanical or electrical contacting the piezoplates or the center post. A symmetrical arrangement includes opposed pairs of piezoplates separated by the center post or two pairs of piezoplates separated from each other by center post. Two bolts through orthogonal bores in a single center post or two perpendicular center post provide two and three axis of force sensing. Either linear or angular acceleration can be sensed. Two orthogonal mounting bores in the housing allows adjustment of the sensing axis.
