ABSTRACT:
A flexure plate dual capacitance accelerometer system includes a flexure plate fixed having edges fixed to a housing structure. A first fixed plate is coupled to the housing structure a distance from one side of the flexure plate. A second fixed plate is coupled to the housing structure a distance from the other side of the flexure plate and disposed substantially parallel with the first fixed plate. The two fixed plates and the flexure plate form dual capacitors, one on each side of the flexure plate. The flexure plate flexes in response to acceleration, thereby altering the two distances and generating phase shift capacitance signals from the dual capacitors.
