Document Type and Number:
Japanese Patent JP3288699
Kind Code:
B2
Abstract:
An accelerometer that includes a proof mass assembly comprising a paddle flexurally mounted to a support, a sensing circuit for detecting movement of the paddle, and a force rebalance system. The sensing circuit includes a capacitor plate positioned on a surface of the paddle. The proof mass assembly is clamped between upper and lower mounting pieces positioned on opposite sides of the proof mass assembly from one another. One or more fasteners extend between the upper and lower mounting pieces through the proof mass assembly. The support is shaped so as to form openings through which the fasteners pass, such that the support isolates each fastener from the paddle. This arrangement isolates the paddle from a source of contamination, provides for a more evenly distributed clamping force, and minimizes distortion of the mounting pieces. The fastener openings in the support may be shaped so as to limit movement of the paddle towards the flexures.
