Accelerometer |
| abstract |
The invention is directed to a three-axes translational, digital accelerometer, comprising a proof mass contained within a cavity which closely surrounds the proof mass with a dampening liquid filling the space between the proof mass and the inner walls of the cavity. The proof mass is constructed and arranged to have a cubical coefficient of expansion substantially the same as that of the dampening liquid so as to minimize any temperaturedependent scale factor changes. Means are provided for detecting departure of the proof mass from a mull position within the cavity under the influence of an acceleration force. Additional means are provided which are responsive to the detected departure of the proof mass from a null position which means are used to force the proof mass towards the null position such that the amount of force required is directly proportional to the acceleration sensed by the proof mass. |
