ABSTRACT:
The accelerometer includes an inertial mass, a fixed base and at least one or more supports/sensors for supporting the mass from the base rendering the support system statically indeterminate. The supports/sensors are preferably double-ended dual beam tuning forks suspended between mounting pads and vibrated by an oscillator. By adding one or more supports/sensors beyond those supports/sensors necessary for a statically determinate support system, the support system is rendered statically indeterminate and therefore sensitive in one or more directions.
