Differential accelerometer, has filtering systems permitting corresponding detection systems of force sensors to move along direction perpendicular to seismic mass`s differential movement measurement detection direction

摘要

The accelerometer has force sensors with detection systems (3a-3d) for differential movement measurement of a seismic mass (1) along OX and OY directions. Filtering systems (4a-4d) are associated to the respective detection systems. Each filtering system permits the corresponding detection system to move along a direction perpendicular to the measurement detection direction without allowing movement along the detection direction.
