BEAM STRUCTURE FOR PIEZOELECTRIC VIBRATING BEAM FORCE OR PRESSURE SENSORS |
摘要 |
Vibrating beam force sensors have a relatively low Q unless there can be prevented energy loss to the mountings at either end of the beam. This can be achieved by providing some sort of counterbalanced vibrating element; the available beam structures, which are all quite complex, involve balancing beams or counterweights that are in the vibrational plane of the 'main' beam, and flex in that plane.
<??>The invention provides a mechanically simpler but no less efficient beam structure by placing counterbalancing beams not above and below the main beam but on either side thereof. |
