发明名称 Vibrating beam pressure sensor
摘要 A sensor providing an output indicating pressure including means to excite a vibrating beam at its natural frequency, and means to load the beam in response to pressure to alter the natural frequency of the beam. The frequency output is sensed by a capacitor pick off mounted on the same side of the beam as the means to excite the beam. Changes in the output frequency provides an indication of the pressure being measured.
