Abstract
A vibrating beam resonator is formed with a unitary isolator mass at each end of the vibratory beam. Isolator springs connected to the unitary masses are joined to mounts. Forces applied to the mounts cause the vibrating beam frequency to vary to enable precise force measurements. With this arrangement, fewer cutting operations are required to produce the vibrating beam resonator than were necessary with known resonators. In a preferred embodiment, a side of the vibratory beam is formed by an edge of the crystal blank from which the resonator is cut to further reduce cutting time. This also permits cuts to be made from only one side of the blank.
