ABSTRACT:
A force sensor comprising a resonator (10) having a frequency that varies with the force being measured. The resonator includes an oscillatory bar (101, 102) and a pair of anchor members (12, 103, 104) that are connected each to a corresponding end portion of the bar and which are adapted to apply the force having to be measured to the bar. The sensor further comprises a tube (16) that surrounds the resonator and which is rigidly secured by its end portions to the anchor members (12).
