Abstract: Weight or force measuring apparatus including a vibratory beam (102) as the force sensor which vibrates at a measurement frequency related to the stress applied to the beam by a weight. A reciprocatory mass (106, 108) is coupled to the beam intermediate nodal points of the beam (102) so as to reciprocate at the measurement frequency of the beam (102) and increase the Q of the beam (102).

Abstract: A force or load sensor (21) having a vibratory beam (22) whose frquency of vibration varies in accordance with stress induced by an applied load. The sensor (21) includes end portions (24) for mounting the sensor (21) so as to accept the load, the end portions (24) having regions (26) which are fully clamped adjacent the beam (22) to prevent resonance beyond the beam (22). The sensor (21) may incorporate additional beams (27) to carry a proportion of the applied load.
