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). |
