摘要:
A platform scale in which the force applied to the platform is transmitted to a capacitance transducer whereby the output of the transducer is correlated to the force on the platform. The transducer includes two parallel square plates spaced apart and insulated from each other. Each plate has four slots, one projecting inwardly from each edge of each plate and each slot being generally parallel to the adjacent edge whereby each plate has four identical cantiliver beams. The free ends of each beam of one plate are connected to but insulated from the free ends of the corresponding beams of the other plate. The space between the plates constitutes the dielectric of the transducer and this space is reduced by an amount virtually correlated to the force applied to the platform so that the output of the transducer is very closely correlated to the force applied to the platform on the scale.
