ABSTRACT:
An electronic scale used for weighing an object or material. The scale includes a weighing platform arranged to move upon receipt of a material thereon. The device further includes support means, a variable capacitor having a first and a second plate, spring means which is coupled both to the frame means and to the platform means such that movement of the platform means upon receipt of the material thereon causes the spring means to twist about an axis. The scale further includes counterbalancing means and energy absorbing connecting means to prevent error from being introduced into the weighing process, should vibrational moments be transmitted to the scale from its external environment. An alternative embodiment of the invention entails a flexure base scale, adapted to be used with counterbalancing means.
