Abstract

A weighing cell which is protected against overloading due to mechanical shock and delayed weight readout due to vibration. The weighing cell, which has a platform, a self-contained base and a load cell operatively connected therebetween, includes, in one embodiment, a plurality of posts connected to the base and separated from the platform by a gap to protect against overload forces applied to the non-axial region of the platform. Feet on the base of the weighing cell have an energy absorbing material thereon and are placed outboard of the load cell to provide quick damping of vibrations caused when a load is placed on the platform. The load cell is spaced at a partial gap from the base and platform to protect it from overload forces applied to the axial region of the platform.
