Platform scale with bendable load sensing beam

摘要

A platform type weighing scale having four platform suspensions mounting a scale platform on a base, a bendable load sensing beam supported by a pair of spaced beam suspensions on the base, first and second transfer means respectively interconnecting first and second pairs of said platform suspensions to each other and to sensing beam at first and second points spaced along the beam to preselected distance from the first and second beam suspensions respectively to apply first and second forces to the sensing beam in a direction transverse thereto that are respectively correlative with the sum of the loads applied to the first and second pairs of platform suspensions, and electrical transducer means for sensing the sum of the moments produced in the sensing beam by the first and second forces.
