<p>Forces caused by the applied load are transformed into moments of opposite sense and applied to opposite ends of a beam. Deflection of the beam is measured by centrally disposed strain gauge resistors to produce an electrical signal proportional to the load. The conversion of load to moments of opposite sense is accomplished by a pair of spaced parallel pivot members which are suspended by straps between the load-receiving pan and the base such that the pivots tend to rotate in opposite directions. The beam is mechanically connected between the pivots such that it is subjected to the bending moment over substantially its entire length.</p> |
