ABSTRACT:
A measuring apparatus in which two opposite sides of a load receiving plate to which a load is to be applied are coupled to two sides of an inner frame enclosing the load receiving plate by means of at least four inner beams. The measuring apparatus also comprises an outer frame enclosing the inner frame, two sides of which are coupled to other two sides of the inner frame by means of at least four outer beams, whereby the load receiving plate and inner frame are supported by the outer frame. Further, strain gauges are provided on the inner and outer beams, and strains of these beams are detected by the strain gauges and measured as electrically processed and amplified.
