Abstract
Disclosed is a low profile load sensor comprising, an outer frame for mounting on a base of a weighing scale; platform mounting members for connecting to a platform of the weighing scale, a sensing device, and a plurality of load transmission beams positioned between the outer frame and the platform mounting members for receiving a load applied to the platform on a plurality of load-applied-points through the platform mounting members in distributed condition. The load is supported on a plurality of fulcrums in distributed condition and collectively transmitted to the sensing device which then produces a strain or a deformation responsive to the load. The load transmission beams are coupled to the outer frame and the platform mounting members via torsional elastic couplings, respectively.
Claims7
A low profile load sensor for use with a weighing scale having a base and a platform, said load sensor comprising:
- an outer frame for mounting on said base;
- platform mounting members for connecting to said platform;
- a sensing device;
- a plurality of load transmission beams positioned between said outer frame and said platform mounting members for receiving a load applied to said platform on a plurality of load-applied-points through said platform mounting members in distributed condition, for supporting said load on a plurality of fulcrums in distributed condition, and for collectively transmitting said load to said sensing device which then produces a strain or a deformation responsive to said load;
- and
- torsional elastic couplings for coupling said load transmission beams to said outer frame and to said platform mounting members;
- wherein said load sensor comprises a single flat plate.
