Abstract
Abstract The invention relates to a weighing element for a weighing apparatus, comprising an elongated plate-shaped ceramic bending element (1) provided with strain-gauge transducers, one end (2) of the bending element being secured to a frame (6) of the weighing element, the free other end being secured to a torque lead-in arm (10), said bending element being supported by the frame and by the arm at a distance a from said one end and said other end, respectively. In order to increase the accuracy of the weighing element it is proposed to make the frame and arm supports (8, 13) resilient in the longitudinal direction of the bending element.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
146 words
A weighing element for a weighing apparatus comprising a frame; a bending element having one end and a top and bottom surface and strain-gauge transducers mounted thereon; said bending element having its top surface secured to said frame at said one end; said bending element having a free end; a force-transmitting arm with a first end secured to the bottom surface of said free end of said bending element; support means for said bending element and said force-transmitting arm; said support means for said bending element contacting said bottom surface of said bending element; said support means for said force-transmitting arm contacting the top surface of said bending element; pin means on said force-transmitting arm through which forces are applied thereto to cause said bending element to bend; said support means having resiliency and bending when said bending element is being bent by an applied force.
Claim 2
Dependent Claim
146 words
A weighing element for a weighing apparatus comprising a frame; a bending element having one end and a top and bottom surface and strain-gauge transducers mounted thereon; said bending element having its top surface secured to said frame at said one end; said bending element having a free end; a force-transmitting arm with a first end secured to the bottom surface of said free end of said bending element; support means for said bending element and said force-transmitting arm; said support means for said bending element contacting said bottom surface of said bending element; said support means for said force-transmitting arm contacting the top surface of said bending element; pin means on said force-transmitting arm through which forces are applied thereto to cause said bending element to bend; said support means having resiliency and bending when said bending element is being bent by an applied force.
Claim 3
Dependent Claim
20 words
