Abstract

PURPOSE: To reduce manufacture processes in number and also to improve precision by providing two strain gauges to a cell in a parallelogram frame shape and then by canceling an error that it generates by that generated by losing the parallelism of opposing parallel parts as much as fixed.
CONSTITUTION: Load cell 20 is formed of lateral parallel parts (a) and (b) and longitudinal parallel parts (c) and (d); strain gauges (r1) and (r3), and (r2) and (r4) nearly equal in resistance value are stuck at two points on the external surface of its narrow part, and built into a Wheatstone bridge circuit. The, longitudinal parallel part (c), for example, is fixed and parallel load W operates upon longitudinal parallel part (d). In this case, although variation in output E is in proportion to that in load when eccentric value (e) is zero, it is not in proportion when eccentric value (e) is not zero. For the purpose, a proportional relation between output E and load W is compensated by an error generated by putting lateral sides (a) and (b) out of parallel. In this way, manufacture processes are reduced in number and precision can be improved.
