The operation principle of each combination type LOAD CELLS is:
The pressure that mounting seat affords self all passes to the gusset piece portion of upper supporting part by the first precision LOAD CELLS；Upper supporting part is in free state namely when not bearing pressure, and it is led power pressure contact portion and exceeds power of the leading support of lower supporting part；
Compression spring during upper supporting part pressure-bearing stress thus move down, when mounting seat pressure-bearing stress is less than 5 kilogram, namely time in the first rank range ability, by selecting suitable spring and selecting suitable power of leading pressure contact portion and lead the spacing of power support, during so that weigh in this rank range, the power pressure contact portion of leading will not be crimped onto and cause on support, now gusset piece portion suffered by self all pressure transmission give the second precision LOAD CELLS, during Gai, first precision LOAD CELLS and the second precision LOAD CELLS all bear whole pressure, but external display screen only shows the data that the second precision LOAD CELLS measures, its accuracy value is the accuracy value that the second precision LOAD CELLS has, in the present embodiment, accuracy value in this range is 1 gram；
When mounting seat pressure-bearing stress is less than 50 kilograms and is more than or equal to 5 kilogram, namely time in second-order range ability, the power pressure contact portion of leading can be crimped on leads on power support, the pressure that now the gusset piece portion of upper supporting part bears, only having sub-fraction and pass to the second precision LOAD CELLS, remaining major part is then directly passed to by leading power pressure contact portion on power of the leading support of a spike；Due to during this, first precision LOAD CELLS bears whole pressure, so external display screen only shows the data that the first precision LOAD CELLS measures, its accuracy value is the accuracy value that the first precision LOAD CELLS has, in the present embodiment, the accuracy value in this range is 100 grams；In this second-order range ability, the deformation of spring no longer increases, namely the pressure that the second precision LOAD CELLS is born is in preset range, so that the second precision LOAD CELLS will not damage because of overweight during Gai.
