Description

Technical Field

[0001] The utility model relates to the technical field of weighing, in particular to a column type weighing structure. Background Art

[0002] A column-type weighing sensor is a weighing device with a column-type structure that converts mass signals into measurable electrical signal outputs. The column-type weighing sensor includes a column-type elastomer and a resistance strain gauge. The resistance strain gauge is fixed to the surface of the column-type elastomer to form a Wheatstone bridge. When the load cell is subjected to force to cause the internal column-type elastomer to deform, the resistance strain gauge deforms synchronously, and the weight of the object being measured can be measured. The overall center of the column-type weighing sensor is relatively high, with a greater risk of overturning, and it is easily affected by environmental vibrations, so the weighing accuracy cannot be guaranteed.
