Description

Technical Field

[0001] The utility model relates to the technical field of weighing sensors, in particular to an S-type hook scale weighing sensor. Background Art

[0002] Crane scales are often used for industrial lifting operations, while S-type load cells have a wide range of applications in both enterprise and laboratory measurements. Existing lifting equipment generally uses the two in combination to increase its functional diversity. However, in the existing technology, skew and non-vertical conditions often occur during the lifting (or weighing measurement) process, making it difficult for operators to intuitively see the data. At the same time, when multiple S-type load cells are stacked together, some testers need to customize the angle to detect force conditions in different directions, which is impossible for existing technical solutions to achieve.

[0003] Therefore, there is an urgent need for an S-type hook scale weighing sensor that can detect whether it is vertical during the weighing process and measure the force conditions at multiple angles when used in superposition. Utility Model Content

[0008] Furthermore, the pointer protrusion is circular in shape and a rectangular protrusion is provided on the circumferential edge.
