Embodiment Construction
[0041] see figure 1 , 2 3. The small-range load cell 1 has a strain beam 101 that feels the bending normal stress, a small semi-cylindrical bearing head 102 with an enlarged diameter extends from the front end of the strain beam, and a diameter-expanded small bearing head 102 extends from the rear end of the strain beam. A cylindrical fixed seat 103, and a stopper 105 with an enlarged diameter extends from the tail end of the cylindrical fixed seat 103. The small-range load cell strain beam 101 can adopt a conventional rectangular cantilever beam structure, That is, the loading surface of the strain beam 101 is rectangular, and the strain gauge 104 is attached to the strain beam 101 . In order to facilitate installation and replacement, the diameter of the small semi-cylindrical carrying head 102 is preferably smaller than the diameter of the fixing seat 103 .
