The manufacturing process of the pin shaft structure is exactly the same as that of other structural load cells, but because the double shear type resistance strain gauge is pasted in the deep hole, it is necessary to purchase and design special sandblasting treatment, scribing patch, pressure curing tools and equipment .
Detection and application technology of pin load cell sensor
Since the pin load cell sensor itself is an integral elastic element, that is, there is no protective shell, no loading pressure head and bearing base, so when testing and calibrating, the same boundary support as that used in actual installation and use should be used, that is, the same support.
The pin-type load cell sensor is a special load cell sensor for measuring the radial load of bearings, pulleys and other components or the tension of steel wire ropes. It can replace the pulley pin and be installed in the structure for longitudinal force measurement. According to different purposes, hooks, rigging shackles, movable pulleys (sets), fixed pulleys (sets), wedge joints, steel cable sockets, marine rigging, open turnbuckles, and tie rod heads are conveniently installed at the joints of two metal structures. It can not only replace the original shaft, but also play the role of weighing force sensor, so that the whole weighing force control system The mechanical parts are greatly simplified.
In recent years, the pin load cell sensor has been mainly used in the field of electronic crane scales, and it is common to be assembled into quantitative or wireless transmission electronic crane scales by cooperating with U-shaped lifting rings. Since the pin shaft is directly assembled with the suspension ring and the suspension hook, not only the load-bearing shell with complex structure is omitted, but also the assembly precision can be improved to ensure the weighing accuracy.
