Column sensor / SM12A load cell
Product Categories Column sensor
SM12A series weighing sensors use American raw materials and BH series foil strain gauges produced by the proprietary processing technology of BEAN Company of the United States as force-to-electricity conversion elements. The load-bearing method is a compression structure, with good automatic self-aligning function, waterproof and dustproof, easy to install and use, and fully meet the requirements of large-tonnage weighing. It can be used to manufacture electronic truck scales, dynamic track scales, large-tonnage hopper scales, and industrial weighing and level control of large-tonnage silo hoppers.
