Column load cell / SM-S4A column load cell
Product Categories Column sensor
SM-S4A 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-electric conversion elements. The load-bearing method is a compression structure, with good automatic self-aligning function, waterproof and dustproof, easy to install and use, which fully meets 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 material level control of large-tonnage silo hoppers.
