Column load cell / SM4-LZ column load cell
Product Categories Column sensor
SM4-LZ series force-load weighing sensor adopts BH series foil strain gauge produced by American raw materials and processing technology of American BEAN Company as force-electric conversion element. The bearing mode is compression structure. The main body is precision-processed with special steel. It has good automatic self-aligning function, waterproof and dustproof, easy to install and use, and fully meets the requirements of large-tonnage weighing. It can be used to manufacture electronic truck scales, dynamic track scales, large-tonnage hopper scales, industrial weighing and material level control of large-tonnage silo hoppers and primary instruments for force-electric conversion in other special occasions.
