Column load cell / SM4 column load cell
Product Categories Column sensor
SM4 column weighing sensor uses American raw materials and BH series foil strain gauges produced by American BEAN company processing technology as force-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, fully meeting the requirements of large tonnage weighing, and 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. SM4F: integrated standard voltage output SM4B: integrated standard current output.
1. Overview
SM4 column load cell adopts American raw materials and BH series foil strain gauges produced by American BEAN company's processing technology as force-electric conversion elements. The load-bearing mode 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 level control of large-tonnage silo hoppers.
SM4F: Integrated standard voltage output SM4B: Integrated standard current output.
