Column Sensor/ SM4-ST Column Sensor
Product Categories Column sensor
SM4-ST series column load cell uses American raw materials and the BAB series high temperature foil strain gauge produced by the proprietary processing technology of BEAN Company of the United States as the force-electric conversion element. The load-bearing mode 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 is widely used in major oilfield pumping wells, light rod force measurement, truck scales, track scales, large-tonnage hopper scales, and industrial weighing and material level control of large-tonnage silo hoppers and other metering equipment.
1. Overview
SM4-ST series column load cell uses American raw materials and BAB series high temperature 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, and fully meets the requirements of large-tonnage weighing.
It is widely used in major oilfield pumping wells bare rod force measurement, truck scales, track scales, large-tonnage hopper scales, and industrial weighing and material level control of large-tonnage silo hoppers and other metering equipment.
