Application
Bellow beam load cells are widely used in various industries due to their bellows sealing structure, high precision, and reliable performance in harsh environments.
Platform and Floor Scales
It is commonly installed in electronic platform scales, floor scales, truck scales, and weighing systems for trade settlement, warehouse management, logistics weighing, and vehicle load monitoring.
Hopper and Silo Weighing
Installed under the legs or support rods of hoppers, tanks, reactors, it is used for inventory control, batching and process monitoring of batch production.
Belt Weighers and Conveyor Systems
Integrated into conveyor belts for continuous in-motion weighing, this load cell measures material flow rate and total throughput in mining, aggregates, agriculture, and packaging applications.
Force Monitoring & Process Control
It serves in automated systems for press fitting inspection, tension measurement, industrial automation, assembly line quality testing, and safety overload monitoring in machinery and equipment.
Checkweighing and Sorting Equipment
The Bellow Beam Load Cell is used in-line within automatic checkweighers and sorting machines to ensure product weight compliance in food processing, pharmaceuticals, and consumer goods manufacturing.
Kind Tips
·Installation Requirements: Ensure the mounting surface is clean, flat, and sufficiently rigid to distribute load evenly. Avoid side loads or torsion forces. When using multiple Bellow Beam Load Cells, make sure all are installed at the same height and level.
·Leveling Adjustment: In multi-sensor systems, adjust leveling screws or shims to ensure even load distribution, which is the key to ensure weighing accuracy.
·Overload Protection: Although the load cell offers a safety overload capacity of up to 150% FS, avoid severe shock or prolonged overloading. Install mechanical stops for added protection.
·Electrical Connections: Use shielded cables with reliable grounding to minimize EMI. Secure cables to avoid tension on the connector. Follow wiring instructions (e.g., Exc+, Exc-, Sig+, Sig-) precisely.
·Maintenance & Inspection: Regularly check for corrosion, damage, or loose components. Inspect cables for wear, especially in humid or corrosive environments. Increase frequency of inspection under harsh conditions.
