Component Specifications

Definition
The load cell body/dancer arm is a critical structural component in tension sensing systems, typically consisting of a rigid arm or frame that supports the load cell transducer. It mechanically interfaces with moving material (web, wire, filament) through rollers or guides, transmitting tension forces to the strain gauge elements within the load cell. This component ensures accurate force measurement by maintaining proper alignment and minimizing extraneous forces that could affect measurement accuracy.
Working Principle
The dancer arm pivots or deflects in response to material tension changes, transferring this mechanical force to the load cell's strain gauges. These gauges experience resistance changes proportional to the applied force, which are converted into electrical signals for tension monitoring and control systems.
Materials
Typically manufactured from high-strength aluminum alloys (e.g., 6061-T6, 7075-T6) or stainless steel (e.g., 304, 316) for corrosion resistance and structural integrity. May include hardened steel bushings at pivot points and anodized or powder-coated finishes for environmental protection.

Frequently Asked Questions

What is the difference between load cell body and dancer arm configurations?

Load cell bodies are typically fixed structures that directly support the transducer, while dancer arms are pivoting or floating arms that follow material movement and transfer tension forces to the load cell. Dancer arms provide continuous tension measurement during material feed variations.

How do I select the right material for my application?

Choose aluminum alloys for lightweight applications with moderate corrosion resistance, stainless steel for harsh environments or higher load requirements, and consider special coatings for chemical exposure. The material must provide sufficient stiffness to prevent deflection errors while minimizing inertia effects.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
