Product Specifications

Technical details and manufacturing context for Tension Sensor (Load Cell/Dancer)

Definition
A critical component within the Separator Feeding & Tensioning Unit responsible for real-time measurement of material tension. It ensures consistent, controlled feeding by providing feedback to the tensioning mechanism, preventing material breakage, slippage, or deformation during high-speed manufacturing processes.
Working Principle
Operates by converting mechanical force (tension) into an electrical signal. A load cell uses strain gauges that deform under load, changing electrical resistance proportionally to the force. A dancer system uses a movable roller whose position, influenced by tension changes, is measured via a potentiometer or encoder. The signal is processed by a controller to maintain preset tension levels.
Common Materials
Stainless Steel (Housing/Roller), Aluminum Alloy, Strain Gauges (Nickel-Chromium)
Technical Parameters
  • Maximum measurable tension force (Capacity) (N or kN) Standard Spec
Components / BOM
