Load Rings, often referred to as proving rings, are manufactured from high-strength aluminum alloy with repeatable elastic deformation characteristics and are used to determine force measurements. Loads are measured with an accuracy of ±0.5% using the included mechanical dial indicator with 0.0001in resolution. A calibration chart to derive force values based on ring deformation is also included.

Load Rings are available in eight different capacities ranging from 250 to 10,000lbf and have a mounting hole size of 1/2inx20tpi, making them compatible with Gilson and other manufacturers' load frames and direct shear units.

Features

  • Optimal for measuring applied force in laboratory testing
  • Accurate to ±0.5%
  • Convenient plotting of force values on the included calibration chart
  • Wide range of capacities available to fit your application

Included Items

  • Load Ring
  • Mechanical Dial Indicator with 0.0001in resolution

Product Q&A

Specimens longer than 5in are extracted by repositioning the Adapter Ring after maximum piston travel, and the spring-loaded piston automatically returns to the start position when the release valve is opened.
