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
  • Calibration Chart

Accessories

  • HMA-405 Loading Button threads into load ring mounts to provide a uniform contact point for testing fixtures.

Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
