Why Interface is Better

  1. 1. We are #1…The World Leader in High Accuracy Load Cells for Force Measurement
  2. 2. Our Heritage • Family owned in Scottsdale, AZ since 1968 • World’s largest manufacturer of low profile load cells • Guarantee: Our load cells will outperform our competitor’s – PERIOD! • Made in the USA
  3. 3. Trust our Experience • We’ve been in the business of manufacturing load cells for 40 years • NIST is the Government standard for measurement traceabilty: They use Interface • Average annual shipments of 40,000 units
  4. 4. Performance Second to None • Metrology grade load cells with accuracy as high as 0.02% F.S. in capacities up to 50K • Lower load limit of 4% on Gold Standard series cells and 2% on Platinum Series • A2LA Accredited calibration
  5. 5. We Sell Solutions • Application engineers will discuss your application to understand your priorities in your force or torque measurement • We will propose a solution specific to your application be it a standard, modified or custom design • This has been our approach for 40 years…there’s a good chance we already have a solution to meet your needs
  6. 6. Vast Capabilities • Accuracy: as high as 0.02% F.S. • Capacity: 50 grams to 2M lbs • Millivolt, Voltage or Current output available • Hermetically sealed, submersible, vibration rated, dual bridge, overload protected • ATEX approved for hazardous environments • 200 page catalog represents 60 – 70% of our business. The rest is modified standard or custom
  7. 7. Over 100,000 configurations of load & torque cells
  8. 8. Why Interface is Better? • Proprietary Interface Strain Gages • Made in house at our facility in Scottsdale, AZ • Feature: Interface strain gages precision matched to counteract the temperature characteristics of the modulus of the load cell structural material • Benefit: The output temperature insensitive and does not require compensation resistors which produces simpler and more reliable circuit.
  9. 9. Why Interface is Better? • Feature: Proprietary Interface Strain Gages • Benefit: Modulus compensation resistors cannot be thermally connected with the cell’s flexure which results in dynamic thermal performance, resistance to thermal gradients, and delayed thermal response
  10. 10. Why Interface is Better? • Feature: Proprietary Interface Strain Gages • Benefit: Our strain gages provide higher output 4mV/V • Competitors provide 3mV/V or less • Benefit: Higher signal-to-noise ratio • Interface uses a minimum of 8 strain gages on each load cell. Most competitors use only 4
  11. 11. Why Interface is Better? • Feature: Rigorous Temperature Testing • Interface performs both hot and cold thermal compensation from 15˚ - 115˚F • Most competitors provide only the hot side (60˚ - 160˚F) • Benefit: The slope of the curve is much flatter near room temperature and identical at both ends of the slope. The result is minimal variation across the entire thermal range.
  12. 12. Why Interface is Better? • Feature: Moment compensation • Interface compensates every low profile load cell • This is accomplished by grinding of each flexure • Competitors do not know the performance in this regard
  13. 13. MOMENT TESTING & COMPENSATION Eccentric & Side Load Specifications
  14. 14. Recap: Interface makes the best cells in the world. Here’s why… Interface makes our own proprietary strain gages. No one else in the industry can say this Every low profile load cell is moment compensated to provide insensitivity to off axis loading Standard Hot & cold thermal compensation: Provides superior performance with temperature gradients Strain Gages Hot & Cold T.C. Moment Compensation
