business. The rest is modified standard or custom

7. Over 100,000
configurations of load &
torque cells

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. 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. 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. 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. 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

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
