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.

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

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

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.

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

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
