Interface 101 series highlights cycle testing, which uses load cells, torque transducers, and multi-axis sensors to evaluate functional reliability, kinematic wear, seal integrity, switch actuation life, joint loosening, and mechanical degradation across hundreds, thousands, or millions of operating cycles. Cycle testing is an evaluation methodology used to verify product endurance, track mechanical wear, and establish operational life expectancy under repetitive dynamic loading.

Interface 101 highlights the side force effect, side load sensitivity, and eccentric load sensitivity. Side load sensitivity is how a load cell's output is influenced by a side force. It reveals the load cell's sensitivity to forces applied off its intended axis. A side force effect in compression testing with load cells refers to a force applied perpendicular to the intended axial compression force. This can happen due to misalignment between the load cell under test and the testing machine's loading plates.

Fatigue testing requires accurate and reliable force measurement. Interface fatigue-rated load cells are designed to withstand the rigors of repeated loading, which makes them ideal for even the most demanding high cycle count fatigue testing applications. Interface uses 'fatigue-rated' as an exact specification that defines a special class of load cell design and construction.
