Fundamentals of Fatigue Life Prediction
Interface load cells accurately quantify the forces applied during fatigue testing for predicting failure. Fatigue refers to the weakening of material caused by repeatedly applied loads. Failure occurs after a certain number of cycles, even when the stresses are well below the material's ultimate tensile strength. While an accurate prediction of fatigue life is not a reality, theoretical analysis and empirical data allow for useful approximations to estimate the margin of safety for a given design.

Resistance Output Versus Rated Output
Rated Output (RO) is the dynamic electrical signal that directly represents the applied mechanical force. Resistance Output is a static electrical characteristic of the load cell's internal circuitry. When you are performing force measurements, you are primarily interested in the Rated Output. This value, in conjunction with your excitation voltage, enables you to accurately convert the measured millivolt signal into engineering units of force in lbf or Newtons.

Side Load Sensitivity 101
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.

Load Cell Flexures 101
Interface designs all of our load cell flexures. A flexure is a specially designed component that can bend under a load without breaking. They are used in sensors where precise, frictionless movement is needed, like measuring force. The flexure, a complex machined part, acts as the spring element. With thousands of models, capacities, and configurations, manufacturing our flexures is paramount to our load cell accuracy, quality, and precision performance.

Understanding and Preventing Load Cell Overload
Interface offers patented overload protection for load cells. Overload detection is crucial for maintaining load cell accuracy. Properly detecting and handling overload conditions can prevent permanent damage and ensure the sensor's longevity. By understanding the signs of overload, managing impact loads, and employing preventive measures, users can maintain the integrity of their measurement systems. Regular maintenance and proper design considerations are vital to avoiding the detrimental effects of overload and ensuring accurate, long-term performance of load cells.

Low Profile Load Cells versus Simple Single Column Load Cells
The Interface LowProfile Load Cell, a pancake design, is dramatically better than the simple single column cell in every respect. The low profile design outperforms the single column design. The overall proprietary Interface LowProfile design is more compact, with all the components bonded to the flexure structure, making it better able to withstand the 100 million-cycle fatigue life. Our standard 1200 “Blue” LowProfile Load Cell is the most popular load cell in the market and is used in testing labs and industry applications worldwide.
