High Fidelity 101

High-Fidelity 101

Interface 101 series details high-fidelity (Hi-Fi), a term referencing how accurately a measurement system reproduces the characteristics of a physical input. Load cell users may require a high-fidelity system where the digital output precisely reflects the mechanical force applied to the sensor. This integrity must be maintained throughout the entire signal chain, from the physical deformation of the strain gage to the final data output. Hi-Fi is very important in aerospace, additive manufacturing, and product efficiency such as lightweighting.
Hysteresis 101

Hysteresis 101

Interface defines hysteresis as the algebraic difference between the load cell's output at a specific load when approached from an increasing direction versus a decreasing direction. Hysteresis represents a physical limit of the sensor's design. Hysteresis is typically expressed as a percentage of Full Scale (%FS) on a sensor's data sheet or calibration certificate. Learn more about this vital characteristic in Interface's Hysteresis 101.
NONLINEARITY 101

Nonlinearity 101

Nonlinearity refers to the deviation from a straight line during a single, continuous loading cycle, which is a percentage of full scale from zero to full load. Interface 101 Nonlinearity details this crucial specification because it directly impacts the accuracy of your measurements. A load cell with a high nonlinearity percentage will give you inaccurate readings, especially at the intermediate points of its measurement range.

Lowprofile Mounting No Base

Mounting LowProfile Load Cells Without an Interface Base

Interface answers how to mount a LowProfile Load Cell without a factory-installed base. Direct mounting a load cell onto a structure should precisely reproduce the mounting used during its calibration. This ensures that the sensor operates under the same mechanical constraints and material interactions for which its performance specifications were validated.
Consider Overload Protection

Key Considerations for Overload Protection in Load Cells

Overload significantly threatens the accuracy, longevity, and safety of force measurement systems. An overload occurs when the force exerted on a load cell surpasses its designated capacity limit. Discover how Interface load cells incorporate innovative features to reduce the risks associated with overloading. Interface offers a number of standard LowProfile and Mini load cells with overload protection.
