5-Axis Load Cells 101

An Interface 5-axis load cell is a multi-axis sensor designed to resolve complex multi-directional loading into three orthogonal forces and two bending moments (Fx, Fy, Fz, Mx, and My). By combining multiple sensing elements into one precisely machined structure, a 5-axis load cell provides comprehensive measurement of complex loading conditions that conventional single-axis load cells cannot accurately capture. Learn more in 5-Axis Load Cell 101, part of Interface's 101 Series.

Understanding Dual Shear Load Cells

Interface dual shear load cells are strain gage sensors supported at both ends, with the force applied directly at the center of the beam. A double-ended shear beam load cell design is used in the high-performing Interface LowProfiles and load pins. The dual-ended design distributes force symmetrically across two matched shear webs. Strain gages are bonded to the machined webs inside the beam and configured in a full Wheatstone bridge circuit to convert mechanical shear stress into an electrical mV/V signal.
Moment 101

Moment 101

Interface's 101 Series defines moment as the measure of a force's tendency to cause rotational movement, bending, or tilting when applied at a distance from a fixed point or axis. In force measurement, moment is the physical displacement or rotation that occurs when an unbalanced force acts on an object, and measuring moment in multi-axis sensors provides critical data for a variety of industry applications.

Natural Frequency 101

Natural Frequency 101

Interface Natural Frequency 101 defines the inherent rate at which a sensor oscillates when allowed to vibrate freely. Learn how natural frequency and deflection affect dynamic force measurement, how to avoid resonance, and engineering tips for optimizing load cell accuracy. Natural frequency serves as the definitive boundary for the bandwidth of a force measurement system and for structural integrity. Accurate data acquisition from load cells relies on maintaining a clear separation between the application's operational frequency and the resonant frequency of the physical test loop.
Temperature Compensation 101

Temperature Compensation 101

Interface's 101 Series details load cell temperature compensation, why temperature compensation matters, and key specifications. Prioritizing temperature compensation minimizes measurement uncertainty, leverages the repeatability of thermal shifts, and ensures that test results reflect true mechanical loading rather than environmental interference.
Data Sheet 101

Interface Data Sheet 101

Interface Data Sheet 101 reviews what to expect from our technical product data sheets. Consider data sheets as a technical roadmap of mechanical and electrical performance information. Interface data sheets include features, a reference image, performance specs, and drawings. The characteristics defined on a product data sheet are used to distinguish successful validation from a system failure by highlighting the individual model's specifications, dimensions, diagrams, characteristics, connectors, and wiring, when applicable.
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.
Elasticity 101

Elasticity 101

Interface's Elasticity 101 details the importance of Hooke's Law of Physics. In a load cell, we want a material with a very predictable stiffness. If the material permanently deforms or creeps, the deformation value won't return to zero, and your measurements will be inaccurate. A load cell is essentially a mechanical transducer that converts mechanical force into elastic potential energy, which we then capture as data. Understanding how your sensor bends is the first step toward mastering precision force measurement. Learn more in Interface's ForceEDU 101 Series.
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.
