Compression Testing for Mechanical Evaluations

Interface load cells for compression testing provide data for mechanical evaluations to determine how materials, components, and complete structures behave under opposing axial pushing or crushing forces. Transducer data in compression analysis define success and failure across industries, from robotics to aerospace.

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.

Transducers for Aircraft Ground Support Equipment Design and Operations

Accurate measurement of force and torque transforms ground support from reactive repairs to proactive, condition-based lifecycle management. Whether installing new hardware or upgrading existing equipment with direct-fit load pins, tension links, and load cells, continuous force, torque, and weight monitoring safeguards aircraft and ground personnel from unnoticed structural stresses, equipment failures, and overloading.
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.

Rigging

The Mechanics of Suspended Loads in Heavy Rigging

Interface products provide real-time measurements of cable tension and load weight to prevent dangerous overloads of rigging equipment. Rigging converts rotational, linear, or gravitational forces into controlled mechanical displacement. It relies on calculating vector forces, tension distribution, centers of gravity, and safe working load (SWL) limits to ensure that heavy components remain structurally stable and balanced throughout dynamic motion.
Types Of Testing IMPACT

Impact Testing for Millisecond Assessments

Interface impact testing force measurement solutions are used in material, component, and product tests, from sports equipment to autos and aircraft. High-velocity impact testing demands high-velocity sensors and low-latency instrumentation to capture millisecond-long force spikes without data gaps or signal clipping. Pairing the load cell and instrument is critical for a successful impact testing system.
Strain Versus Stress

The Divergence in Force Measurement of Strain Versus Stress

Interface details stress testing versus strain testing using force measurement sensors to quantify material deformation and internal resistive forces. Distinguishing between stress and strain is critical for defining test parameters, selecting sensor capacities, and interpreting data from a material’s elastic and plastic regions.
Subzero

Subzero Force Measurement to Manage the Chill Effect

Interface load cells are used in subzero testing, ranging from heavy machinery to consumer products. Load cell design, rigorous calibration, and temperature compensation are critical for thermal cycling, enabling it to transition repeatedly from extreme cold to room temperature without losing sensitivity or structural integrity. From ski equipment to wearables to energy and aerospace equipment. Interface provides load cells to use in subzero environments.
Wing Testing

Aircraft Wing Testing Requires Force Measurement Accuracy

Interface offers force measurement solutions for testing aircraft wings in static load tests and complex, multi-year simulations of an aircraft’s entire operational lifespan. Engineers and manufacturers use Interface fatigue-rated load cells in wing tests requiring millions of cycles. Aerospace testing labs use load cells and multi-axis sensors to conduct complex wing testing on drones, UAVs, defense aircraft, and commercial airplanes.
