Enhancing Structural Testing with Multi-Axis Load Cells

Multiple industries use structural tests for quality control, regulatory requirements, failure analysis, predictive maintenance, design and performance verification, and safety assurance.

Structural tests measure the tension, design proofing, and lifecycle fatigue validation. Load cells provide valuable measurement data in structural testing. These tests apply to assessing the structural components for rockets, aircraft, automobiles, EV batteries, heavy equipment, and infrastructure projects.

There are times when more data is valuable beyond a standard load cell. Multi-axis sensors are essential tools for structural testing, providing valuable insights into the behavior of structures under various loading conditions. These sensors measure forces in multiple directions, enabling engineers to identify potential weaknesses, assess structural integrity, and optimize designs.

Multi-axis sensors offer several technical advantages for structural testing compared to traditional single-axis load cells. Interface’s 2-axis, 3-axis, and 6-axis load cells are all excellent options for structural testing.
