In the intricate realm of test and measurement, Interface knows that precision is paramount. When the forces at play involve axial (pushing or pulling) and torsional (twisting) loads, a specialized sensor device is required to capture the complex interplay of these forces. That is what is known as an axial torsion load cell.
What are Axial Torsion Load Cells?
An axial torsion load cell is an advanced sensor engineered to measure axial force and torsional torque simultaneously. These load cells, often categorized as multi-axis sensors, have the dual measurement capability that sets them apart from traditional load cells, which typically measure only one type of load.
They achieve this by incorporating strain gages strategically placed to detect both the compression or tension resulting from axial force and the shear strain caused by torsional torque.
How Do Axial Torsion Load Cells Work?
The core principle behind axial torsion load cells is the relationship between strain and electrical resistance. When the load cell is subjected to axial force or torsional torque, it experiences deformation. This deformation, in turn, causes a change in the electrical resistance of the strain gauges embedded within the load cell's structure. By measuring this change in resistance, the load cell's electronics can accurately calculate the magnitude of the axial force and the applied torsional torque.
Why Choose a 2-Axis Axial Torsion Load Cell?
Axial torsion load cells play a crucial role in various test and measurement applications where the simultaneous measurement of axial force and torsional torque is essential for understanding the behavior of materials, components, or systems under complex loading conditions.
The top three reasons for selecting a load cell that can simultaneously measure force and torque.
#1 Improved Accuracy: Traditional methods of measuring axial force and torsional torque often involve separate sensors, which can introduce errors due to misalignment or inconsistencies in measurement points. Axial torsion load cells eliminate this issue by providing a single, integrated solution for measuring both loads.
#2 Comprehensive Data Collection: By measuring axial force and torsional torque, these load cells provide a complete picture of the forces, enabling engineers and researchers to gain deeper insights into their performance and potential failure modes.
#3 Effectiveness: The ability to measure both loads with a single sensor simplifies the test setup, reduces the number of components required, and streamlines the data collection process, resulting in improved efficiency and cost savings.
Axial Torsion Applications
Their ability to provide accurate and comprehensive data with a single, integrated sensor has revolutionized how we test and evaluate materials, components, and systems across various industries. The versatility of axial torsion load cells makes them suitable for a wide range of applications across various industries, including:
Automotive Industry: Testing automotive components such as steering systems, drive shafts, and suspension systems to ensure their durability and performance under combined axial and torsional loads.
Aerospace Industry: Evaluation of aircraft structures and components to assess their structural integrity and response to complex loading scenarios encountered during flight. For example, an aircraft manufacturer wants to measure the torque of their yoke or control wheel. Interface suggested using the AT103 2-Axis Axial Torsion Load Cell to measure torque and force within this single sensor. Check out the application here.
Manufacturing Industry: Quality control and testing of fasteners, bolts, and other components subjected to axial and torsional loads during assembly and operation.
Biomedical Research: Measurement of forces and torques applied to joints and implants to assess their performance and design optimization.
