6-Axis Force Sensors for Multi-Directional Load Measurement

The 6-Axis Force Sensor is an advanced measurement device designed to simultaneously measure forces and moments along six degrees of freedom—three orthogonal force components (Fx, Fy, Fz) and three corresponding moments or torques (Mx, My, Mz). This capability allows engineers to capture the complete load state acting on a component or structure in real time, providing insight that single-axis or multi-sensor setups cannot deliver with the same accuracy or synchronization.

Six-axis force sensing is essential in applications where loads are complex, multi-directional, and dynamically changing. By measuring all force and moment components at a single point, the sensor eliminates alignment errors and time offsets that can occur when using multiple discrete sensors.

Measurement Principle

6-axis force sensors typically use strain gauge technology arranged in a carefully engineered elastic structure. When external loads are applied, the structure deforms in a controlled manner. Strain gauges positioned at specific locations detect these deformations and convert them into electrical signals.

Through calibration and matrix-based signal processing, the sensor decouples the measured strains to accurately resolve each force and moment component independently. This decoupling process is critical for achieving high accuracy and low cross-axis interference, even when loads are applied simultaneously in multiple directions.

Key Characteristics

6-axis force sensors offer high accuracy, strong linearity, and excellent repeatability across all measured axes. They are designed to withstand complex loading conditions while maintaining stable output and low hysteresis. Compact designs allow integration into test rigs, robotic end-effectors, fixtures, and mechanical assemblies where space is limited.

Robust construction supports operation in environments exposed to vibration, temperature variation, and continuous loading. The sensor’s ability to measure forces and moments simultaneously makes it particularly valuable for dynamic testing and real-time control applications.

Typical Applications

6-axis force sensors are widely used in:

• Robotics and automation, measuring interaction forces and torques at end-effectors

• Industrial testing and validation, capturing complex load conditions on components

• Aerospace and automotive testing, analyzing multi-directional forces and moments

• Biomechanics and ergonomics, measuring interaction forces in research and testing

• Precision assembly and machining, monitoring force and torque during operations

In these applications, full six-degree-of-freedom data enables deeper understanding of system behavior, load paths, and mechanical interaction.

System Integration

6-axis force sensors integrate seamlessly with Dynatronic data acquisition and control systems. When combined with displacement, vibration, speed, or temperature measurements, force and moment data provides a comprehensive view of mechanical performance. This multi-parameter approach supports advanced diagnostics, design validation, and closed-loop control strategies.

Complete Load Insight in a Single Sensor

By delivering synchronized measurement of all force and moment components, the 6-axis force sensor provides a powerful and efficient solution for complex load analysis. Its accuracy, robustness, and integration flexibility make it an essential tool for engineers who need reliable multi-directional force data in demanding industrial and research environments.
