High-Capacity Loadcell Testing System

High-Capacity Loadcell Testing System (6 MN) with Allen-Bradley ControlLogix PLC

In response to growing industry demands for precision and scalability in high-force measurement systems, our engineering team successfully delivered a state-of-the-art Loadcell Testing System capable of handling forces up to 6 Mega Newtons (MN). This advanced solution is built around the robust and reliable Allen-Bradley ControlLogix PLC platform, ensuring high performance, seamless integration, and long-term scalability.

Customer Challenge:

The client—an international manufacturer of heavy-duty loadcells and force transducers—faced challenges in:

•Validating large-capacity loadcells under real-world force conditions (up to 6 MN).

•Meeting increasingly strict calibration standards for high-force applications.

•Automating test sequences with real-time data acquisition, diagnostics, and reporting.

•Ensuring safety and redundancy during high-force testing procedures.

Our Solution:

Our team designed and implemented a turnkey Loadcell Testing System featuring:

•Test Capacity: 0–6 MN compressive force range.

•Automation Platform: Allen-Bradley ControlLogix PLC with integrated motion, safety, and analog I/O modules.

•High-Precision Analog Input Modules: For accurate signal acquisition from the DUT (Device Under Test) and reference loadcells.

•HMI & SCADA Integration: Intuitive interface using FactoryTalk View SE, offering real-time monitoring, parameter tuning, and historical data logging.

•Safety Systems: Integrated using GuardLogix safety PLC functions with emergency stop, overload protection, and safe motion interlocks.

•Test Control Algorithms: Developed for closed-loop control with real-time force feedback and PID tuning.

Outcome & Impact

•Increased Throughput: Automated test sequences reduced test cycle times by over 35%.

•Compliance: Fully aligned with ISO 376 and ASTM E74 standards for loadcell calibration.

•Reliability: Continuous testing uptime >98% since deployment.

•Client Feedback: “The ControlLogix-based system has brought unprecedented control, safety, and reliability to our testing process. It’s a future-ready platform that positions us for growth in ultra-high-capacity sensor manufacturing.”

Conclusion

This project exemplifies how a well-integrated automation solution using Allen-Bradley ControlLogix can deliver high accuracy, reliability, and user-friendly operation—even in demanding applications like 6 MN loadcell testing. By combining deep domain expertise with cutting-edge control technology, we helped our client modernize their testing capabilities and position themselves as a leader in high-force sensor validation.
