Overview
We engineered a torque monitoring system for a turbine operating in water. With no existing method available, we explored two possible approaches: a modern torque transducer or a dynamometer. After evaluating both, we chose the transducer for its affordability, compact size, and low power requirements. The final system combined an agricultural PTO, stock bearings, and custom-machined components to measure torque accurately under load. It delivered reliable, fully mechanical performance without the need for electronic control.
Methodology
The project began with detailed research and consultations with external torque measurement specialists. Our team compared the transducer and dynamometer methods, evaluating precision, power requirements, and cost. After selecting the transducer approach, we designed and machined bespoke components to integrate the system. When machining issues arose, we carried out on-site adjustments at a local machine shop to maintain alignment, meet deadlines, and uphold quality standards.
Results Discussion
Our team delivered a fully functional torque monitoring rig that performed reliably under load with no failures. Precision engineering and proactive problem-solving allowed the system to meet all requirements. Key takeaways included the value of early research, collaboration with external experts, and adaptability during manufacture and assembly. The project demonstrated how careful design and on-site intervention lead to reliable, high-performing mechanical systems.
