TorqueSense Preferred Option For INS Vikrant for Accurate Torque And Power Measurement


The INS Vikrant is India’s first indigenously built aircraft carrier. It is powered by two shaft lines each of 44MW. The Navy was seeking a reliable solution for torque and power measurement. The Navy’s experience with traditional strain gauge-based systems has been unsatisfactory.Neptunus’ solution is based on employing two Magnetic Pick up units. The system has no moving parts, is rugged and simple to deploy. Accuracy of the system is =/-1%
