Torsion & Twist is a specialized software module within the OROS NVGate platform designed for the precise measurement and analysis of torsional vibrations and shaft twist in rotating machinery. It utilizes high-speed, non-contact optical fiber sensors and advanced signal processing algorithms to achieve angular resolution as fine as 0.0001° at speeds up to 10,000 RPM. The software supports both real-time and post-processed analysis, providing instantaneous angular velocity, twist angle, and torsional vibration spectra using FFT and synchronous order analysis. Key features include shaft view visualization, cross-phase tracking for identifying torsional resonances, and compatibility with a wide range of industrial applications such as marine propulsion, wind turbines, power generators, and automotive drive trains. The system is designed for integration with OROS analyzers and can be customized for specific measurement environments.
