Power measurements are performed at the propeller shaft. Strain gages and a RPM sensor are installed to measure the shaft-torque and shaft-rotation. Both signals are logged by a data acquisition (DAQ) system.
Used measuring instruments;
- Vishay CEA-06-250US-350 strain gages ± 0.4%, 350 Ω.
- TorqueTrak 10K, digital telemetry system (Binsfeld, USA)
