The torquemeter for the turbine works by measuring the twist of the coupling spacer made with integral teeth. The system has multiple pickups in the form of internally toothed rings. As the shaft rotates, its teeth cut the flux and generate a sinusoidal voltage in each coil. The torque required to twist the shaft through one tooth pitch would correspond to a 100% phase displacement. An electronic readout device then converts the speed and phase measurements into torque.
