At time 3:00 when the animation shows how the shafts rotate, the rotation is in the WRONG direction. When the turbine produces power and the power shaft is loaded the torque causes the torque shaft to lag behind the reference shaft. But the animation shows the blue torque shaft leading the reference shaft. If you would reverse the rotation sense of the animation it would match the given explanation.
@@vasimsaifi2824 The blue torque shaft transmits the torque from the turbine to the reduction gear. The turbine is the "torque input" to the torque shaft, while the connection of the torque shaft to the reduction gear is the "torque output" from the torque shaft. This torque load at the output causes a torsion (twisting around its axis). Therefore the angular orientation of the output side of the torque tube is no longer the same as the angular orientation of the input side (turbine side). The higher the torque load that is output through the torque shaft, the greater is the angular torsion (twisting). The reference shaft gives the "no-load reference" position or angle of the shaft, because the reference shaft is not twisted by any torque load. Therefore the "torque measuring system" can sense a phase difference (or pulse timing difference) between the the two magnets of the respective shafts.
Great video sir
Most beautifully described God Bless You
Do you know the RTD to compensate the thermal effect? And how they are introduced at system? Grate video. Thanks for sharing!

good point
if the reference shaft and torsion shaft are driven by the same gear so how it will lag or lead please explain...

thanks you really helped to present torque measurement in class
thanks for clearing that up! can't imagine mechanical ones being used anymore/
