When you leave on a journey and look at a map, how do you know how far you have traveled without knowing the exactly where you started? The torque shaft twists with the forces of the engine spinning one direction, and the propeller trying to slow the engine down. The more power the engine puts out, the more the shaft twists. How would you measure it though, without knowing what an un-twisted shaft looks like? This is why we have two shafts. One shaft transmits the torque, and twists while doing it, and the other shaft is a reference for the original, zero torque position. The bigger difference between the twisted shaft and the untwisted shaft, the larger the torque required to make that difference, and the higher reading we get on the indicator.

Thanks man.  That very clear and pro.  

Hi guys , 

why the torque indicating system have two shaft , torque shaft and reference shaft ?   

Can any one help me
