This solution can be used to measure rotating torque using non-rotating torque sensor which has two mounting flanges,one flange for torque sensor installation and the other to be connected with the motor flange, motor shaft goes through the center hole of the transducer,the torque caused by the rotating blades is transfered to the motor through the shaft,then the torque transducer measures the reaction torque caused by the motor. No extra rotating parts are involved to deliver stable torque measurement results.This measuring configuration is more cost-effective and durable compared to rotating type torque sensors.You may find it applicable for fastening torque monitoring, agitator stirring torque control, servo motor torque measurement, wrapping Torque test and so on.
