Torque measurements on the face of a pulley
Torque measurements on the face of a pulley
(OP)
Hi All,
I need to measure the torque on a shaft. Since the shaft surface is not accessible, I want to measure the shear stresses using strain gauges on the face of the flywheel that is attached to one side of the shaft. How should I build a bridge for such measurement?
Thanks

A drawing of the shaft and flywheel would probably be helpful.
A flywheel stabilizes speed by applying torque when the speed changes. If it's not applying torque, it's not doing any good.

Is the strain gauge attached to the thing that it rotating? How do you plan to get the wires off?

One thing to note. Make sure there is sufficient strain in the location you are using the gauge. Most of the time you need to design the 'shaft' or 'pilley' to have this inherent... otherwise you are tying to measure something way into the noise component of the signal.
