I have a magnet coupled to a gearbox with a relationship of 13000 rpm:1, I need to measure torque in the gearbox. I was trying to measure it with strain gauges but the device is very small (1.5 cm diameter tops) and the accuracy is almost none. I know that Hall sensors would help me on this but to be honest I don't know how to couple them. (Torque is going to be small, approximately from 0.002 mNm to 1.5 Nm)
