Strain gages are bonded on the radial arms of the rear wheel sprocket of a motor cycle to measure the torque on the wheel. A TECAT Telemetry system is installed on the sprocket, to send the straingage signal wirelessly to a receiver, which is connected to a laptop that shows real time torque values on the screen.
Before the test, the gage/transmitter/receiver system is calibrated by applying a known torque on the wheel.
This system allows measurement of torque under actual running conditions of the vehicle, in the lab and in the field.
