Torque Sensors

Daniel Louks, Engine Support Engineer at IZOD Indycar discusses how a torque sensor works. Daniel Louks explains how radio crystals installed in the torque sensor to the input shaft help record frequency response and measure horse power.

The electronics that amount to a radio crystal are installed into the input shaft measure the amount of resistance passing through the engine shaft. As this engine shaft twists, the response begins to change the frequency of the radio crystals in the torque sensor followed by a signal to a controller box. The controller box records the frequency response from the shaft allowing remote measurement of horse power.
