How does a torque sensor work in Garrett engine?

A torque sensor in a Garrett engine measures the torque output of the engine's components, typically using strain gauges that detect deformation in a rotating shaft. As torque is applied, the shaft twists slightly, causing the strain gauges to change resistance. This change is then converted into an electrical signal, which can be processed to provide real-time data on engine performance. The information can be used for various applications, including optimizing engine efficiency and monitoring for potential issues.
