Designed to accurately measure engine output or transmission input shaft torque, the MagCanica engine output / clutch shaft torque sensor system is currently used at track tests and races to optimize internal combustion engine, motor-generator unit, and gearbox performance, and is often mandated for use by automotive regulating bodies. The torque-sensor does not contact the shaft but utilizes a small radial gap of typically 2mm. Sensitivity to axial movement can be minimized with standard machining tolerances.
Typical nominal torque ranges are approximately 600Nm with overloads up to 1500Nm, while rotational speeds can range from 0 RPM to as high as 20,000 RPM. High reliability and robustness allow the system to survive the very harsh transmission input environments, which are often characterized by very high temperatures, vibration levels, and the presence of oil (either wetted or submerged).
