Beyond the nominal torques being transmitted which can be measured accurately with MagCanica’s torque sensor system, torque variations are ubiquitous in the rotating parts of machines and can be measured with MagCanica’s rate-of-change of torque sensor system. Sensing and measuring variational torque components can often provide more detailed information concerning machine function than might be apparent from a measurement of torque alone, which is often dominated by its larger, more steady-state components. This benefit is analogous to that obtained by using an accelerometer in an airbag sensor system to detect an impending crash, as opposed to a vehicle speed sensor which would not be able to detect a collision rapidly enough or not at all due to the insufficient sensitivity to rapid velocity changes that an accelerometer could detect but a vehicle speed sensor could not.
