Abstract
A speed monitoring system () for a fluid-coupling device () includes a hub () and a ring magnet (). The hub () rotates at a first speed that is proportional to an input clutch speed of a fluidically engageable input member. The ring magnet () rotates at a second speed that is proportional to an output clutch speed of a fluidically engageable output member. A magnetic sensor () generates a differential speed signal of the ring magnet () relative to the first speed. A controller () generates an actual speed signal indicative of the second speed in response to said differential speed signal.
