Abstract
A device for sensing velocity variations in a conductive body 10 moving through a magnetic gap,between two discrete portions,of a magnetic circuit,. The magnetic circuit,generates a magnetic flux,in the gap,to induce eddy currents,in the body,moving through the gap. The device includes an eddy current sensor defining at least one further gap,through which the body,is also moved, and at least one sensor coil,. A voltage is induced in the coil by variations in the induced eddy currents. The voltage is detectable; providing an indication of variations, that is to say accelerations or decelerations, in velocity by providing two discrete magnetic circuit portions, the size and weight of the device be reduced while enhancing the ability to sense eddy currents. The device may be used in a vehicle to sense vibration, acceleration, or other motion.
