Abstract
1518165 Measuring wear BURMEISTER & WAIN'S MOTOR O G MASKINFABRIK AF 1971 A/S 18 Sept 1975 [20 Sept 1974] 38365/75 Heading G1N A measuring probe for measuring the wear in the cylinder wall 8 of a diesel engine comprises a central, cylindrical magnetic core 1 in a jacket 6 also of high magnetic permeability; a coil 5 wound on the core and a gap 12 between the core and jacket which gap is filled with a plastics material and of which the area is reduced by wear. The jacket is tapered to be pressed into a matching bore in the cylinder wall so the end faces of the jacket 6a and of the core are in the plane of the cylinder wall. Preferably a further coil 4 is wound on the core and a constant area gap 13 is provide whereby the further coil may be connected as a reference in a bridge circuit with the coil 5. The coil 5 may, alternatively, be connected in a resonance circuit of which the resonant frequency provides the measure of wear.
