Multipurpose magnets (also known as curved surface magnets) have magnet "legs" which create a concave or convex bottom designed to fit the contours of a curved machine surface. Curved surface magnets are ideal for applications where the machine surface is not flat, such as on a curved shaft or motor housing. By providing a snug fit between the magnet and the machine surface, a curved surface magnet can help to improve the accuracy of vibration data by reducing the risk of sensor movement or slippage.
It is always recommended that an analyst have booth flat and curved surface magnets in a toolbox to accommodate all types of machine surfaces.
