ABSTRACT:
An apparatus for gauging the thickness of coatings on metal products comprises a casing which accommodates a wheel system; a spring actuator with a mechanism for its winding, the actuator being linked to the wheel system so as to enable its rotation; two levers independently balanced in a static state the first of which carries a permanent magnet interacting through its field with a ferromagnetic coating on a product or with the base thereof in case of a nonmagnetic coating, the second of the two levers interacting with the first lever in the event when its force necessary to break away the permanent magnet from the product being gauged is insufficient; two coiled springs, the first of which is connected through one end thereof with the first lever and through the other end with one of the shafts of the wheel system, the second of the two coiled springs being connected through one of its ends with the second lever and through the other end thereof with a spring tensioning control mechanism. Attached to the casing is a magnetic element adapted to attract the permanent magnet after the latter has broken away from the product being gauged. The first lever is returned to its initial position by a reset lever mounted in the casing and connected with the central shaft of the wheel system. Mounted on the central shaft of the wheel system is a pointer for indicating a gauged thickness on a circular scale rigidly secured to the casing. The apparatus is provided with an adjusting shunt mounted in the casing for movement along the permanent magnet and intended for correcting the attractive force of the latter.
