    DEVELOPMENTS OF THE INSTITUTE :: Universal magnetic thickness gage

    Application

    The Mag–6 is intended for thickness measurement of ferromagnetic metal under a layer of a non-magnetic coating or corrosion as well as of the layer of coating or corrosion. It can also be applied to measure the thickness of ferromagnetic sheets and products without coatings and to measure the protective non-ferromagnetic coatings on a ferromagnetic basis.

    Operational principle

    The work of the device is based on the measurement of the normal component of induction of a secondary field in two points, where its dependence on the thickness of non-magnetic coating has various behaviors. Such dependence is provided by the specially created source of a primary (magnetizing) field on the basis of constant high-coercitivity magnets.


     

    A: non-magnetic layer (rust, oil stain, dust or micro-defect of metal surface)
    B: magnetic substrate ( steel, etc)
    1: ball probe
    2: permanent magnet
    3: material under testing
    4: measuring coil or Mall’s transducer
    5: measuring unit

    Local volume of material is magnetized by permanent magnet via ball made of steel when the ball is contacting the material. After that, the probe is separated from the material and the measuring coil interacts with the magnetic field created by magnet in material. Interaction signal depends on the thickness of non-magnetic layer on the surface of material

    Construction

    The Mag-6 consists of the transducers and the electronic block. The transducer includes the magnetizing system and the measuring elements, and does not contain special devices for detachment from the products. The electronic block has the built-in program for processing of the measured results, which transforms the received values of induction into the absolute ones of the thickness of non-magnetic coating and ferromagnetic basis according to the given algorithm. The measurement results are indicated on the service panel.


     

    Specifications

     

    It is possible to expend the range of the measured thickness by introduction of the additional mechanism of the transducer detachment from the product.
