| Summary: | An assessment is made of the influence of the parameters of a controlled part by the
magnetic method of non-destructive testing on the gradient of the magnetic field
strength of the measuring transducer. A simplified design of a pulsed gradiometric
transducer is presented, and its parameters for conducting experiments are
indicated. A mathematical model for calculating the output signal of a gradiometer
fluxgate used to obtain output data is considered. The dependences of the magnetic
field intensity gradient on the distance between the sensor and the plane of the
controlled part, on the coercive force and thickness of the hardened layer, as well
as on the thickness of the controlled part are studied. Conclusions are drawn based
of the experiment performed. |
