Product Overview
Yoke Type Magnetic Particle Inspection (MPI) Equipment / Crack Detector Machines
Yoke Type Magnetic Particle Inspection (MPI) Equipment, also known as Yoke Type Crack Detector Machines, are portable Non-Destructive Testing (NDT) devices used to detect surface and near-surface discontinuities in ferromagnetic materials such as iron, steel, and nickel alloys.
These compact and efficient machines use a magnetic yoke to generate a magnetic field over a localized area of the test component. When used with magnetic particles, they can easily reveal cracks, seams, laps, and other flaws without damaging the part.
MAYURESH ENGINEERS is a leading manufacturer of Yoke Type MPI Machines in India, offering robust, reliable, and user-friendly inspection systems for field and workshop applications.
Working Principle of Yoke Type MPI Machines
The magnetic yoke consists of two poles connected by an electromagnetic coil. When an electric current (AC or DC) flows through the coil, a magnetic field is generated between the yoke poles.
The component to be tested is placed between these poles, and the magnetic particles are applied to its surface. If a discontinuity exists, magnetic flux leaks out at that point, and the particles accumulate to indicate the location and size of the flaw.
AC yokes are commonly used for detecting surface cracks, while DC yokes can detect both surface and slightly subsurface defects. This makes Yoke Type MPI Machines highly versatile and effective for various inspection needs.
