Dual Electromagnetic Yoke AC/DC 220V,50/60 HZ

Product Details:

Voltage 220v AC SUPPLY
Phase Single Phase
Brand SUPERMAG NDT SYSTEMS

The light weight electromagnetic yoke is the ideal tool for detection of surface or Sub-surface crocks and flows in any ferromagnetic material. No other low cost, portable equipment offers such versatility Magnetic Particle Inspection. Fast and simple to operate, it is widely used with either dry or wet method fluorescent or non-fluorescent Magnetic powders, in the testing of welds, automotive or railroad components, machine ports, steel and grey iron castings, forgings and in plant inspection, maintenance and repair.

Silent Features:

  • Choice of constant level Ac or variable Intensity pulse H.W.D.C. for surface or sub-surface flaw detectability
  • Solid state circuitry for infinitely variable (step less), potention- metric adjustment of DC magnetic field
  • Articulated legs to suit differing component contours, inter pole distance adjustable from 0 to 300 mm.
  • Low power consumption, current draw at 22oV, 1 Phase supply – only 2 amps
  • Extremely strong and intense magnetic field for Superior sensitivity
  • Portable & Light weight – only 3.5 Kgs
  • Can be used for Ac Demagnetization too
  • No risk of sparking or ‘hot spots’ on the job
  • No current flows through the component being tested

Principle of operation:

  • When the yoke is energized, an intense magnetic field is created between the legs. This field can best be described as a multiplicity of invisible lines of magnetic force extending across the gap between the legs. As the yoke is applied to the ferromagnetic component, the magnetic circuit is dosed and the field enters the part making its passage between the legs at and below the surface. A crack across this field cuts the magnetic circuit the crack sides become opposite poles of a magnet and a leakage field occurs in the air above the crack magnetic particles are attracted by this leakage field and indicate the location of the flaw.
  • Preclean inspection area. Spray on cleaner-wipe off with cloth.
  • Place yoke on test piece perpendicular to direction of suspected cracks.
  • Energize yoke. Magnetic field will form in test piece.
  • Apply magnetic powder or prepared bath while yoke is energized.
  • Indications will form immediately.

A.C. Magnetisation:

  • It creates a surface field which only detects surface cracks. Particularly useful for inspecting thick and irregular sections for surface defects such as fatigue cracks. Best results obtained with dry method.

D.C. (Pulsed) Magnetisation:

  • Use of Half wave D.c. magnetization creates pulsing magnetic fields which penetrates the work piece and detects surface and subsurface (slightly) cracks. Pulsing improves particle mobility and sensitivity. Can be used for dry and even wet method

Specifications:

  • AC/HWDC Electromagnetic Yoke
  • Mostly used to test the welds, seams etc
  • Common applications include welding, casting, Forged parts, pipes, and any other random inspections.
  • Suitable for Dry and wet method
  • Input supply 220v, 50 Hz, 1ph (110V model also available)
