Demagnetisation Equipment

Remove residual magnetism after magnetic particle inspection

Magnaflux demagnetisation units remove any residual magnetism remaining after conducting Magnetic Particle Inspection. Demagnetisation of ferromagnetic parts and materials often requires a requisite to final finishing or to ready an item for its ultimate use. Industrial demagnetising is not an easy task, unless an effective demagnetising system is used. It is especially difficult when the magnetic field must be reduced to a very low level. Compact in sise and ruggedly built, Magnaflux demagnetising equipment offers a fast and efficient method for demagnetising a broad variety of part types and sizes.

Magnaflux Product Description Part Number
ETT Series

The compact demagnetisation tunnels of the ETT series are designed for table-top use.

  • Spool current activated by an ON/OFF switch
  • Saturation depth of the 50 Hs alternating field: approx. 2mm
  • Available in standard and reinforced models/li>
See the Product Data Sheet
ETW Series

Our ETW demagnetisation units with trolley are ideal for demagnetising large, heavy parts which cannot be easily passed through a spool. You place the part onto the trolley and manually push it through the tunnel, where the demagnetisation spools generate a strong magnetic field.

  • Loading aides, distancers and safety grids available on request.
  • Available in standard and reinforced models
See the Product Data Sheet
ETB Series

Our ETB demagnetisation units are primarily used with automated systems. You can place the test part onto the conveyor manually or with the aid of manipulators, e.g. an ejector.

  • Optional lateral guides allow for exact alignment along the entire length of the conveyor.
  • Available in standard and reinforced models
See the Product Data Sheet
SB Series The speed, efficiency and power of our SB units make them ideal for demagnetising after MPI testing. They are designed to fit almost any production or inspection set-up and to withstand hard industrial service, but they are also versatile enough for efficient production applications in tool and machine shops.
  • Broad application - can handle large and small parts
  • Intermittent duty cycle
  • Automatic timing switches
See the Product Data Sheet
S-66 and S-1212

S-66 and S-1212 are compact table-top units designed to fit easily into your existing test/production system. The base of the coil opening can be mounted flush with the work surface, making it quick and easy to insert the test parts.

Both units provide a continuous reversing magnetic field controlled by a conventional on-off switch, ideal for fast, effective, volume demagnetisation of small components on production lines.

  • Built for continuous duty
  • Continuous reversing magnetic field
  • Waterproof and oil-proof (except switch)
  • Table-top installation
007E067 - S-66 (155 x 155 mm opening)
007E106 - S-1212 (310 x 310 mm opening)
