Magnetic Particle Inspection

EBU

Our MPI benches are available in standard sizes or built to your dimension specifications; with a wide range of magnetising modes and current waveforms, supported by a full range of accessories and ancillary equipment from Baugh and Weedon. Designed and produced in Hereford, UK, the MAGAZON Bench series offers MPI solutions for the testing for components, of all sizes, that require substantial magnetising currents.

Advantages of our EBU Extended Benches include:

All benches can be customised to meet your application needs
Stainless Steel Construction
Footswitch operations
Power pack upgrades available to achieve maximum Amp output
Control Panels built to fit with your inspection process
Suitable to use with water-based and kerosene inks
Inking Systems available
MAGLink2 option: enables PC Control of the MPI bench, enhancing procedural control

Overview

The EBU MAGAZON series of MPI benches offers operators “Extended” choices in the build and design, with a wider range of options that can be added. Our EBU MPI Benches deliver all the key features of the MAGAZON range via three series - EBU3, EBU5 and EBU6F. The EBU3 and EBU5 have 3000 Amp and 5000 Amp power packs respectively. The EBU6F delivers a 6000Amp (RMS) 3 phase, FWDC integral power pack, which can be upgraded to provide a maximum on 7000Amps FWDC.

A wide range of additional features can be fitted to or powered by a MAGAZON EBU series including Encircling Coils, Flux Coils, Special Coils, Remote Magnetising, Swinging Field, Test Piece Supports, Inspection Hoods. The EBU series can accommodate Component Test piece lengths from 1000mm - 3000mm long.
