Magnetic Particle Inspection

SBU

Designed and produced in Hereford, UK, the MAGAZON Bench series offers MPI solutions for the testing of components, of all sizes, that require substantial magnetising currents.

Our MPI benches are available in standard sizes, but built to your 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.

Advantages of our Standard Benches (SBU) include:

Stainless Steel Construction
Built-in memory for up to 99 sets of test parameters
Current Pre-Selection (CPS) available on all benches
Various coil options including encircling, pancake and split
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 SBU MAGAZON series of MPI benches have a proven track record for reliability and durability, and are in daily use by most of the leading UK Aerospace companies, offering operators 1000 Amps, 2000 Amps or 2500 Amps.

The Magazon SBU MPI Bench is fitted with a stainless steel drain tank, incorporating the fixed position headstock and moveable tailstock. The on-board power pack is mounted underneath, encased in a heavy duty steel cabinet. The cabinet itself is fitted to a steel plinth which means the whole bench can be moved and relocated with a fork lift truck.

Clamping pressure on the Magazine SBU Bench can be adjusted, delivering the protection of delicate components. A “small component fitting” can also be installed, which enables the rotation of smaller components for easy viewing. For heavier test pieces support rollers mounted on the bed bars are available. For the Magazon SBU, a nominal 2500A power pack provides AC, with HWDC (half wave rectified) and single phase, other options are available ; or 3-phase FWDC (full wave rectified) waveforms as options.

Control panels are designed to reflect your application, with buttons being assigned to work in conjunction with your inspection process needs. Digital metering is standard on all units and can be calibrated to display the output current in PEAK, RMS, or 2xMEAN. Two meters are provided, one meter displays HEAD current and the other displays FLUX/COIL current.

The MAGAZON Series is suitable for use with either kerosene or water based magnetic particle inspection inks.
