Portable Bench Unit - PBU-350

"A perfect portable MPI solution"

The PBU 350 Portable Magnetic Particle Inspection (MPI) Bench Unit offers great MPI performance teamed with the outstanding quality that Baugh & Weedon is known for. With a long rich history of designing and building MPI benches of all sizes, it is fitting that we have added the portable bench option to our range.

As well as the key features, there are various aspects of the PBU design that set it apart in the marketplace including the ability to add an inking system to the unit offering maximum flexibility to the inspector.

The PBU uses a gas spring to provide the clamping pressure on the headstock that ensures optimum electrical contact with the component under test. We have also developed the coil to offer bi-directional clamping allowing the coil to be manually rotated at 90o for maximum inspection flexibility.

MPI Bench - MAGAZON EBU

Baugh & Weedon Ltd is a trusted supplier of MPI equipment to the NDT industry.

The MAGAZON series construction is based on a heavy-duty framework fitted with a stainless steel drain tank.
The frame design usually allows the power pack to be mounted integrally. Alternatively, the power pack can be
housed in a separate cabinet.
Bed bars which support a fixed position headstock and movable tailstock, are mounted in the tank. For ease of
movement the tailstock has sintered phosphor bronze bearings and is fitted with a simple lock. The head and
tailstocks are equipped with test piece supports and easily replaceable copper mesh contact pads.
Pneumatic clamping prior to magnetising is operated by a footswitch.
On the Magazon SBU, the clamping pressure can be reduced, which affords protection to delicate
components. A small piece device can also be fitted, which provides rotation of the component for easy
viewing. For heavier testpieces support rollers mounted on the bed bars are available.

Instrument controls and digital ammeters are on an eye-level console located above the headstock. 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, each with independent control. One meter displays HEAD current, and the
other displays FLUX/COIL current.
Selection of magnetising mode, current waveform and shot time is by rotary switches. Indicator lamps show
power ON and READY, while illuminated push-buttons allow initiation of magnetising and demagnetising
cycles. Each console is populated in accordance with the options provided on the particular unit and a typical
example is illustrated,
The MAGAZON EBU and SBU Series has a universal,
microprocessor based, electronic system which allows many
additional features to be incorporated. These include:
+ Current pre-selection. The required current level once selected is
automatically achieved when the magnetising “shot” is initiated.
+ Built-in memory. An integral memory will store up to 99 sets of
data including all test parameters for each component. This feature
is extremely useful when testpiece batches are small, and frequent
changes are needed.

For the Magazon EBU, nominal 3000A or 5000A AC power packs are
standard, though alternative options are available subject to technical
appraisal.
The provision of HWDC (half wave rectified) or FWDC (full wave rectified)
waveforms can also be accommodated.
On standard models infinitely variable current control is achieved using
thyristors resulting in a complex current waveform. However, where a
sinusoidal waveform is required for compliance with some test specifications,
the option of variable transformer control is available for both the Magazon
SBU and EBU.

Magnetic Particle Inspection Bench - MAGAZON SBU SERIES

MAGAZON Series bench to provide increased inspection capacity

Magazon SBU, a nominal 2500 A power pack provides AC, withHWDC (half wave rectified) and single phase, or 3-phase FWDC (full wave rectified) waveforms as options

The MAGAZON EBU and SBU Series has a universal,
microprocessor based, electronic system which allows many
additional features to be incorporated. These include:
+ Current pre-selection. The required current level once selected is
automatically achieved when the magnetising “shot” is initiated.
+ Built-in memory. An integral memory will store up to 99 sets of
data including all test parameters for each component. This feature
is extremely useful when testpiece batches are small, and frequent
changes are needed.

The SBU version of the Magazon Series is ideal for smaller test pieces and components up to 1200mm long and requiring lower magnetising currents. All Baugh & Weedon MPI Benches are made to fit your application specifically.

CONSTRUCTION
The Magazon SBU MPI Bench is fitted with a stainless steel drain tank incorporating bed bars to support
the fixed position, pneumatically operated headstock and moveable tailstock. The Power Pack is integrally
mounted underneath the tank in a heavy-duty steel cabinet. This is mounted on a steel plinth, hence the
whole bench can be easily moved with a fork lift truck
When testing small delicate components the optional addition of spring pressure can be included to provide
protection against damage. A small piece device can also be fitted, which allows rotation of the component
for easy viewing. The head and tailstock are fitted with V-block supports, but for heavier test pieces support
rollers mounted on the bed bars are available.
