To maintain product quality it is important that every aspect of an inspection system is monitored regularly. ln particular the performance of an MPI system is dependent on a number of parameters, each of which must be within acceptable procedural limits.

Where magnetizing equipment is fitted with a timer to control shot duration, it must be calibrated on a regular basis, usually to an accuracy within 0.1sec.

Advantages

Is a precision hand-held electronic timer specifically designed to check timer controls fitted to MPI benches.

Has a resolution of 0.02sec and is able to make accurate measurement of the duration of a magnetizing shot in respect of AC, HWDC and FWDC waveforms.

Operates equally for current flow, coil and flux flow magnetizing methods.

Can accommodate dual shots, recording both the first and second shot times and the duration of the rest interval.

Is fully calibrated using equipment traceable to National Standards.

Shot Display… 

Audit ST-1 displays the shot duration for current flow, coil and flux flow with selectable resolutions of either 0.1s or 0.02s. Additionally the magnetizing waveforms are indicated, “A”=AC, “H”=HWDC, “F”=FWDC.

Easy to use… 

Simply press the ON button and the instrument operates at the 0.1s resolution. Press and hold the ON button and it operates at the 0.02s resolution.

Audit ST-1 is held in-line with the magnetizing coil, or a current flow component and the shot performed and displays the shot duration and the waveform code as described.

Then briefly press the ON button to reset the instrument. Audit ST-1 will shut down automatically after 60s of inactivity.

Versatile… 

Audit ST-1 can also measure two successive shot times and the rest interval (up to a maximum of 4 seconds), on dual-shot equipment.

With nondestructive crack detection of magnetizable workpieces, the gauge is mainly used for the measurement of the tangential field strength during the magnetization and for the measurement of the residual field after the demagnetization.

In addition the DEUTROMETER can be used also as a flux density measuring instrument (Tesla meter).

During the magnetic particle crack detection, workpieces are magnetized by means of a current or a field flow.

For a secure indication of cracks a minimum magnetizing field strength must be reached in this case. After termination of the test cycle, the workpiece becomes demagnetized again and environmentally neutral.

In a quick and precise manner, the DEUTROMETER 3873 is capable of checking whether the required strength of the magnetizing field was reached and whether the residual field strength after demagnetization is below a limit.

Doing so, the instrument needs not to be toggled manually: The field detection of the instrument automatically selects the required operating mode.

The menu guidance is executed in comprehensible plain text. The illuminated display and the lettering which fluoresces under UV light permit safe and convenient operation of the instrument inside the darkened testing booth.

The 5100 Series Hall effect portable gaussmeters represent the most recent design from the world leader in magnetic measuring equipment. This new design incorporates the use of digital signal processing technology making it the world’s first hand.held gaussmeter to have a digital signal processor (DSP) on board. F.W Bell’sexclusive Dynamic Probe Connection allows measurements from 0 to 30 kG with a basic accuracy of 1%.

Key features include Auto Zero, Min./Max./Peak Hold, Auto Range and Relative Mode. Both models allow the user to select Gauss or Tesla readings. The Model 5180 also has a selection for readings in Ampere/Meters and features a corrected analog output (:t3V FS)and a USB communications port.

The 5100 Series Hand.Held Gaussmeter’s built.in software eliminates the need for complex calibration procedures. User prompts on the custom formatted LCD allow fast. simple push button operation. All models come equipped with a detachable transverse probe, zero gauss chamber, instruction manual. hard carrying case, and four AA batteries. Axial and other style probes are available as options.

Applications for the 5100 Series range from the most sensitive laboratory environment to the most rugged industrial setting.All instruments are CE compliant.

MAGNETIC FLUX INDICATORS

Surtest magnetic flux indicator strips are widely used to indicate the presence of induced magnetic fields during the magnetic particle inspection method for inspection of ferromagnetic materials. Flux Indicators give evidence of an external field in the air above the magnetised surface and in some circumstances can be used to obtain a semi-qualitative estimate of the tangential field strength H.

Type 1 indicators are typically used for general engineering applications and Type 11 are used for aerospace applications. Both types consist of three laminations measuring SOx 12 mm which are fixed together to form a sandwich structure wh ich is nominally 0.15 mm thick. The outer lamination has 3 interruptions which are parallel to the long side, The width of these interruptions and the material of the outer laminations means that Type 1 indicators respond to a weaker field than Type 11 strips . Both types are protected by a polymeric layer and can be differentiated by the Roman numeral next to the Ely logo.

Flux Indicators have the advantage of being flexible enough so that they can be bent to fit the contours of a workpiece, but robust enough to enable them to be used many t imes. They may also be cut into smaller pieces to allow them to be fixed in recesses and otherwise inaccessible locations on the workpiece.

METHOD OF USE

Attach one flux indicator to a vertical surface of the workpiece under test so that it’s length is at right angles to the direction of the applied current and attach a second at right angles to the first. Magnetise the workpiece by the use of the same electric current wave form as will be used for the inspection and by the same technique.

The magnetisation time will vary according to the self inductance of the workpiece, but should not be less than 3 seconds. While the workpiece is being magnetised apply magnetic particles. It is essential that the application of magnetic particles stops before the end of magnetisation.
