made of aluminum alloys (silumin bodies of the blocks of cylinders
and reducers, manufactory’s aluminum plates, duraluminium bodies)
and extends the functionality of the equipment when examining weak
signals in the supercial layers of ferromagnetic items, e.g. – residual
(accumulated) tension.

Structure and Operation of the Device
The device consists of 2 basic structural elements (Fig. 2):
the controller and the scanner. Scanners are specialized according
to the type of the examined material. Thus, Al-scanner is intended
for electro-conductive non-ferromagnetic materials and Fe-scanner
for ferromagnetic materials. Two ACC are the power supply source
of the device controller. These batteries are charged by a subsidiary
charging unit. Device function control is carried out in the composition
of Regula 7505M using test-objects №1 and №2.
Magnetographing with the use of the device consists in the successive
execution of a number of operations. Demagnetize, place and x
the magnetic tape on the examined surface beforehand. Connect
the scanner corresponding to the examined material type to the device
controller. Switch on power supply of the device controller and move
the scanner is moved along the examined surface.
The device controller creates and sends voltage impulses with set
parameters to the scanner. Pulse current, which ows in the scanner
conductor, creates around the scanner the alternating magnetic
eld, which induces eddy currents in the conductive material of
the object. The eddy currents trajectories and connected with them
magnetic stray elds reect the lines of electric resistance specied
by the form, sizes and positioning of defects in the examined item.
The obtained magnetogs of the object (VIN) stray elds are visualized
by Regula 7505M under its OM. The obtained images are processed
and analyzed for the following expert appraisal.

The device controller (Fig. 3) is produced in a metal body (pos. 1).
The controller side slab has a socket for connecting the scanner
(pos. 2), and ACC charging device (pos. 6).Its bottom panel provides
access to the ACC compartment. The control button (pos. 3) and state
indicators of the controller and ACC charge (pos. 4) are located on
the front panel of the controller body.

During the operation the device controller creates and sends
voltage impulses with set parameters to the scanner. These parameters
correspond to the type of the connected scanner and the selected
operating mode. Moreover, the controller carries out self-diagnostic,
controls ACC charge and provides its additional charge (if the ACC
charging device is connected).
After the scanner socket (pos. 2) is connected and power supply
of the controller device is activated with the button (pos. 3),
the indicators may have the following states:
Only the green indicator glows – controller state and ACC
charge are normal; the scanner is activated – it receives
voltage impulses necessary for magnetographing;
The green indicator glows and the red indicator blinks
impulsively – ACC charge is needed;
The green indicator blinks impulsively – the current
operating mode. The indicator blinks one time when
switching on the controller and changing its operating
modes. The numbers of ashes correspond to the power
level of Fe-scanner (see paragraph 2.3 for the power levels);
None of LEDs glows – ACCs are absent or are fully
discharged, the device controller malfunction;
The controller switches off automatically one minute after
its activation to save energy and protect the scanner from
overheating.
To save energy and protect the scanner from overheating, the
controller is switched off automatically in a minute after activation.
When the ACC charging device is connected to the controller device
(socket – pos. 6) and its power supply is connected to the mains
220V, the yellow indicator (pos. 4) may glow. The glowing means
the presence of external power supply (=24V) at the controller
input, which provides additional ACC charge of the ACC including
the ACC charge during the device operation process.
The access to ACC for their charge and replacement is carried
out by unscrewing 4 screws and removing the cover of the ACC cells
(pos. 5).
External view of AL-scanner is given in Fig. 4.
The Al-scanner is intended for examination of non-ferromagnetic
materials. The scanner is shown in Fig. 4. It is designed in a plastic
body (pos. 1). The eddy-current inductor (pos. 2) is inserted into
the groove in the lower part of the scanner and xed with screws
(pos. 3) on the pads.

The system of conductor tension is designed in the form of a dielectric
cushion (pos. 4). An arrow (pos. 5) with a symbol indicating the type of
examined material shows the direction of magnetic tape demagnetization
(preliminary) and examined object scanning. The scanner is connected
to the controller via the cable (pos. 6) connector.
During operation the ECMD forms and sends voltage impulses with
specied parameters to the scanner inductor. To carry out magnetic
copying, x a demagnetized magnetic tape on the examined surface.
And then move the scanner in the direction indicated by the arrow
(pos. 5) along the examined area.
When carrying out magnetic copying of a relief surface, the elastic
pressing cushion (pos. 4) deforms the inductor (pos. 2) in accordance
with the current surface relief.
