Configuration and Operation
Regula 7517A is a set of hardware components and software products. The device allows
examining objects using different methods.
Examination starts with magnetic copying (making a magnetogram = magnetic copy) of
the ferromagnetic object surface. The magnetic copying accessories set
(MCAS)
contains
various kinds of magnetic scanners which locally magnetize the object, excite its magnetic
stray fields and copy them to the intermediate flexible magnetic carrier (magnetic tape) without
removing the lacquer–and-paint coating.
The eddy-current scanner
(supplied optionally) is
used for investigating internal stresses in ferromagnetic objects and for examining the surface
of aluminum objects.
The magnetogram is loaded into the
USB device for magneto-optical visualization
(
MOV USB device
) where information about object’s surface layer is scanned. The MOV USB
device combines two functional components: optic-mechanical block and block of electronics.
The optic-mechanical block (OMB)
contains a magneto-optical visualizer which converts
magnetic stray fields of a magnetic copy into an image and a special tape drive mechanism
which moves the magnetic copy relative to the visualizer.
A magnetic copy is loaded into the tape drive where it is automatically detected and
introduced into the tape drive tract. Then it is scanned step-by-step by a sensor designed
on the basis of a magneto-optical crystal. Magneto-optical visualization of magnetograms of
the examined object is based on Faraday magneto-optical effect which occurs in crystalline
films of Bi-containing ferrite garnets.
Light distribution obtained as a result of visualization is received by the sensitive element
of the video camera and is converted into a digital TV signal which is further processed and
examined with the help of PC software.
Step-by-step input of images into a PC allows making automatic panoramic stitching of a
digital image from several sub-shots.
The block of electronics
manages OMB resources (electric drive, inductor, illuminator,
video camera and indicators).
The
PC
operates the MOV USB device via special software. The PC displays newly obtained
and stored examination data which are processed, examined and documented.
Peripherals
(supplied optionally) extend examination possibilities of the device by applying
additional methods and means of investigation.
The device operates together with the following peripherals:
z
USB device for optical input,
