Development and manufacturing of non-
destructive testing units and system
receiver of the piezoelectric element, the upper - transmitter of the
piezoelectric element.
6 . Operation of the device
The basis of flaw detector operation is founded on the ability of
ultrasonic vibrations spread into tested object and reflect from
internal defects and object sides. The received signal is amplified
and
then
converted
into
digital
form
processed
by
the
microprocessor and the graphics and digitally displayed on the
display.
Visualization of signals, display of measurement results, state of the
flaw detector and other information are shown on the LCD. Exterior
of the flaw detector is shown on picture 6.1.
