HARDWARE
Modsonic’s ‘ da Vinci delta ‘ is
one of the variants of ‘ da
Vinci ‘ Series of high end
Imaging Ultrasonic Flaw
Detectors . Following are the
salient hardware features
pertaining to ToFD application :
Our ‘ da Vinci ‘ Series Ultrasonic Flaw
Detectors are named after Italian
painter and inventor Leonardo da
Vinci described by some as the most
diversely talented man ever to have
lived on earth .A truly Superhuman.

*Display : Real Time RF A-Scan data with
auto-scrolling ToFD D-Scan image are
displayed on the screen during data
collection. ( show video clipping of Autoscrolling ToFD D-Scan )
*No. of Channels : One Transmitter ( Tx)
and one Receiver ( Rx)
*Position Encoding : It can be Freerun (
Unencoded ) or with Encoder .It is single axis
, Bi-directional.
*Data Collection Step : It is Selected Length
divided by 1000 . Eg with 1 meter Selected
Length Data Collection Step is 1mm

Hardware
*Data Collection Length : Can be
selected from 500 mm to 10,000 mm.
* Averaging : Averaging is internally
controlled based on Selected
Range/PRF and Test Length.
* Data Storage : Collected data can be
stored on USB drive ( Pen Drive ) . Each
data is stored in separate file with Auto
Incrementing file name. USB drive of 8
GB is supported . Total of about 16 Kms
of Weld length can be stored on 8 GB
USB drive.

Probe Cable
They are a pair of Double Shielded Coaxial cables of 2 meter length each
with Lemo 00 connector on one side
and BNC on the other . They connect
ToFD probes to the main unit . As
ToFD technique requires higher gain
to be adjusted on the machine the
noise level can increase due to
electro-magnetic interference ( EMI
) . The double –shielding provided on
the cable helps keep the noise level
due to EMI at low level.

‘ da Vinci delta ‘ ToFD System
ToFD Probes
They are highly damped, broad-band
probes which produce WIDE BEAM
required for ToFD inspection.
One probe is connected to the
Transmitter connector ( Tx) and other
to the Receiver connector ( Rx) on the
top of ‘ da Vinci delta ‘

Wedges
They are Stainless Steel or Brass
wedges with Irrigation channels
ToFD probes are to be screwed into the
wedges which in turn are mounted
on the Scanner ( using the gimbals
they are pivoted on the forks of the
scanner ) provided .

Scanner
Different components of
‘ da Vinci delta ‘ ToFD System
Encoder
It is Single Axis , Bi-directional
Encoder. It is attached with the
Scanner using a bracket .
When properly calibrated it gives
surface distance of probe in
mm from the reference point .
The input available from the
encoder gives information on
location of the defect and also
its length .

Offline Analysis Software
The software supplied with ‘ da
Vinci delta ‘ ToFD System is
called AsalView.
It enables the user perform the
following functions :

Functions of ‘ AsalView ‘
*Opens the files containing ToFD
Data which are then displayed
as D-Scan image with
corresponding A-Scan.
*The user then using the rich tools
provided in AsalView can
electronically enhance the DScan image which helps him in
interpretation and analysis.
*Report the defects .
