Different components of da Vinci delta ToFD
System

• Probe Cable
• They are a pair of Double Shielded Co-axial
  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.

• Scanner

23
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 .

System

• Offline Analysis Software
• 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 D-Scan
  image which helps him in interpretation and
  analysis.
• Report the defects .
