Contact measurement

  • Measurement error varies depending on operators.
  • 100% inspections cannot be performed.
  • Thickness measurements vary for soft targets.
  • The cycle time cannot be improved.
  • Measurements of narrow locations cannot be performed.

Non-contact measurement

  • No measurement errors attributable to the operator.
  • 100% inspections are possible.
  • No need to worry about the contact pressure.
  • Workpieces are not damaged by the sensor.
  • The cycle time can easily be improved.
  • Measurements of narrow locations are also easy to perform.
