Dual Dryer Scanning System

SSS utilizes the Analyst dual-dryer scanning system to meet the distinctive requirements of ultrasonic inspection on cast iron paper machine dryer rolls. The scanning system records velocity and time flight information, as well as accurate calibration measurements at all times during the roll. In addition the D2S offers the Analyst software for increased flexibility and reporting capabilities.

D2S Capabilities:

  • Automated calibration
  • Reduced zero error (due to wedge construction and wear)
  • Multiplexed, interleaved scanning for the thickness and velocity
  • Fast inspection rates
  • Easily viewable A-scan display
  • Automated reporting
  • Access to TOF data
  • Reliable Trending
  • Flexibility in velocity application
  • View velocity data
  • Reduce noise in data
  • Records thickness data at many different increments (down to 1/4 inch)

We incorporate the Analyst software and data acquisition system for B-scan inspection for a variety of applications from piping to vessels and storage tanks. Automated reporting is applicable for producing data in several scan-plan type categories. By implementing the C1 scanner system, SSS can provide the best tank wall and roof corrosion inspection system available. 

Dual Dryer Scanning System

  • The automated wedge calibration dialog is accessed via menu selection. The dialog guides the user through each step of the calibration using the supplied calibration blocks
  • The more complete calibration eliminates zero errors in both pairs of transducers in any comparable wedge. 
  • The system uses a ultrasonic flaw detector. Available features include a turntable square-wave pulser, time-corrected gain, a high-resolution color screen, echo-to-echo gating, and fast communication rates. The controls are intuitive and easy to use. 
  • The small multiplexer fits into the bottom pouch of the scope case and can be removed when not in use
  • Due to the time-slicing method and speed of the system, the A-scan of the thickness data can be viewed comfortably. For use in monitoring the also-important velocity signal, the velocity A-scan appears as a "ghost image" on the screen
  • The automated data acquisition performed by the Analyst program acquires large amounts of data in a short period of time, reducing data error and loss
  • A graphical, cross-sectional profile of the thickness and other data allows a greatly improved determination of the physical condition of the vessel. If required, a table view of the data is also available
  • Automated reporting of the scan data, vessel physical representation, and all relevant information are sent to the default Windows printer with the simple click of a button. The data can also be printed in table form. This greatly increase the economy of the inspection
  • Automatically converts the TOF data to thickness using the velocity data from the velocity scan
  • Data and reports are available in electronic format
