Software - Masterscan


The SDI MasterScan/WinScan® suite is one of the most powerful motion control and acquisition packages available. Designed from the ground up as a true Windows® application it has significant operational advantages over the competition. It is continually enhanced through feedback from our large international user base and our own test lab subsidiary.


The well structured modular software has evolved by incorporating customer’s motion control and acquisition requests into the standard product. With a user base of over 100 systems, incorporating the suggestions of technicians who spend all their time operating our equipment has resulted in the most versatile, user friendly, package in the industry.

Targeted primarily at high volume test lab users, the principal operational criteria are ease of use and fastest possible inspection times.

In addition to numerous custom systems, the SDI standard product range of over 14 systems types are employed in three main industry areas:


SDI’s range of high performance complex 3D scanners is able to perform simultaneous through transmission and pulse echo inspection on complex 3D composite parts. Advanced features include:

  • Automatic teaching of component scan plans.
  • Automatic normalization and water path adjustment.
  • Import/Export of scan plans to CAD.
  • Nested scan plans where multiple parts in different locations can be tested in the same sequence.
  • Automatic identification of defects with the cluster analysis feature.


SDI’s range of heavy duty plate and bar and billet inspection systems are designed for operation in harsh environments using sealed touch screen controls an air conditioned control enclosures.

Typical examples are bar systems with multitransducer bar followers performing multi zone inspection on 16000# round billets and plate inspection systems with up to 32 simultaneous data acquisition channels.


The SDI MasterScan is a Microsoft Windows® based high-speed, multi-axis, coordinated motion control package targeted at large scale production inspection and test lab applications. Developed by SDI for its extensive range of ultrasonic systems, MasterScan is installed on products ranging from small lab scanners to precision tanks and through transmission gantries.

MasterScan is used with a range of ultra low noise dc servo products designed and manufactured by SDI specifically for demanding ultrasonic applications. The MasterScan control package, working with WinScan acquisition and analysis, acquires data from up to 8 channels with both through transmission and pulse echo curve following capability.

For curved scans the scan index increment is measured along the surface of the part being tested. The package provides such features as ‘stop on defect’, ‘return to defect’, ‘chain scanning’ and ‘scan scripting’. The front end user interface, configured to match the application, ranges from a simple touch screen controller for bar scanners, to full featured controls for 3D through transmission contour following.

Scan profiles are taught using the front surface echo. 

SDI systems are designed to function with a wide range of third party flaw detectors. Instrument set-ups can be stored with the scan plan for a number of Olympus and GE instruments.

For scripted scans, with multiple inspection sequences, a series of scans with different instrument set-ups are performed sequentially without operator intervention. Each scan produces a separate data file with automatic file name generation.

When used with the SDI-2800 programmable flaw detector, instrument parameters can be changed ‘on-the-fly’ as part of the scan plan. e.g. a gate can be set up to follow the back wall of a part with rapidly changing thickness, or follow a bond line under similar conditions.


SDI’s WinScan® is one of the most versatile ultrasonic acquisition and analysis packages available for production inspection and defect evaluation. Approved and used by all major aerospace prime contractors, the extensive features, intuitive operation and flexible data input alternatives have made it a popular choice for analysing and printing data acquired from a variety of sources.

In standard configuration WinScan® captures up to eight channels of 12 bit peak detected data in C-scan format. Defect evaluation, using the MiniScan feature, provides B-scan and full waveform capture features. The number of palette levels and palette colors are operator selectable.

Data can be displayed as percent of full scale, in dB or scaled for use with log amplifiers. Bipolar data display is provided for Eddy Current applications. Displayed data can be compressed, zoomed and panned. Analysis features include line cursor measurement, image enhancement, region of interest (ROI) histograms, signal to noise ratio measurement and cluster analysis.

During analysis indications can be annotated with a marker. The marker position and the comments are stored with the data file. If the part is still in the scanner, the transducer can be sent to a defect indication for further evaluation with the transducer following the part contour.

If defect evaluation is required while the test is in progress, it is possible to pause the acquisition while the transducer is jogged over an indication for evaluation. When completed the acquisition can continue from the original pause location or from the current position.

The WinScan® package offers extensive reporting and printing capabilities. The high quality illustrated documents produced can be printed on any printer or plotter with a Windows® driver. WinScan® also has the capability of plotting selected areas of the scan at any even integer scale from 1:8 to 8:1 allowing test results to be overlaid on the component being inspected.

WinScan® is fully compatible with the Windows® local area network. This means that adding a second PC with access to shared disks and peripherals over the network can enhance the system performance.

This would be advantageous when carrying out high volumes of data analysis and report generation while scanning other components. The real time analysis feature allows data from a component being inspected to be analyzed before the scan is completed.


Bubbler Systems

Ultrasonic Bubbler Systems

SDI manufactures a range of bubbler or irrigated transducer systems. This type of system is usually product specific where full immersion is not possible and the laminar flow squirters with coupling distances of over 6 inches are not necessary. These relatively low flow volume systems systems including those designed to test compressed gas cylinders, automotive components, and metalic stripand the SDI range of portable scanners.


This specification is for an automatic, multi channel, high-resolution ultrasonic test system for heavy cylinder inspection. The SDI-5280 rotator system with irrigated transducer test head can be installed in-line with automatic load and unload stations. Sorting chutes and paint markers are also available.

The ultrasonic instrumentation is a ruggedized three channel SDI-2480-3 Modular Ultrasonic Flaw Detector. It is designed to achieve the accuracy and resolution required at high throughput speeds in a harsh operating environment.

The system will test product with diameters ranging from 6 in (150mm) to 24 in (600 mm). This specification describes the maximum standard system size which will accommodate lengths up to 20ft. The actual system size and part length is determined by customer requirements.

SDI-5280 Overview

The system consists of floor mounted sump supporting a 20ft (8m) long SDI-1332 medium duty rotator. The transducers are mounted in-line in a high flow irrigated housing which rides in contact with the bar.

This type of housing is used extensively on the SDI compressed gas cylinder inspection systems which are used with very heavy duty cycles on a variety of rough surfaces. It provides coupling equivalent to an immersion system as a water filled chamber is maintained between the transducer and the part.

The test head is mounted on a bridge equipped with a bar follower assembly. There are a number of different contoured shoes which can be rapidly changed by the operator to accommodate different bar diameters. Each shoe size will test several different bar diameters.

The bar to be tested is automatically loaded onto the rollers and the transducer/follower assembly lowered onto it. As the bar is rotated, the transducer assembly traverses the entire length of the bar. All test parameters, including rotator speed, helix pitch etc are controlled by the SDI-1830-UTB system controller.

The time to test a bar is dependent on the test standard defect size and determined by the bar diameter. To reduce inspection time the testing is performed bi-directionally. The test bridge moves off the bar into a shielded housing at the end of each scan.

It remains protected until the next bar is loaded onto the rotator then it emerges and travels the opposite direction down the length of the next bar and into housing the other end. The sequence is repeated for each bar. The principal components are:

  • Test Station
  • Material Transport Modules
  • Auxiliary Modules

The modular design allows rapid reconfiguration of the system to accommodate different lengths and diameters of bar. The detailed description of the modules is given below.

Test Station

The test station is the main operating station of the system and contains the sump, rotator, bridge and system controls. In the majority of systems, the instrumentation and system controls are housed at the end of the test station, as this is where the operator will usually be located. The test station frame is fabricated from welded steel and finished with epoxy paint.

The overall length is 24ft. and the depth 3ft. The transport roller centerline height is 39in. The SDI-1332 rotator will function in either direction with continuously variable speed. The maximum speed is 40 surface inches per sec.

Material Transport Modules

The material transport modules are two different modules for handling the material as it progresses through the test system: Loading Station and Off Loader Station. All transport modules are manufactured from heavy duty welded and bolted steel construction. Adjustable leveling feet are used on each station to allow precise alignment.

The rollers used are manufactured from high-density polyurethane or neoprene as determined by the application. The frames are finished with epoxy paint.


Product is loaded onto a feed ramp, which can be built to any length to allow for accumulation of product. A pneumatically operated part selector separates a single bar and positions it on the rotator rollers. The bar then rotates and the test head moves at a speed determined by the required helix index.


Air actuated off-loaders are provided with various numbers of lifting arms to suit different length bars. Defective parts can be directed to a reject stack. Automatic defect marking is provided.


A number of auxiliary modules are provided for improving the inspection efficiency.


Automatic defect markers are available for indelibly marking the product downstream of the test station. Both paint jet and felt tip markers are available.


A computer-based defect logging package is available for producing a tabular output of defect location and material length.


A re-circulation pump and filter system ensures water quality is maintained under normal working conditions. Optional temperature control and de-airation units can be provided.


The instrumentation used will be the SDI-2480-3 three channel flaw detector. This high speed, high-resolution instrument is designed for industrial on-line applications where features such as the interface gate synchronization eliminate variations due to surface conditions and bar flutter. The unit has eight sequenced channels each consisting of a pulser/receiver module. Each channel will accommodate two gate modules with rear panel outputs and front panel LED displays indicating the gate condition. For each channel a flaw gate LED will be illuminated if an echo appears in the gate above the preset thresholds. Thickness modules are available if required.


All system functions will be controlled and monitored by the SDI-1830-UTB system control module. This is an integrated suite of software modules running on a rack mount industrial P.C. with an optional touch screen display. There are four main functions:-1)Instrument set-up and display, 2) System control, 3) Operator input, and 4) Data logging. The screens can be custom designed for particular applications. Typical screens for each of these functions are shown below. These could be reconfigured as required.


This screen allows each instrument channel to be set up and directs the video and gate outputs from the selected channel to the display scope. At any time the operator can view the A-scan display of any channel by touching that channel number on the screen. All set-ups can be stored and recalled with a file name. Other functions controlled include:

Instrument set-up; gain, gate position and gate threshold.

Instrument response monitoring -either the alarm condition, the signal amplitude or the time of flight.

Multi-channel sequencing to prevent cross talk by sequencing pulsing, gate position and gate width on each pulse.

Transducer manipulation where motorized transducer positioners are used the positions of each transducer for each material, type and size can be stored as part of the test parameter set-up. (option)


This is the main screen for controlling system configuration parameters and defect location markers. The inspection helix pitch is controlled as determined by the required defect detection level. The system controller controls the drive speed and helix angle of the system together with the sequenced actions of the load station, off load station and sorter. This module receives input from various sensors on the system and instrumentation and determines a sequence of events based on these inputs. The precise sensor input is determined by the type of test being performed and the options installed. Custom inputs can be accommodated for special functions.

For the variable input levels, both digital and analog, internal comparator logic allows the operator to set high and low thresholds for the quantity being measured. When these thresholds are exceeded the required response can be programmed. An example of this device would be the marking of regions where different types of defect occur.

Other parameters monitored are rotational speed and linear velocity of the bridge. Part diameter can be entered manually or automatically measured.

There are a wide range of programmable controller responses, examples of these are 1) delayed response, for the action of down stream devices, such as paint markers or sorting stations, and 2) defect indication suppression. This is required at or near the end of a part.

It also provides direct operator jog control allowing the system to be reversed to investigate defect indications.


This screen allows the operator to input the details of the product being tested.


This screen shows the condition of the system alarms. All alarm outputs will be continually monitored using this SDI-1910 Posilog PC data logging package. When an alarm condition occurs the Posilog will record the channel number, alarm type and encoder counter reading. These values will be displayed on the screen and stored to disk. In addition, an optional paint marker will indicate the occurrence of a defect on the side of the bar. The defect log files will be accessible in read only mode from any other PC networked with the host.
