概述

Olympus is proud to introduce the OmniScan® SX, a flaw detector that benefits from more than 20 years of phased array experience and shares the OmniScan DNA. For improved ease of use, the OmniScan SX features a new streamlined software interface displayed on an 8.4 in. (21.3 cm) touch screen. A single-group and non-modular instrument, the OmniScan SX is easy to operate and cost-effective for less demanding applications.

The OmniScan SX comes in two models: the SX PA and SX UT. The SX PA is a 16:64PR phased array unit, which, like the UT-only SX UT, is equipped with a conventional UT channel for pulse-echo, pitch-catch or TOFD inspection. Compared to the OmniScan MX2, the SX is 33% lighter and 50% smaller, offering an unprecedented level of portability for an OmniScan.

The OmniScan SX touch screen offers a full-screen mode option that maximizes visibility, essentially converting many menu functions into easy touch-screen operations. The intuitive interface provides smooth menu selection, zooming, gate adjustments, cursor movements, and text and value input. These, along with other premium integrated features, including easy-to-follow setup and calibration Wizards, a rapid refresh rate for both the S-scan and A-scan displays, and a fast pulse repetition frequency (PRF), make the OmniScan SX a highly efficient inspection tool.

The OmniScan SX is fully compatible with the extensive portfolio of Olympus scanners, probes and accessories, as well as with its dedicated software companions, NDT SetupBuilder and OmniPC. Combined, the complete family of software and hardware contributes to a streamlined and efficient inspection workflow, from design and setup to acquisition and analysis.

软件特性

The new OmniScan software features enhancements for greater functionality in weld and corrosion markets.

In the effort for continuous improvement, the software interface was simplified and the response time optimized in order to provide the best experience possible for customers.

New features include:

Export C-Scan
New End-View with group merge
Interleave
Analysis attenuation gain
Scrolling layouts for easy interpretation
Improved accessibility with more interactive menus
Optimised main menus and wizards
Onboard compound scan
Curved geometry ray-tracing for longitudinal welds

For applications requiring a multi-probe configuration, the multi-group layouts were improved so that the scanner configuration is reflected in the software interface. The position of the different scans is determined by their distance to the center of the weld, providing an easy-to-understand and appealing layout.

工作流程

The OmniScan Family

Design

NDT SetupBuilder
NDT SetupBuilder design software is an integral part of the Olympus line of automated and semiautomated ultrasonic testing products. NDT supervisors can use NDT SetupBuilder software to simulate the inspection strategy in order to determine the appropriate number of beams and angles. This configuration can be imported into the OmniScan, thereby reducing configuration time and manipulation errors.

Design with NDT SetupBuilder

NDT SetupBuilder is a new PC-based software allowing to create inspection setup and visualize beam simulations.

This software presents multiple features for easy, fast, and comprehensive inspection strategy elaboration that can directly be imported in the OmniScan SX.

Wedge and probe selection can be carried out within the Olympus part database
Instantaneously simulate beams trajectory in the material
Visualize and adjust the part, probe, weld, and beams in different views, such as: side, end, top, or 3D
Represent most commonly inspected materials and parts such as plates, and circumferential or axial welded pipes
Copy and flip existing groups for quick multiple probe configurations

Setup with OmniScan SX

The most efficient way to create a setup is to perform the simulation in NDT SetupBuilder, and imported directly, via SD card or USB key, to the OmniScan. Then, only a few basic operations are required in the instrument, such as setting the gate and range, before acquisition can begin. It is also very easy to create a setup right in the OmniScan, thanks to the following features:

Automatic probe recognition.
Intuitive wizards to guide the user through every step of the setup creation using the interactive help menu.
Weld Overlay and RayTracing simulation.
Group copy option for fast multiple-group configuration.

Acquire with OmniScan SX

Thanks to NDT SetupBuilder and OmniPC campanion software, the OmniScan SX can be dedicated exclusively to calibration and acquisition tasks or, if preferred, can perform all the steps of an inspection, right on its large, user-friendly touch screen.

Calibration

To achieve a code-compliant inspection, the Calibration Wizard ensures that every focal law in every group is the direct equivalent of a single-channel conventional flaw detector. The user is guided step-by-step through the required calibrations like: Velocity, Wedge Delay, Sensitivity, TCG, DAC, AWS, and encoder calibrations. Now, TOFD PCS calibration and lateral wave straightening can be performed automatically.

Acquisition

The OmniScan SX enables easy configuration of inspection parameters for either manual, one-line, or raster encoded scans. The acquisition is displayed in real time through different views and offers the ability to store data on a hot-swappable SD card or USB 2.0 device.

Intelligent layouts for configuring up to 8 groups.
Full-screen mode for better visualization of defects.
Synchronisation and measurements can be processed using different gate combinations.

Data Analysis with OmniPC

OmniPC is a new software program that benefits form the same user interface and analysis and reporting features as the OmniScan with the added flexibility to be run on a personal computer.

With OmniPC, the OmniScan unit can now be used strictly for scanning while analysis is performed simultaneously on a personal computer. This software can also be used in conjunction with extra large screens for increased visibility, and with keyboard shortcuts for faster operations.

OmniPC

Data Analysis with OmniScan SX

Data, reference, and measurement cursors for defect sizing.
Extensive readings database and predefined lists for trigonometry, flaw statistics on axes, volumetric position information, code-based acceptance criteria, corrosion mapping statistics, etc.
Views are linked for interactive analysis and are automatically updated when performing off-line gate repositioning.
Optimized preconfigured layouts for quick and simple length, depth, and height sizing of flaws.

Reporting

The OmniScan SX and OmniPC can both be used to generate reports with an indication table listing up to eight readings, such as amplitude, position, and size of the defects. The report can also be customized with additional readings and comments specific to each indication, and can be saved as an HTML document. RayTracing tools allow the indication positions to be represented on the weld profile. High-resolution images can be inserted along with all relevant inspection parameters.

应用

The Omniscan SX provides Olympus with a new and versatile tool to add to its arsenal of innovative and creative complete market solutions aimed at simplifying your workflow and improving overall productivity.

Phased Array Weld Inspection

The OmniScan PA is at the heart of the manual and semiautomated phased array weld inspection solutions developed by Olympus for the oil and gas industry. These systems can be used for inspection in compliance with ASME, API, and other code criteria, while offering high-speed detection capabilities, and facilitating indication interpretation.

Corrosion Mapping and Composite Inspection

Zero-degree inspection just became even more accessible with the arrival of the OmniScan SX. For corrosion or composite inspection, Olympus offers field-proven solutions for detection of anomalies or wall loss.

Inspection with the portable OmniScan SX

TOFD Weld Inspection

TOFD is an easy and efficient approach for primary detection of weld defects. It is quick, cost-effective and capable of sizing defects present in the volume of the weld, a problematic area for manufacturing defects.

Component Inspection

Using ultrasonic techniques, inspection of components can detect cracks, wall loss, and other damage. With the capacity for both angle and linear zero-degree beams, the OmniScan SX is a very cost-efficient solution for this type of single-group inspection.
