OmniSX MX2 Training 4A PA Calculator Overview

OmniScan SX \ MX2 Training ProgramPhased Array Calculator Overview Chris Magruder V4.1B2T9 Most of the basic theory presented is directly relevant to the OmniScan SX\MX2 and use of the software wizards for common tasks. More PA theory and the supporting mathematical formulas can be found in the below publications available on the Olympus NDT web site. PA calculator hardware and software considerations will be explained with an emphasis on typical 1D probes and wedges designed to be used with the OmniScan SX\MX2 for common applications. Configuring and using phased array with the OmniScan SX\MX2 starts with the population of a calculator (Wizard) for the creation of focal laws. .OmniScan SX \ MX2 Training – Phased Array Calculator Overview This module contains information related to the OmniScan SX\MX2 phased array calculator and the essential parameters required to create groups of focal laws for use. and the instrumentation. (Hardware) Wedge parameters. 4. wedges. (Software) 3 parts hardware and 1 part software that are covered in detail in the next section.OmniScan SX \ MX2 Training – Phased Array Calculator Overview cont. and applications. all hardware parameters must be configured correctly. (Hardware) Focal law beam formation. Phased array calculators differ in functionality and complexity as a result of supporting different types of probes. For proper formation of the focal laws. Probe parameters. The most simple or complex phased array calculators can generally be divided into 4 specific sets of parameters: 1. 2. . the hardware. and the beam formation requested must be within the limits of physics. (Hardware) Material parameters. 3. are entered as part of the setup as well. etc. . wedge databases. Additionally. Use of software wizards. tasks required for the inspection such as weld creation. The OmniScan SX\MX2 group and setup wizards will step the user through each of the 4 relative sections in a logical order. greatly aid in configuring the OmniScan SX\MX2 calculator and preparing the instrument for use while avoiding typos and input errors. probe auto detect. etc.OmniScan SX \ MX2 Training – Phased Array Calculator Overview cont. The speed and difficulty that the phased array calculator can be populated is what separates many instruments on the market in both productivity and ease of use. scanner parameters. probe position. angle. the quantity of A-scans in one or more groups. The delays to the elements occur in nanoseconds and form the beam. and the type of beam formations possible is limited by instrument specifications and software capability and is what separates many systems on the market. Simply a programmable A-scan that allows the beam size.OmniScan SX \ MX2 Training – Phased Array Calculator – Focal Law Definition A focal law is the pattern of time delays applied to pulsing and receiving elements of an array probe in order to steer and focus the resulting sound beam and echo response. and focus to be controlled through software. The speed or PRF. Example of 1 focal law (45 degrees) Software input Transmitter delays (Pulse) Receiver delays (Echo) Resulting A-scan . When used in pulse echo mode the transmitted and received delays are the same and are using the same group of elements.OmniScan SX \ MX2 Training – Phased Array Calculator – Focal Law Definition A simpler explanation is that a focal law is an A-scan. The phasing affect allows multiple focal laws or A-scans that differ in angle and focus to be generated from the same group or different group of elements and summed in a sector scan or linear scan type display. . This is required for complex inspections. or focus options not available on the instrument.OmniScan SX \ MX2 Training – Phased Array Calculator – 1D Array Probes The OmniScan SX\MX2 phased array calculator is populated in normally configured in the part and setup wizards or can be directly manipulated in the focal law menu. 7 . advanced probe support. The OmniScan SX\MX2 also has the ability to import focal laws from a computer based calculator like Tomoview or Setup Builder. The MX2 phased array calculator is limited to 1D linear array types such as circled below. 8 .OmniScan SX \ MX2 Training – Phased Array Calculator – Advanced Probes Complex probes and wedges such as 1.5D and 2D matrix arrays techniques such as pitch-catch require more input parameters and must be generated with a computer based phased array calculator and imported into the OmniScan SX\MX2 on the memory card. 2. Answer: All of the above. Wedge parameters. Material Velocity Beam Formation. 4.OmniScan SX \ MX2 Training – Phased Array Calculator – Advanced Probes Question: What are the essential parameters for the phased array calculator? 1. 3.
