Sonomatic Power Generation Division, employs seasoned professionals with combined decades of experience in advanced turbine/generator NDE. We offer a full range of automated and manual techniques to interrogate the integrity of your turbines and generators; with many of our inspections being used to support engineering remaining life assessments. In addition to our ‘standard’ offerings, such as boresonics, wheel-sonics, blade attachments, generator rotor retaining rings, etc. we also have developed unique, proprietary inspection techniques for specific applications, such as curved axial-entry last stage blade roots on specific OEM blade variants. We also work on all OEM rotors. We work closely with the Electric Power Research Institute (EPRI) by assisting them on various R&D projects specific to turbine & generator NDE; EPRI has also provided independent third-party evaluations on some of our inspection techniques.

Sonomatic brings innovation, value and integrity to the power generation NDE industry. We provide high-end, high-value inspection solutions at reasonable rates. We do so by capitalizing on technology, thoughtful kit design, and efficient work practices. Our motto is ‘Cut Costs, not Quality’.

SonoCAM - Compound Aperture Multiplexing Technique

SonoCAM is a unique, automated phased array technique that combines a pulse-echo phased array, with a distinctive pitch-catch technique for far-superior detection of radial-axial indications on wheel-like components. Ideally suited detection technique for shrunk-on disk-bore/keyways & radial-axial cracking on blade attachments. The technique also improves data collection speeds, boasting up to 50% faster data acquisition by multiplexing than from single-channel scanning.

    Detection Technique:

  • Early detection of flaws is critical, placing greater emphasis on improved flaw detection capabilities. The SonoCAM detection technique is singularly unique in that it has the remarkable ability to exaggerate true reflectors while greatly reducing unwanted background noise.
  • Multiplexing:

  • 'Multiplexing' is in reference to how the data is acquired. Three independent channels are collected, all three channels collect data concurrently, during a single wheel rotation. This is accomplished by multiplexing through each channel rapidly with only one channel transmitting and receiving at any given moment.
