Omniscan MX Ultrasonic Testing (UT)
With hundreds of units being used throughout the world, the OmniScan MX is Olympus’ most successful portable and modular phased array and eddy current array test instrument. The OmniScan family includes the innovative phased array and eddy current array test modules, as well as the conventional eddy current and ultrasound modules, all designed to meet the most demanding nondestructive testing (NDT) requirements. The OmniScan MX offers a high acquisition rate and powerful software features—in a portable, modular instrument—to perform manual and automated inspections efficiently.

GE Phasor (UT)
The Phasor series ultrasonic flaw detector is available in four different models with upgraded features and benefits. Phasor CV is a code-compliant conventional ultrasonic flaw detector that can be UPGRADED to Phasor 16/16 Weld or to the 16/64 Phasor XS. Upgrading to phased array is a quick and easy software upgrade to Phasor 16/16 Weld or Phasor XS. No changes to the base unit hardware are required and utilizing the same simple menu-driven interface as the Phasor CV model, training is minimal. Combined with phased array transducers, both platforms can solve the most demanding inspection applications in less time at an affordable price.
Phasor 16/16 Weld and Phasor XS can switch to conventional UT quickly so that inspectors can use any standard transducer to evaluate detected flaws (locating and sizing) to any specified standard or test instruction.
The Phasor CV/DM combines a phased array imaging device and a conventional flaw detector into one instrument, with a phased array probe, which allows significant increases in confidence in corrosion inspection data.
Physical Acoustics Corporation (PAC), Highway Sensor II Acoustic Emission (AE)
The instrumentation required to detect discrete acoustic emission is sophisticated. A straightforward AE instrument hardware design includes a transducer, preamplifier, band pass filter, amplifier, and several digital signal processors. The exact way in which signals are gated, filtered, and interpreted adds complexity because of background noise present during the measurement. With background noise removed by the signal processors, the next problem is correlating the AE signal level and the status of the material and structure that is being tested.
The AE instruments use proprietary software to perform extensive signal analysis after the hardware amplification and processing. The combined results of the acoustic emission instrument hardware and software is a complete characterization of the suspect AE (signal) and thus, a reliable characterization of the source phenomenon of the acoustic emission, be it caused by a crack, leak, friction, etc.
The meandering winding magnetometer (MWM) is an eddy current sensor that is flexible, lightweight, and can be fabricated and tailored in a variety of shapes and sizes to fit a wide range of applications. MWM-Arrays can be integrated into scanners to produce images of cracks, hidden corrosion damage, and stress distributions, or can be incorporated into structures and components to provide early warning of internal degradation, and to monitor stress. Scanning MWM-Arrays were developed in response to a Navy requirement for nondestructive evaluation (NDE) techniques to assess the state of structural fatigue in naval aircraft. The sensors and arrays are able to inspect aircraft engine blades and fretting regions of engine disks where fatigue crack detection by conventional NDE techniques has been unreliable.
The Nortec 2000D+ offers a frequency range of 50 Hz to 12 MHz for applications ranging from detection of cracks in tubes or structures to the discovery of minute flaws in aircraft materials. Single or dual frequency operation, easy-to-use digital conductivity, and rotating scanner support make the flaw detector ideal for numerous aerospace NDT applications.
Customer-interchangeable displays offer excellent visibility in any lighting condition. A Video Graphics Array (VGA) output drives a heads up display for inspection where conditions may be cramped or a large desktop monitor or projector for classroom training.
At less than 4 lbs (1.8 Kg), the rugged Foreign Object Debris (FOD) free case will survive harsh field and production environments. An adjustable tilt bail and antislip bumper allow the unit to be placed on just about any surface.
The Nortec 2000D+ incorporates unique PowerLink™ software, which provides automatic probe recognition and documentation. The instrument can be set-up by recalling the program stored in the PowerLink™ chip, providing integrity, and repeatability of inspection results.
As many as 120 programs can be stored and recalled later. Date and time are recorded with each setup and are easily identified with alphanumeric values up to 29 characters long. Twenty memory locations are available to store eddy current.
Forward Looking Infrared
Residential, commercial, and industrial buildings can all suffer from a wide variety of problems associated with their design, construction, equipment failures, and external forces. These problems can result in large expenditures to fix things that have gone unnoticed for too long. Even when symptoms are evident, it's often difficult to find the source of the problem. This can result in secondary damage that poses risks to occupants, or leads to destruction of the building. FLIR B-Series infrared cameras are a noninvasive way for inspectors and contractors to find problems and initiate repairs quickly.
Infrared (IR) thermography with FLIR cameras is a noncontact method for detecting the difference in temperature between a problem area and its surroundings. Depending on the underlying cause, the problem area may be warmer or colder than its surroundings. This temperature difference is clearly visible in the camera's image display. A trained operator can immediately hone in on the source of the problem and what's causing it – without having to first tear into walls or disassemble equipment.
MIRA (Concrete phased array UT)
The Malå Imaging Radar Array (MIRA) system consists of several separate transmitter and receiver antennas combined into one single antenna array unit. In operation, the antenna array is tracked and positioned by a robotic (self-tracking) total station or a Real Time Kinematic Global Positioning System (RTK GPS) for precise positioning. This give several parallel profiles exactly positioned at the same time, resulting in a seamless 3D picture of the subsurface, with a high-resolution of subsurface features both in horizontal and vertical direction.
The MIRA systems represent a completely reworked, revolutionary new generation of ground penetrating radar (GPR) equipment, patents pending. At this time, MIRA systems are not available in the United States due to Federal Communications Commission regulations. The systems are currently sold directly from the manufacturer’s head office in Malå, Sweden.
The MALÅ GPR CX Concrete Imaging System allows you to perform ground penetrating radar scans of a concrete structure simply and safely and present data clearly for real-time and in-the-box 3D data acquisition, display, and analysis.
The MALÅ GPR CX System provides accurate inspection of concrete structure such as floors, walls, slabs, and bridge decks for the detection of metallic and nonmetallic objects and features (i.e. rebar, post tension cables, metallic/nonmetallic conduits and pipes, voids, and for the measurement of slab thickness).
The software for the MALÅ GPR CX System includes three different measurement modes; 2D, 3D Grid and Object Mapper projects, which makes it the most flexible and comprehensive system on the market.
The extremely user-friendly software with its simple interface may be operated by either the popular push-and-turn knob, or in a fully remote mode using buttons on the antenna.
