Ultrasonic Testing (UT) Systems

MISTRAS UT (ultrasonic testing) products range from portable hand-held single channel to industrial production testing systems using phased-array probes and multi-axis.

MISTRAS Group, through its Products and Systems Division, offers a full line of Ultrasonic (UT) products and inspection systems designed to fit the needs of any testing market. From immersion systems and large-scale scanners, to single or multi channel systems; UT boards and software, to system scanners and accessories, MISTRAS’ UT solutions fuse the necessary engineering, design, and production capabilities to create a dynamic product line. Those comprehensive offerings embody our mission to be a one-source provider of asset protection solutions. UT testing measures the propagation of mechanical vibrations (ultrasonic waves) through a material to examine properties, detect discontinuities, measure thickness, determine elasticity, and more. MISTRAS designs and manufactures all major components of our UT solutions in-house. Therefore, we maintain total control over products specifications, pricing, system performance, and customer satisfaction. It also allows us to offer certain custom, made-to-order systems. No matter your industry, testing market, or need, MISTRAS has the UT testing solution. In many cases existing production systems can be upgraded using a MISTRAS UT system upgrade package, saving the high cost of mechanicals which may have many years of serviceable life remaining. MISTRAS standard products for UT include:

Pocket UT System:

The Innovative Pocket UT is a battery-operated, hand-held, stand-alone, full C-Scan data acquisition system. Its portability and ease of use, coupled with its full A, B and C-Scan capability and optional TOFD capabilities, make the Pocket UT® System ideal for on-site inspection applications. It quickly assesses the presence, depth, shape and orientation of cracks, flaws, corrosion/erosion, delamination, and internal anomalies in a variety of structures, materials and surfaces. The Pocket UT® can operate as a conventional thickness meter (for spot readings), a basic flaw detector with RF display and alarm gates, or in either active B-Scan or full C-Scan modes. The system has a bright, back-lit LCD colour touchscreen, and an easy-to-use keypad for fast entry of common commands and data. Weighing approximately 2 lbs. (.9 kg), the Pocket UT® uses the Windows-CE™ operating system and integrates all ultrasonic components together in a rugged, rubber-encased enclosure. With a user-replaceable and rechargeable battery pack, the system can also operate via the included 100-240 Volt AC/DC adapter/charger.

Tablet UT – Ultrasonic Imaging and Analysis System

The Tablet UT™ is a high-speed data acquisition and imaging system that provides full A-, B-, and C-Scan displays, thickness testing and data logging, RF spectrum analysis with waveform storage, Time of Flight Diffraction (TOFD), flaw detection, and corrosion mapping. But what sets the Tablet UT™ apart is its on-board image replay and analysis capabilities. Since the Tablet UT™ is part testing system/part computer, it has the power and versatility not only to allow users to perform UT testing but also analyze the results seamlessly. No longer do users have to import test data onto an external PC equipped with UTwin™ to analyze results. Instead, they can remain in the field and perform their image replay analysis, which allows for further examination depending on test results.

Functions & Applications:
  • A, B, C-Scan displays
  • Flaw detection
  • Time of Flight Diffraction (TOFD)
  • Digital thickness displays
  • DAC/TCG • Corrosion mapping
  • Digital Strip Chart
  • Thickness data logging
  • FFT Spectrum analysis
Companion Scanners for Pocket UT™ System
R-Scan is a single axis encoded scanner used on flat or highly curved surfaces such as pipes and vessels. The R-Scan is a four magnetic wheeled device meant to be used on ferrous structures with the wheels assisting the unit to stay on track. A spring loaded, dry-coupled, UT sensor for monitoring the thickness of a structure comes complete with a cable for directly connecting to a Pocket UT™ System. Optional non-metal wheels are available. Learn more about our scanners  
Durable single axis encoded B-Scan can scan the circumference of pipe diameters over 3” and up to temperatures of 500ºF (intermittently). The scanner comes standard with a spring loaded .375” diameter dual element 5 MHz dual element transducer. Learn more about our scanners
The fully automated Mini Scanner is designed to inspect flat plate or pipe down to 3” in diameter. Inspection scanning speeds are as high as 7” per second, with an indexing/crawling speed of 3” per second. Featuring magnetic wheels, the Mini Scanner is at home scanning vertically or even upside down. The complete kit includes the Mini Scanner, 2-axis power supply, all umbilical cabling for power and water, and UT connectors to the Pocket UT™, optional transducers, bubblers and TOFD (TimeOf-Flight-Diffraction) wedges are available. Learn more about our scanners  
The TOFD (Time-Of-Flight-Diffraction) Scanner positions two angle beam transducers facing each other to transmit and receive the diffraction of ultrasonic waves generated in this technique allowing the user to view weld quality quickly. This highly efficient hand-held inspection scanner needs only one person to operate and is sensitive enough that an external pre-amplifier is not even needed. Learn more about our scanners
The M-Scan, designed with a linear-scan encoder for B-Scan and C-Scan, has a magnetic knurled wheel which maintains contact and does not slip on wet surfaces. Spring loaded arms ensure that the encoded wheel is always in contact with the surface in upside down, vertical, horizontal and circumferential positions. The versatile stainless steel pivot-arm design allows users to use different diameter probes ranging from 1/4″ to 1″. Learn more about our scanners  
The Manual X-Y Scanner, a traditional type dual axis operated scanner, moves strictly in X and Y coordinates. Internal X and Y encoders provide precise positioning information to the Pocket UT™ System. A universal sensor holder allows easy attachment of any UT sensor or sensor assembly. The standard sensor holder also has Gimbal & Swivel compliance built-in to allow scanning of contoured surfaces. An optional sensor bubbler holder kit is also available. The Auto X-Y Scanner (not shown), with internal stepper motors, provides automated movement of the scanner for position feedback. An “LSI” type sensor mount is provided so an LSI type Bubbler/ Gimbal & Swivel Transducer holder and assembly (optional) can be attached. A small, portable, AC or battery operated Scanner Control box provides the necessary power and motor drivers to operate the motorised X-Y stage. A scanner interface cable which connects directly to the Pocket UT™ motion control connector is also provided, for ease in setup and operation of the Pocket UT™ with the scanner. The scanning dimensions for both the Manual and Auto X-Y Scanner are approximately 15” x 17” (38 x 43cm) and they both come with suction cups for mounting to any smooth surface, optional vacuum operation suction cup assemblies and magnetic feet for attaching to ferrous metals.

The Tabletop Scanner is a small immersion tank with a 10″ x 10″ scanning envelope. X and Y axis are motorised with a manual Z Axis. This scanner comes with its own AC/DC powered motor driver interface. Metallic, Ceramic or Composite materials immersion inspection for internal defects, inclusion, delamination, dimensional thickness testing, cracks and bond quality. The small scanner provides the capability of establishing feasibility to test samples and offers the capability to develop testing procedures that can be applied to larger scanning systems.
