MVX Ultrasonic Thickness Gauge

MVX multi-mode ultrasonic thickness gauge measures through painted or coated surfaces for providing thickness measurement of metal substrates without removing coatings. The MVX equipped with multiple viewing options is a complete set for inspection

  • The physical size, weight, and display resolution are just a few of the benefits of the MVX.
  • The adjustable square wave pulser provides the flexibility necessary for both high resolution and penetration requirements.
  • The MVX is equipped with multiple viewing options to provide users with a complete set of inspection tools: (RF waveform, +/- Rectified waveform, Time based B-Scan, and Large Digits).
  • The A-Scan rectified mode is commonly used for detecting flaws/pits in pulse-echo mode and measuring thru-paint and coatings in echo-echo mode.
  • The time-based B-Scan feature of the MVX displays a cross section of the test material. It is commonly used to display the profile of the bottom surface of the test material.
  • Built-in hardware AGC gain control for thru- paint measurements in multi-mode operation.
  • The variety of calibration options is just one more example of MVX's overall versatility.
  • The MVX has the ability to store 64 custom user-defined setups. All factory setups can be selected, edited and saved to any setup location.
  • MVX is equipped with an alpha-numeric data logger to provide increased versatility for those custom reporting needs.
  • The built-in transducer type’s offer increased linearity between transducers.
  • The high speed scan feature speeds up the inspection process by making 32 measurements per second.
  • Remove transducer from the test material and display the minimum measurement scanned.
  • Visual alarm with Hi and Lo limit settings for specific application tolerances.
  • Use the find feature to locate the detection point, while automatically adjusting the display to bring the signal into view.
  • MVX also comes complete with our Windows® PC software for transferring data to and from a PC.
  • A basic Flaw Prove-Up Mode for use with angle beam style transducers.
  • Multiple language support
  • 2 year limited warranty

  • How To Choose An Ultrasonic Thickness Gauge -Part II
    How To Choose An Ultrasonic Thickness Gauge -Part II
    The decision on whether you need to measure : 1. Thickness of sheet metal 2. Evaluate the onset of corrosion in metal fabricated structures 3. Thickness of small diameter pipes such as boiler tubes, automotive pipes etc amongst others, will decide which thickness gauge instrument you should purchase to satisfy the application. A thickness gauge is an investment in quality production of components, to test quality of product purchased and finally to ensure a higher lifetime of asset by identifying corrosion. Purchasing a world class quality instrument such as Dakota ultrasonic thickness gauge ensures that your teams are utilizing product which will provide consistency and repeatability in measurements ensuring that the process of quality assurance or quality testing can be inducted into your organization as a process and not as a daunting task. Many a times questions are asked give us an ultrasonic thickness gauge instrument which is easy to use , will provide accurate readings and can withstand the test of time in adverse conditions such as oil, heat etc. however, at the same time the next point addressed is that it should be the lowest cost instrument. As mentioned above, purchase of a thickness gauge should be considered an investment that provides a ROI i.e it should be viewed as a method of cost savings by ensuring quality and therefore avoidance of rejections, as a method to periodically check against or rather the onset of corrosion to ensure preventive maintenance of high value steel structure assets. Given the repetitive nature of quality assurance or the size of the assets that are usually under test, it becomes even more pertinent that the thickness gauges utilized should be advanced enough to allow easy and quick handling by engineers or technicians at any level. Instruments such as the CMX Ultrasonic thickness gauges or the MMX6 ...

  • How To Choose A Material Thickness Gauge - Part I
    How To Choose A Material Thickness Gauge - Part I
    Thickness gauges are utilized where a micrometer or vernier caliper cannot be utilized – for measuring thickness of large sheets of metal or other substrates which can otherwise not be measured using the above devices. A thickness gauge works on the principle of ultrasonics, i.e a signal is sent into the substrate through the transmitter  of an ultrasonic transducer which when received allows the thickness of the substrate to be measured. While all this sounds so simple, should all ultrasonic thickness gauges not be the same? Which leads to the questions – 1.  what is the type of substrate under test ? egg, steel, aluminum, iron, titanium, glass etc.2.  What are the conditions in which the thickness gauge will be used, will there be dust, oil, water ?3.  Is it a simple sheet of material or a final product ?4. How thin or thick is the product or material  ?5. Is it a tube , sheet or a block ?6. Are measurements required to be conducted on the same type of material each time or do the materials which are being tested keep on changing ?7. Does the material have a coating or not ?8. What is the accuracy required ?9. Is datalogging required ? amongst others. Knowing the answers to the above decides : What we need from an ultrasonic thickness gauge in terms of capability.What is the kind of ultrasonic transducer required to efficiently carry out the measurements and with accuracy.Thickness gauges are available in options ranging from general purpose thickness gauges to precision thickness gauges with accuracy of 0.001mm. also, apart from general purpose thickness gauges, options are available of multimodal thickness gauge which go beyond the standard pulse echo mode introducing the echo – echo mode for measuring through coating. The options go forward to include thickness gauges that also measure coatings apart from ...
