MFD 500 Ultrasonic Flaw Detector

The MFD500B is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high speed USB port.

The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.

The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

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 ...
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. [caption id="attachment_54" align="alignleft" width="150"] Ultrasonic Material Thickness Gauge[/caption] 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 ...
