EMAT Thickness Gauge NOVOTEST UT-3M-EMA is a new development of the NOVOTEST company, which will allow our users to solve not only the standard tasks of testing the thickness of metal products, but also to carry out tests in cases where traditional methods, such as piezo-ultrasonic, laser-optical, X-ray, mechanical, etc. – not applicable.
Electromagnetic-acoustic (EMA) technology for measuring thickness is based on the excitation of ultrasonic waves in the material by the generator of the device’s probe, and fixing the path time of ultrasonic waves in the material.
Advantages
- The thickness gauge boasts a unique automatic mode that sets it apart from competitors. The mode that makes it easy for anyone to measure metal thickness quickly and accurately. The instrument automatically analyzes the signal, selects the correct measurement method, and adjusts the settings. Users see the thickness result displayed in large numbers.
- The gage also features a B-scan mode. This mode gives users a visual profile of the product, like a picture, making it easy to read. Using a special probe cart, users can scan larger objects and obtain a detailed thickness profile.
- To sort products based on set thickness limits, the gauge offers a special control mode. Simply set the minimum and maximum thickness values and get a graphical display of the results. An alarm sounds if the measured thickness falls outside of these limits. This mode also helps evaluate corrosion damage as a percentage of the product’s original thickness.
- For expert testing, operators can manually measure thickness using a variety of methods, such as the autocorrelation function (ACF), measuring between two peaks in a gate, zero-crossing, and echo methods.
