Description
EMAT Thickness Gauge NOVOTEST UT-3M-EMA
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.
So, the technology is similar to the most common piezo-ultrasonic method, however, the EMAT Thickness Gauge NOVOTEST UT-3M-EMA thickness gauge has several advantages:
CONTACTLESS MEASUREMENT
The electromagnetic-acoustic thickness gauge allows user to measure the thickness of metal products with one-way access without using couplant through a substantial gap (up to 6 mm). This significantly reduces the material- and laboriousness of the measurement process.
EMA technology generates waves directly in the material (ferromagnetic and paramagnetic), thus allowing measurements to be carried out under a coating or with a poorly prepared surface, which may not be feasible with traditional methods.
HIGH TEMPERATURE PROBES
EMAT Thickness Gauge NOVOTEST UT-3M-EMA can be equipped with probes for operation on surfaces heated to a temperature of 600 °C, which makes this device the best, and in some cases, the only possible solution.
A significant advantage over competitors is the range of measured thicknesses. The EMAT Thickness Gauge NOVOTEST UT-3M-EMA allows measuring walls from 0.5 mm to more than 200 mm, depending on the probe used.
THICKNESS GAUGE EXECUTION
EMAT Thickness Gauge NOVOTEST UT-3M-EMA is made in a durable and lightweight metal case. By special order, the thickness gauge can be made in dust and waterproof design (IP65). The thickness gauge is equipped with lithium-ion high-capacity batteries, which allowed for a long battery life. By special order, the battery capacity can be further increased, which will allow user to operate up to 30 hours from a single battery charge.
AUTOMATIC OPERATION MODE AND VARIOUS TYPES OF SIGNAL DISPLAYING
The EMAT Thickness Gauge NOVOTEST UT-3M-EMA implements a unique operating mode – the device automatically analyzes the measured signals, selects the required measurement method, adjusts the parameters of the receiving path and displays the measured thickness on the device’s screen. Even an unskilled user with this mode will be able to accurately and rapidly measure the thickness of various metal structures and products.
Also, EMAT Thickness Gauge NOVOTEST UT-3M-EMA comes with special software for operate with the archive of the device, and the subsequent transfer of data for processing in convenient formats.
