EMAT Thickness Gauge NOVOTEST UT-3M-EMA

Description

The EMAT thickness gauge uses advanced electromagnetic-acoustic technology to measure metal thickness, even in cases where traditional methods like piezo-ultrasonic or laser-optical are not applicable. The technology allows measuring the thickness of products using ultrasound without couplant, through a coating or air gap.

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. 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.

Measurement possible through paited, oxidized or oily surfaces ,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, the thickness gauge 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.

Measurement range, a significant advantage 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.

Automatic operation mode, 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. By default, the signal in the device is displayed like an A-scan, and the available operating modes allow the operator to evaluate the signals using different methods (PEAK-PEAK, FRONT, ECHO, ECHO-ECHO). Also the B-scan mode is implemented in this thickness gauge, which allows user to get the product profile like a graphical, convenient for perception. Using a specialized carriage for the probes, it becomes possible to scan extended objects and obtain a thickness profile.
