EMAT Thickness Gauge NOVOTEST UT-3M-EMA


EMAT Thickness Gauge NOVOTEST UT-3M-EMA is used to perform thickness measurement of metal products, and is especially useful in cases where traditional methods such as piezo-ultrasonic, laser-optical, mechanical, or X-ray, etc. are not suitable.

Electromagnetic-acoustic (EMA) technology for measuring thickness is based on the principle of excitation of ultrasonic waves by the generator of the device’s probe into the material, and fixing the path time of ultrasonic waves in the material.

Electromagnetic-acoustic (EMA) thickness gauge UT-3M-EMA allows user to measure the thickness of metal products without of couplant, and under condition where there is a layer of coating or rust, which is an advantage compared with standard ultrasonic thickness gauges. It should also be noted that the EMA thickness gauge allows measuring thickness through a significant gap – up to 6 mm, thus it becomes possible to measure thickness without contact.

By special order, the EMA thickness gauge can be manufactured with dustproof and waterproof protection with IP65 rating. The thickness gauge is supplied with high-capacity lithium-ion battery which has long working hours. Customer can also request by special order for a higher capacity battery which allows up to 30 hours of operation from single charge.

EMAT Thickness Gauge NOVOTEST UT-3M-EMA also comes with special software for operate with the stored data in the device, for subsequent transfer of data to a PC for further processing in convenient formats.

  • Unique automatic operation mode of the thickness gauge. 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 display. Therefore, even a new user will be able to accurately and easily measure the thickness of various products or metal samples under automatic operation mode.
  • The device implements the B-scan mode, which allows user to get the product profile like a picture that is easy to read. Using a specialized carriage for the probe, it becomes possible to scan extended objects and obtain a thickness profile.
  • There is expert control mode where user can carry out manual measurements using all known methods– using the autocorrelation function (ACF), measurement between two maximum signals in the gate, echo by zero crossing, echo-echo passing through zero.
  • There is a special auto calibration mode available on a standard thickness sample.
