Two types of transverse wave EMA transducers – with radial and linear polarization, based on the developed pulsed electromagnet technology, are used.
Operation with the permanent magnet transducers S7392 and S7394 by connecting a special adapter.
Measurements can be conducted without pretreatment of the surfaces of the inspected objects and without use of coupling liquid.
Thickness measurement of metal objects through corrosive and paint coatings of up to 1.5 mm in thickness. Instrument's screen displays a thickness value of the metal object without considering the coating if the coating thickness is 1.5 mm and thickness value of the object being inspected is up to 15 mm.
Ultrasonic thickness measurement of the objects through air gap, by means of fastening of the EMA transducer in the special-purpose movable carriage.
Small aperture of the EMA transducer (8 mm) allows to inspect of the small-diameter pipes (from 15 mm).
An innovative technical solution frees the design of the EMA transducer from strong permanent magnets hence they are replaced with pulsed electromagnets. It excludes an effect of strong adhesion of the transducer to the ferromagnetic materials, as well as ensures safe operation of the transducer and simplifies scanning procedure, thus simplifying practical use of the thickness gauge during manual UT inspection.
Scanning the object being inspected.
Operation in the display mode representing the measurement results in the form of digital values or in the mode with graphic imaging of A-Scan of the signal.
B-Scan mode to display a profile of the object being inspected on the instrument's screen.
