The principle of operation of the device: The principle of operation of the flaw detector is based on the excitation of eddy currents in the controlled product and the subsequent release of a signal at the output of the converter, the amplitude and phase of which are determined by the secondary field of eddy currents. Design features and advantages of the VD-90NP flaw detector. The device has a small-sized case, which ensures its lightness, ergonomics and allows you to mount it on your belt or on your arm. The measurement is performed using a remote converter connected by a flexible cable. There are several types of converters for eddy current flaw detection of products made of different materials and different geometries. The large and bright display displays the selected operating modes and measurement results in text and graphic form.
