New model ultrasonic flaw detector, combining advantages of device UD2V-P45 with the expanded functions to measure and record results of the testing:

simultaneous measurement of amplitude and coordinates position of a maximum signal;

simultaneous measurement of distance on-beam and defect coordinates for angle trasdusers;

a mode of record bending around a signal maximum in a examination area, with B-scan display;

the expanded memory options and results of the testing;

software support for several databases of the testing reports on the personal computer with ReportConstructor function

full-screen an operating mode (LD-version)

possibility to connect one of 7 built-in matching elements, for optimum work with any transducers

The algorithm of record realized in the device bending around a signal maximum differs from similar modes in similar devices of other firms. As a rule, it is a so-called mode "Peak freezing", when the device memory the maximum value of amplitude of a signal in each point of range. Unlike such mode, realized in UD2V-P46 the method allows to construct bending around remembering only on one point in each probing impulse - by position and value of the maximum amplitude of an echo-signal in a testing zone.
Such mode gives the chance to receive, for example, the move diagramme maximum a signal at cross-section scanning of defect in welded joints and to estimate its conditional extent, and also it is easy to define reflector coordinates at the maximum amplitude of the reflected signal.

 

One more considerable improvement in new model - increased to 100 quantity of options, with record of the A-signal and possibility to input a name of adjustment from the device keyboard, and as possibility of preservation to 750 results of the testing (15 files on 50 results). Each result represents the full report of the testing and consists of an A-signal, bending around a maximum (if the result is kept in this mode), digital value of result of measurement (amplitude and coordinates, distance on a beam and coordinates or speed ultrasonic), all parameters of work of the device, date, time and a name of the result entered from the keyboard of the device. All results can be looked through and renamed further both in the device, and by means of the software on the computer. Software UdReport, allowing completely automating processing results of the testing is for this purpose intended, dividing them on different bases of reports and defining various additional parameters of the testing on the basis of the identifiers containing in a name of result. Besides, the program has function of the designer of the reports, allowing creating printing forms of reports of any kind depending on requirements of the concrete user.
