Velograph II

Software PDAs ultrasonic flaw Velograph II

Ultrasonic flaw detector Velograph II (Velograf 2) is designed to search for discontinuities and homogeneity of the material and determine their coordinates in products made of metals and plastics. The device allows you to control welds, measure the thickness of the walls of products, conduct a search for places of corrosion, cracks, internal delaminations and other defects.

It consists of an electronic unit and a PDA connected via a wireless bluetooth interface. As a PDA can be a device with the operating system Android 4.0 and above, with a screen diagonal of at least 4.7 inches, equipped with bluetooth.

The basic package includes a tablet PDA with a diagonal of 7 inches.

The full functionality of the software is achieved after connecting to the included electronic unit, for which you need to press the “On” button and in the opened window select the associated electronic unit (if necessary, select another button “Search”).

Features of program management:

- a single click on a numeric parameter or its signature makes the parameter active

- to enter values ​​of active numeric parameters, click them again

- to change the numerical parameters, it is convenient to use the "slider", single clicks on which change the active parameter to the minimum step, and holding changes the parameter continuously (the faster the further the "slider" is rejected from the middle)

- to change the number of gates or bind them to the gain, double-click on the active gate switch - this opens the corresponding menu

- gates and points of ACG and ARC curves can be dragged across the scanning screen, gates can also be stretched

- when you click on the scale, the menu for selecting its display units opens

- individual settings are opened when you click on the button in the upper right corner of the screen

Features ultrasonic flaw detector Velograph II:

- a full-fledged two-channel ultrasonic flaw detector with the ability to work with piezoelectric transducers from 1.5 to 10 MHz according to separate and combined control circuits, entered in the State Register of Measuring Instruments under number 68124-17

- compactness and lightness (electronic unit weighing less than 170 g)

- the ability to control steel by direct transducers of thicknesses from 4 to 300 mm, inclined transducers 65 and 70 degrees from 3 to 40 mm

- independent parameters for each of the two amplifiers, for each of the two generators in the same setting

- gain change up to 84 dB in 1 dB steps

- up to 4 strobes with the ability to bind thresholds to the adjusted gain, with automatic and vibro alarm for exceeding

- The presence of RFG up to 8 points with a dynamic range of up to 84 dB

- ability to build an ARC curve up to 128 points

- optional optional on / off display of coordinates, distance along the beam and signal amplitudes

- the horizontal scale can display the signal delay time, Y coordinate, depth and X coordinate

- convenient display of the grid of the horizontal scale, tied to the integer values ​​of the displayed units

- presence of envelope

- the ability to "freeze the signal"

- the current setting of the device and up to 200 more saved settings are stored in the electronic unit, which allows you to reconnect with other PDAs with the installed software and continue working without the need to reconfigure

- control results are saved as images in PNG format, which allows you not to use special programs for viewing or printing them
