OEM solution

Ultrasonic inspection device for system integrators

PROlineUSB is our ultrasonic solution for OEM customers. System integrators use the ultrasonic inspection device for the economical and simple realization of a process-safe inline or offline inspection system.

The lowest level of our involvement in your inspection system is the use of the ultrasonic device with the help of the SDK (Software Development Kit for C++) to integrate and control the device in your software structure for the inspection system. This gives you free control of all ultrasonic channels with their apertures and parameters as well as the 2 rotary encoder interfaces and the existing I0’s. Thus, a simple location-based data acquisition is easily achieved by synchronization to the pulse repetition frequency of the ultrasonic device.

Because we have realized various ultrasonic software for various applications for decades, our range of standard software with extensive functions is comprehensive. With our plug and play modules you can quickly solve your application.

Choose between a simple IO module for sorting components in OK/NOK, a single line scan module up to area scan modules with online and offline evaluations.

We will be happy to advise you on this individually.

With PROline you choose a proven, reliable, user-friendly and flexible ultrasonic solution for you or your customer.

Intuitiv und modular

PROlinePLUS inspection and evaluation software

The modular PROline inspection and evaluation software for imaging display and evaluation of ultrasonic inspection data focuses on user-friendliness. Its special feature is the reduction of complexity with the focus on a clear display of the test results and, if desired, an automatic evaluation of these. The safe operation of the inspection technology thus requires only a minimum of training time.

With the PROlinePLUS software modules, the PROlineUSB becomes an efficient, PC-based inspection system with Windows interface for mechanized and automated ultrasonic inspection in production as well as a stand-alone solution for applications in the laboratory.

The software has a modular design and can thus be ideally adapted to the user’s needs: From simple OK/NOK evaluation via I/Os up to complex imaging ultrasonic testing as part of a fully automated production line in the sense of Industry 4.0. The automatic evaluation and ISO-conform result documentation saves time and creates inspection reliability. Available software modules include:

    • Line scan (PROline_Line)
    • Area scan (PROline_Area)
    • Grid scan (PROline_Grid)
    • Inspection plan definition (e.g. definition of scan resolution, definition of inspection data evaluation, definition of ultrasonic files for inspection plans, simple to complex inspection sequences, activation of switching outputs for sorting and marking of components depending on the inspection result)
    • Inspection and inspection data display (e.g. A-scan, line scan, area scan, grid scan, amplitude and time-of-flight evaluation, wall thickness measurement)
    • Controlscript for communication with external periphery in the form of sequence controls
    • I/0 incl. logic (e.g. threshold crossing, optical display of good/bad evaluations on the screen)
    • Test data evaluation online / offline
    • Intelligent A-scan for storage of all A-scans depending on events, e.g. threshold crossings
    • PROlineSDK developer package for C++
