The Situation
The high precision and longevity of technical components such as vessels, piping systems, turbine shafts, and
vehicles in the automotive and aviation industry, is achieved in part by routinely
performed preventative in-service inspections (ISI), preferably using nondestructive
testing (NDT).
Powerful and intelligent ultrasonic testing systems
are indispensable for ISI inspections. These systems should be usable for stationary and
in situ applications, must be suited to the individual inspection task to ensure high
inspection standards, and they must be easy and quick to setup and use.
Our
Solution
With
the development of the PCUS 11 PC integrated ultrasonic board (PCB),
the Fraunhofer-Institute Nondestructive Testing (IZFP) has continued
their efforts to provide special ultrasonic PCBs.
The single-channel PCUS 11 is designed to meet the increasing
requirements with respect to high data acquisition rates and high
inspection speeds. In combination with custom software modules, the
user can inspect components effectively with high quality and
confidence levels.
Unconstrained management of vast amounts of inspection data for
demanding tasks in combination with modern software products, such
as CAD programs, reporting programs, data base programs, data
transfer programs, etc. are effortlessly managed using today’s
computing environments.
The
Advantages
-
All components required for ultrasonic testing
are contained on a single PCB, including transmitter, receiver, A/D converter, signal
processor, A-scan memory, etc.
-
Efficient, powerful BUS-interface
(PCI/Master DMA) allowing high data acquisition and high data transfer
rates.
-
Selectable display of RF or rectified A-scans through DSP
signal processing; other processing algorithms available upon
request.
-
Various signal trigger
options.
-
Comfortable data analysis and data management through
PC-integration.

Software
Automated Inspections
The CPS software is a reliable software module that has been proven to provide setup, data
acquisition and analysis (A-scan, B-scan, C-scan, and composite C-B-D presentations), and documentation of results for ultrasonic examinations. Up to four PCUS 11 boards (four channels) and a scanner can be controlled using the CPS software.
SAFT
Analysis Software
If required, flaws can be characterized using Synthetic Aperture Focusing
Technique (SAFT), to more accurately display size, location, and accumulation of
detected flaws.
Manual
Inspections
Standard manual ultrasonic inspections can be performed using the
PCUSWare32© software.
This software package also permits recognition, diagnostic, and control of a
maximum of four PCUS 11 boards.
Desktop layout, display size, and resolution are
customizable. The PCUSWare32© software allows the display and hardcopy printout of
all recorded A-scan images. Recorded data along with pertinent setup and examination
parameters can be stored and retrieved at any time. A databank permits the
management of search units and their associated individual data. Software support
for system calibration.
