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 non-destructive testing (NDT).

Powerful and intelligent ultrasonic testing systems are indispensable for ISI inspections. These systems should be usable for stationary, in situ applications and must be suited to the individual inspection task to ensure high inspection standards. In addition, they must be easy and quick to setup and use.

Solution

We provide standard and custom-designed ultrasonic equipment and components for a large variety of testing applications.

Fraunhofer IZFP's latest development UNIUS, a single channel ultrasonic Pulser/Receiver (P/R) Board can be easily integrated by ITK Software in customer GUI.

Q NET also provides UNIUS P/R Boards already integrated in ruggedized Notebooks for rough industrial environment which can easily be adopted to the customer's needs.

The receiver has ≥ 100 dB gain range and 0.1 dB resolution with 0.5 - 20 MHz bandwidth. The pulser is negative square wave 0-300V. For more details see section Technical Data
