Ultrasound probes used - ultrasonic piezoelectric transducers for
pulse flaw detectors.
The dimensions of the operating area of the screen is 115 х 86 mm.;
Electrical power is supplied from the following sources:
- AC power from 100 to 250 V, a frequency of (50 ± 1) MHz;
- 11,1 V, recommended capacity of at least 6,6 Ah.
5 . Operating principle
Operating principle of flaw detector is based on the ultrasonic
contact NDT method, which uses the properties of ultrasonic
vibrations to reflect from the borders between materials with different
acoustic impedance. The ultrasonic transducer emits ultrasonic
impulse into the tested object. Reflected from the defects or the
product surface the echo signals are received by the ultrasonic
transducer. The
amplification, digitization, processing and output to the display.
Displays echoes received by the flaw detector is performing as
scanning of type A (A-scan) as well as images of cross sections of
tested objects in form of B-scan.
