Description

Reference Block V1 allows to:

determine the insertion point of ultrasonic oscillations and distance from the piezoceramic plate to the probe housing with accuracy ± 0,5mm;
define the angle of input of the ultrasonic oscillations with accuracy ±1 angle degree;
define the uncontrollable (dead) zone (for steel) straight beam ultrasonic piezoelectric transducers;
determine the linearity of ultrasonic scanning horizontally;
configure the speed and sensitivity of the scan of straight beam, angle beam and dual element piezoelectric transducers.

Reference Block V2 allows to:

calibrate the scanning of flaw detectors through the expansion velocity of ultrasonic waves, working with straight beam piezoelectric transducers;
calibrate the scanning of flaw detectors through the expansion velocity of ultrasonic waves, working with angle beam piezoelectric transducers;
set conditional sensitivity of ultrasonic flaw detectors with straight beam and angle beam piezoelectric transducers;
determine the output point of ultrasonic oscillations and distance from the piezoceramic plate to the probe housing;
define the angle of input of the ultrasonic oscillations into steel.
