Reference Blocks

V1 and V2 – are common used reference (calibration) blocks for UT testing.

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.

But there are available other types of blocks in accordance to different standards (ISO, DIN, etc.). If need UT or PAUT blocks of other standards, please send enquiry.

Advantages:

• High quality
• Competitive price
