Transducer Crystal is used in products for Sci-Fi Movies and NDT

“Fire up the tractor beam,” is a common phrase in many popular sci-fi movies. ­­­­­­­­These tractor beams use crystal to generate power. Did you know that transducers used in nondestructive testing also use crystal?

Many NDT transducers use piezoelectric ceramic crystals to generate mechanical energy. This process is used in ultrasonic testing. The power it generates bounces electrical signals to detect flaws and provides inspectors with valuable information.

How They Use Crystals

Crystals are cut in a lattice structure to allow the crystal to adjust and morph while having electrical current pulsed through it. Due to the change of structure, this creates an ultrasonic wave. This wave moves through the tested object and can be detected to report thickness gaging.

Many different types of transducers are made to provide testing for a wide array of inspections.
