Basic Info

    Model No.: OD28*ID25*40mm PZT-52

Product Description

Piezoelectric ceramic tubes

Electrode direction: Radial direction



Applications: NDT Non destructive Testing


Non-destructive testing (NDT) is a testing method to inspect the surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials.


There are many kinds of ultrasonic flaw detectors, but in the actual flaw detection process, pulse reflection ultrasonic flaw detectors are most widely used. Generally, in homogeneous materials, the existence of defects will cause the discontinuity of materials, which often results in the inconsistency of acoustic impedance. From the reflection theorem, we know that ultrasound will reflect at the interface of two media with different acoustic impedance. The magnitude of the reflected energy is related to the difference of acoustic impedance of the media on both sides of the interface and the orientation and size of the interface.
