The phased array detection solution of the wind power variable propeller bearing adopts phased array technology to realize the efficient and rapid detection.
Fast detection speed. Due to the array elements in the probe is time delay energization by electronic scanning, it is much faster than the mechanical scan of the conventional probe when doing linear scan.
Reliable detection result. The rapid sequential excitation of multiple elements in a phased array probe, the radiated sound field is equivalent to the continuous mechanical displacement and steering of a single element probe, which greatly improves the reliability of detection.
High detection sensitivity. The focus of the ultrasonic beam increases the detection signal-to-noise ratio; in the sectorial scanning, many defects that are difficult to distinguish due to the directionality of the crack can be detected; a large amount of A-scan data increases the resolution of defects at various angles.
