Introduction to Phased Array Technology High-Speed Scans with No Moving Parts The distinguishing feature of phased array ultrasonic testing is the computer-controlled excitation (amplitude and delay) of individual elements in a multielement probe. Through software, the excitation of multiple piezocomposite elements generates a focused ultrasonic beam, enabling the dynamic modification of beam parameters such as angle, focal distance, and focal spot size. To generate a beam in phase by means of constructive interference, the various active transducer elements are pulsed at slightly different...

Custom Probes Phased Array Probes Olympus can manufacture custom phased array probes to suit specific applications and geometries. To develop your custom probe, we will need to know: • Application • Comparable UT single element transducer • Cable length • Number of elements, pitch, and elevation • Cable jacket required • Connector style • Array shape (flat, curved) • Probe type (angle beam, immersion, integrated wedge, matrix) • Housing restrictions and/or size constraints -- Curved in active dimension -- Curved in passive dimension (focused) Variable angle Dual linear Internal focus Phased...

Laterally Focused Arrays (CCEV) These probes for girth weld inspection used with the PipeWIZARD system or COBRA® scanner have curved elements in the passive plane, focusing the beam in the lateral direction. An integrated lens permits the use of standard wedges. These cylindrically-focused probes significantly reduce oversizing and excessive repair. Their capacity to discriminate small indications is a major advantage when sizing the length of an intermittent defect using interaction rules. In addition, beam energy is better maintained in small pipe/thin wall applications. Advantages • PWZ1...
