Phased Array Technology
Definition - What does Phased Array Technology mean?
Ultrasound beams are used in phased array (PA) ultrasonic equipment, which is considered an advanced method of ultrasonic testing. This technology finds applications in medical science and non-destructive testing.
This method is more accurate at finding flaws in manufactured materials such as welds. The ultrasonic beam in a PA probe can be focused and swept electronically without moving the probe. The beam is controllable because a phased array probe consists of multiple small elements, each of which can be pulsed individually at a computer-calculated timing.
Corrosionpedia explains Phased Array Technology
The ultrasonic beams are controlled through computer based software programs in the phased array (PA) technology that control the acoustic characteristics such as the refracted angle, focal distance and aperture without moving the probe. When compared to conventional ultrasonic testing (UT) methods, this technology opens a series of new possibilities such as:
- Multiple refracted angles and focal distances are generated simultaneously by a single search unit.
- Ultrasonic beams are electronically moved over the length of the PA probe, without any mechanical movement.
- By using multiple ultrasonic beams, the probability of detection is increased.
- Automated or semi-automated inspection methods can be implemented more efficiently.
