Phased Array Ultrasonic Testing
A simple definition for Phased Array Ultrasonic Testing is ‘an electronic method of generating, receiving and displaying an ultrasound signal’. The process uses a conventional probe cut into many segments, which are individually ‘excited’. It does not change the physics of ultrasonics but can be accurately manipulated to provide precise data about the materials under test. Sophisticated technology allows multiple elements to steer, angle, multi-focus and scan beams using a single transducer assembly.
The principles of ultrasonic technology have been known for many years but it is only in the last 50 or so that knowledge been harnessed to great and diverse effect where surface and depth of any description needs to be tested and inspected.
Phased Array Ultrasonic Testing is also extensively utilised in the food processing, medical, biological, agricultural and pharmaceutical sectors for the same purposes as every other division– the gathering of vital data essential for product performance, health & safety, research and development.
