Linear Phased Array Probesfor Angle Beam Inspection withReplaceable Wedges

What is a Phased Array Probe?A phased array probe can be compared to a large singleelement transducer whose active area has been sub-divided into small segments or elements. When connectedto appropriate instrumentation, the beam from the phased

array is steered and focused electronically by sequentiallyfiring the elements of the array. Angle and focal depth aregenerated electronically by the instrumentation and canbe changed on each pulse repetition.

•  Variable virtual probe size (aperture)

•  Variable beam angle

•  Variable focal depth

•  Beam indexing (scanning) for large area coverage

•  Low noise wedge design

•  Standard Hypertronics connector

Key Features 

Advantages of Angle Beam Phased Array Probes•  Eliminate multiple inspections with fixed angle probes.

•  Increase sensitivity and signal to noise ratio withelectronic focusing.

• Inspect hard to access areas from a singlecontact point.

•  High sensitivity, broadband piezocomposite elements

•  Reduce mechanical and manual manipulation.

•  Probes may also be used for immersion and watercolumn testing.

•  Replaceable wedges maximize service life of thearray probe.

• Replaceable wedges enable a broad range ofapplications for each probe.
