Phased-Array Ultrasonic Testing
(PAUT) Probe Ordering Guide

Introduction

Our phased-array transducers have frequencies ranging from 1 MHz to 18 MHz and can have between 8 to 256 elements. Here is a list of some of the type of phased array transducers we manufacture:

• 1D linear array transducers
• Concave array transducers
• 2D matrix transducers
• Dual 1.5D matrix transducers.

NextNDT offers a complete line of wedges that complement its phased array ultrasonic transducers. Designed to tackle any applications, our wedges come equipped with irrigation channels and easy fixation points for simple interfacing with scanning mechanisms.

Phased Array Ultrasonic Testing PAUT Probe naming rules

Transducer Types

Parameters Types

Primary Axis: Axis along which the individual elements are aligned for 1D linear probe
Secondary Axis / Elevation(Y): Axis perpendicular to the primary axis of a probe
Number of Elements (Primary Axis/n): Total number of elements aligned along the primary axis
Number of Elements (Secondary Axis/m): Total number of elements aligned along the secondary axis (Matrix Array only)
Primary Axis Pitch(P/Px): Center-to-center distance between two consecutive elements along the primary axis
Secondary Axis Pitch(PY): Center-to-center distance between two consecutive elements along the secondary axis (2D Matrix Array only)
Primary Axis Aperture(A/Ax): Dimension of the probe surface along the primary axis
Ax = (n–1) • Px + Ex
Secondary Axis Aperture(AY/Wpassive): Dimension of the probe surface along the secondary axis
Ay = (m–1) • Py + Ey

Wedge Types

Available in standard refracted angles of 0°, 45°, 55°, and 60° in steel for angle-beam inspections from 30° to 70°, SW or LW
Stainless steel screw receptacles provide a firm anchoring of probe to wedge
Wedges are available with IHC options: irrigation, holes, and carbide pins (for wear resistance)
Wedges are designed to perform manual or automated scans (IHC)
Custom wedges with specific refracted angles can be made-to-order; Wedge shape and contour can also be customized
