PAUT Probe Ordering Guide

Introduction

Our 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.

How to order PAUT probes?

Use the naming rules below to order probes by choosing a type under each rule:

 

  • Frequency
  • Array Type
  • Number of Elements
  • Elementary Pitch
  • Elevation
  • Casing Type
  • Cable Type
  • Cable Length
  • Connector Type
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

Custom Probe Requirements

To order custom phased array transducers and probes to match your specific applications and geometries, we need the following information:

  • Application
  • Comparable UT single element transducers
  • Frequency
  • Number of elements, pitch, and elevation
  • Array shape (flat, curved) Curved in active dimension
  • Curved in passive dimension (elevation focused)
  • Casing type (S series, A series, others)
  • Cable jacket required
  • Cable length
  • Connector Type
  • Housing restrictions and/or size constraints
