United NDT also offers several types of Dual Matrix Array Probes as below:

1.5D and 2D PA Probes 

We provide all probes with the connector, cable type and cable length of your choice. Means: You can select your probe according to the specification and choose the connection type, the cable type and/or cable length.

We keep a huge stock of PA probes. Most of the standard PA probes are on stock. If a probe is not on stock, usual delivery time is 3 to 4 weeks.

How to define and choose your Matrix probe?

It is rather simple! Just focus on the frequency, number of elements, pitch and elevation and, if at all important, on the housing type. See the example below: 

The list below shows the Matrix PA Probes  currently available.

The second column includes the details about the cable used (110 Ohm or 50 Ohm) and the standard cable length (e.g. 2.0 m).

Other cable length and other cables (e.g. high duty cables with special protection) are also available on request.

When ordering you can specify cable length, cable type and the type of connector. In case you don't know the connector type, let us know the instrument you are working with.   

Suitable for inspections on coarse grain and granular material with transmission and receiving longitudinal waves.

Deep penetration in CRM (corrosion resistent materials) such as stainless steel, austenitic, other corrosion-resistant alloys, dissimilar welds. Also suited for cladded pipes.

These probes have excellent  signal-to-noise ratio for the materials as described above.

4. Wheel PA Probes

Applications:

  • manual scanning with integrated encoder

  • corrosion mapping (C-Scan), flaw detection and sizing

  • scanning of composites

  • for flat plates, curved surfaces and also big diameter pipes

Features:

  • efficient testing

  • little couplant necessary, because of silicon rubber wheel probe
