Phased Array probes

United NDT offers several type of Linear PA Probes as under:

(see also under Special PA Probes)

1. Standard Universal PA probes
2. Small footprint Linear PA Probes
3. Deep penetration Linear PA Probes
4. Near Wall Linear PA Probes
5. Immersion Type Linear PA Probes 
6. Linear PA Probes with integrated wedge

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 probes is not on stock, usual delivery time is 3 to 4 weeks.

How to define and choose your 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:

Standard Universal Linear PA Probes

The list below shows all the Standard Linear PA Probes currently available. There are some more linear probes under Special PA probe. 

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. If you don't know the connector type you may just specify the instrument you are using.

1. Standard Universal PA probes

Applications:

• angle beaming with shear or longitudinal waves (depends on wedge)
  

• inspection of: welds, pipes, castings, forgings, machined components (manual and automated)
  

• detection of flaw and sizing

Features:

• delay line and wedge concept for maximum flexibility due to versatility
  

• high measuring range 

2. Small footprint Linear PA Probes

Applications:

• inspection of small test objects or pieces with limited areas of access
  

• special application (aerospace): detection of scribe marks through coating
  

Features:

• different designs for different applications

• special delay lines and wedges

3. Deep penetration Linear PA Probes 

Applications:

• inspection of thick parts (also in "noisy" material)

• straight and angle beam for shear or longitudinal waves (depends of delay line)
  

• inspection of: welds, pipes, castings, forgings, machined components (manual and automated)
  

• detection and flaw sizing

Features:

• delay line and wedge concept for maximum  flexibility due to versatility
  

• high depth range of measurement

4. Near Wall Linear PA Probes

Applications:

• typical used for C-Scan inspection of corroded parts and composites (delamination, disbonding and porosity checking)   
  

Features:

• build with small dead zone at front and rear side of the probe

• particularly suitable for corrosion mapping and composites 

5. Immersion Type PA Probes

Applications:

• for immersion inspection

• automated scanning of thin material (e.g. tubes, pipes, plates and the like)

• inspection of composites (delamination, debonding and the like)

• inline inspection (thickness gaging and flaw detection) 

Features:

• different designs for different applications

• high accuracy

• ideal for automated scanning

6. Linear PA Probes with integrated wedge

Applications:

• for manual inspection

• flaw detection and sizing

• inspection of small test pieces, or pieces with limited areas of access 

Features:

• probe and wedge in one case 

• user friendly

• compact size

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.
