Multi-element probes

Multi-element probes Sonatest offer many possibilities with a wide choice. Three families are available:

• Integrated cable X series probes which have the advantage of being more economical while providing excellent performance
• DAAH series probes detachable cable which have the advantage of having an interchangeable cable as the traditional single-element probes
• Handy wheel probes for acquisitions composite or corrosion mapping. All these probes are compatible with most multi-market elements equipment

Multi-element ultrasound – phased array

The multi-element ultrasound technology is a powerful technology directly inspired medical technology. It generates multiple angles simultaneously and see real-time images on a screen. It is extremely fast detection as a localized indication appears as a ‘spot’ on the screen. It is also accurate for sizing and positioning thanks to the many possible views and measurement cursors. The covered volume is more understandable and inspections can be recorded.

The multi-element technology is the use of translators divided into several small elementary translators and excite each of these elementary translators with a time lag (delay) that will create a beam. By modifying a shot at the other delays, the beam can be moved, or changed in its direction. This creates either a ‘scanning linear, a’ scan ‘sector.

X1 Series – miniature and sub-miniature sensors

X1 range is small probes for aerospace, limited access to jobs. Key applications include monitoring ‘scribe line’ for manufacturers and aerospace companies.

X2 series – Probes for general applications

Compact probes of general purpose design, suitable for sector scanning applications.

X3 series – wide Probes

These sensors are ideal for line scan applications (L-Scan or E-Scan). They can also be used for sector scans (S-Scan). These probes are particularly suitable to perform scans’ multigroup ” for enabling the devices.

X4 Series – Miniature sensors with integrated shoe

An equivalent conventional design with corner single element translators.
A good choice when a compact bundle is required.

X5 Series – Medium Probes – AWS, high temperature and high penetration

Probes high energy low frequency for applications where penetration must be deep enough and more general inspections.

Généralités

The sensors are available as standard with IPEX connector (for VEO or Omniscan) and a 2.5m cable length. They can be supplied with 5m cable with a larger delivery.

Hooves (except X4 series) are fixed by 2 or 4 screws.

The hooves are defined by the refracted angle, typically:

• For longitudinal waves: 18-20 ° cutting angle corresponds to a refracted angle of 50-60 °
• For transverse waves: 33-38 ° cutting angle corresponds to a refracted angle of 50-60 °

Wheelprobe

The famous Phased Array patented wheel Sonatest is the result of many years of research and meticulous development. It is characterized by a wide tire in deformable rubber whose acoustic impedance is matched to that of water. This generates a low pressure coupling in the test piece, and therefore good quality results without the need for freezing or to large amounts of water.

It is ideally suited to manual scanning large flat or slightly curved surfaces. A central bearing cushioning spring, ensures even pressure coupling along the sensor, even when controlling narrow surfaces. Incorporating a multi-element array of 64 elements with a resolution of 0.8 mm and a high resolution position coder, the wheelprobe provides high quality data, with high accuracy. The area covered is 50mm. For applications that require the coverage of very large areas, we propose a wheelprobe 100 mm using a multi-element array of 128 elements, with a resolution of 0.8 mm and is optimal for control plane parts having a surface horizontal.

Also available with Mono sensor element 15 mm, designed to work between 1 MHz and 10 MHz.

Wheelprobe corrosion

The corrosion-wheel sensor has been specifically designed to primarily a plan or circumferential scan. The acceptable minimum diameter of 4 ” (100mm). The adjustment of the probe inspection angle is very quick and can be done just on site using the lever and the guide on the side of the sensor, locking the lever to the desired angle. A longitudinal scan on tube or cylinder is also easy. The minimum diameter for this application is still limited to 4 ” (100mm). For the longitudinal scan, it was necessary to adapt the construction of corrosion-wheel sensor and develop a specific front roller. On tube diameters of less than 24 ” (610mm), this accessory improves stability by supporting the tire. It optimizes the results over a wide range of tube diameters.

Slippery probe

Slippery probe was developed with a molded rubber line delay using the same formula as the tire from the wheel sensor.
