The OKO-NDT Angle Beam Probe (Single Element) is a high-quality ultrasonic transducer designed for performing angled beam inspections in a variety of non-destructive testing (NDT) applications. This specific probe features a center frequency of 4.0 MHz, offering a balance between penetration capability and sensitivity to smaller discontinuities. The design provides a nominal refracted shear wave angle of 45 degrees within the test material (typically steel, when used with an appropriate wedge), making it well-suited for detecting flaws that are not oriented perpendicular to the inspection surface, such as those commonly found in welds.

The active element of the transducer measures 14 x 14 mm, a size that contributes to the shape and focusing characteristics of the ultrasonic beam, generally providing a well-defined beam profile in the near and far fields. This element is housed in a durable casing and is equipped with a standard Lemo 00 connector, ensuring secure and reliable electrical connection to a wide range of ultrasonic flaw detectors and instrumentation.

Manufactured by OKO-NDT, a reputable provider of NDT equipment, this angle beam probe is engineered for consistent performance and durability in demanding inspection environments. It is a crucial component in various UT techniques, including:

• Weld inspection: Detecting and characterizing defects like cracks, lack of fusion, and porosity within weldments. The 45-degree angle is a widely used standard for weld examination.

• Crack detection and sizing: Identifying and evaluating the dimensions of cracks in various metallic and composite materials.

• Corrosion mapping and assessment: Although primarily designed for flaw detection, angle beam techniques can sometimes be employed to assess the extent of corrosion in certain configurations.

• General volumetric inspection: Examining the internal integrity of components for hidden flaws and discontinuities.

Note: This is a single element probe and requires the use of an appropriate angle beam wedge (not included) to introduce the ultrasonic beam into the test material at the specified 45-degree angle. The selection of the wedge material and its geometry is critical to achieving the desired refracted angle and optimal coupling of the ultrasonic energy into the test piece.

In summary, the OKO-NDT Angle Beam Probe (Single Element), 4.0 MHz, 45°, 14 x 14 mm with a Lemo 00 connector, is a reliable and effective transducer for a wide range of angle beam ultrasonic testing applications, providing a good balance of sensitivity, penetration, and beam characteristics for accurate flaw detection and evaluation.
