The OKO-NDT Angle Beam Probe (Single Element) with a 60° nominal refracted angle is a precision-engineered ultrasonic transducer specifically designed for performing angled beam inspections in a diverse range of non-destructive testing (NDT) applications. This probe operates at a center frequency of 4.0 MHz, a frequency that provides an excellent compromise between the ability to penetrate through various materials and the sensitivity required to detect moderately sized to small imperfections. The key feature of this transducer is its 60-degree nominal refracted shear wave angle when the ultrasonic beam enters the test material (typically calibrated for steel when used with an appropriate wedge). This steeper angle of incidence is strategically chosen for specific inspection scenarios where it offers advantages over shallower angles like 45 degrees.
The active piezoelectric element within the probe has dimensions of 14 x 14 mm. This element size plays a crucial role in shaping the ultrasonic beam characteristics, influencing factors such as beam spread and sensitivity across the inspection range. The probe is equipped with a standardized Lemo 00 connector, ensuring secure and electrically sound connections to a wide variety of industry-standard ultrasonic flaw detectors and testing instruments.
As a product of OKO-NDT, a recognized manufacturer in the field of non-destructive testing equipment, this angle beam probe is built to meet the demands of rigorous inspection tasks, offering reliable performance and durability. The 60-degree refracted angle makes this probe particularly well-suited for applications such as:
Enhanced detection of vertically oriented or near-vertical flaws: The steeper angle allows for better reflection of ultrasonic energy from discontinuities with this orientation, which might be less effectively detected with shallower angles.
Inspection of thinner materials or components with complex geometries: The 60-degree angle can be advantageous in situations where a shallower angle might lead to unwanted reflections or mode conversions.
Circumferential weld inspection on pipes and other cylindrical structures: This angle is frequently employed for examining welds that run around the circumference of a component.
General flaw detection in various materials: It provides an alternative inspection angle to increase the probability of detection for differently oriented defects.
Important Note: Like all angle beam transducers, this probe necessitates the use of a specifically designed angle beam wedge (couplant block), which is not included with the probe itself. The wedge is crucial for introducing the ultrasonic beam into the test material at the desired 60-degree refracted angle. The selection of the appropriate wedge material and angle is essential and depends on the material being inspected and the desired refracted angle within that material.
In summary, the OKO-NDT Angle Beam Probe (Single Element) with a 4.0 MHz frequency, a 60° nominal refracted angle, a 14 x 14 mm element, and a Lemo 00 connector is a valuable and versatile tool for ultrasonic testing professionals. Its specific angle makes it highly effective for a range of flaw detection applications, particularly those involving vertically oriented defects and certain geometric constraints, contributing to thorough and reliable non-destructive evaluations.
