The OKO-NDT Angle Beam Probe TWS is a single-element ultrasonic transducer designed for high-resolution angle beam inspection using the shear wave technique. This probe features a center frequency of 5 MHz and an active element size of 0.50 inches (12.7 mm). It is intended for use with an appropriate wedge to introduce a refracted shear wave into the test material at a specific angle, enabling the detection and characterization of smaller flaws and providing enhanced resolution compared to lower frequency probes.
Key Features:
Single Element Transducer: This probe features a single piezoelectric crystal element, which both transmits and receives ultrasonic energy.
Angle Beam Inspection: Designed specifically for angle beam testing, requiring the use of a wedge to create a refracted wave (typically shear wave) in the material under examination.
Center Frequency: 5 MHz: The higher 5 MHz frequency provides improved resolution and sensitivity to smaller discontinuities compared to lower frequency probes. However, it may have a trade-off in terms of penetration depth in highly attenuating materials.
Element Size: 0.50" (12.7 mm): The 0.50-inch diameter or dimension of the active element influences the beam characteristics, such as beam spread and focusing capabilities. This size offers a good balance for many angle beam applications.
TWS Series: The "TWS" designation likely refers to a specific series or design within OKO-NDT's line of angle beam transducers, potentially indicating features like compact size, specific connector type, or optimized performance characteristics for near-surface resolution or specific applications.
OKO-NDT Manufacturing: Manufactured by OKO-NDT Group, a reputable company specializing in non-destructive testing equipment and accessories, ensuring quality and reliability.
Shear Wave Technique: Primarily used to generate shear waves in the test material when coupled with an appropriate angle beam wedge. Shear waves are highly effective for detecting cracks, lack of fusion, and other planar defects. The higher frequency enhances the ability to detect smaller imperfections.
Applications:
High-resolution weld inspection to detect and characterize small discontinuities such as micro-cracks, lack of fusion, and small inclusions.
Inspection of thinner materials where higher resolution is beneficial.
Detection of stress corrosion cracking and fatigue cracks.
Detailed flaw characterization and sizing in various materials, including metals, composites, and some plastics.
General angle beam ultrasonic testing in industries where high sensitivity is paramount, such as aerospace and precision manufacturing.
Importance:
Enables High-Resolution Angle Beam Testing: Essential for inspections requiring the detection of very small flaws and detailed flaw characterization using an angled sound beam.
Improved Sensitivity: The higher frequency enhances the probe's ability to detect smaller discontinuities.
Versatile Size: The 0.50" element size is suitable for a range of angle beam applications.
Reliable Manufacturer: OKO-NDT is a recognized name in the NDT industry, assuring a quality product.
