NM01TWS250MT

The OKO-NDT Angle Beam Probe TWS is a single-element ultrasonic transducer designed for angle beam inspection using the shear wave technique. This probe has a center frequency of 2 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 flaws that are not oriented parallel to the inspection surface.

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: 2 MHz: The 2 MHz frequency offers a balance between penetration depth and resolution. It provides good penetration in many common industrial materials while still being sensitive to moderately sized flaws.

• 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. A larger element generally provides a more focused beam in the far field.

• 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.

• 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.

Applications:

• Weld inspection to detect and characterize discontinuities such as cracks, lack of fusion, and slag inclusions.

• Inspection of pipes, tubes, forgings, and castings for subsurface flaws.

• Detection of stress corrosion cracking.

• General angle beam ultrasonic testing in various industries, including oil and gas, aerospace, and manufacturing.

Importance:

• Enables Angle Beam Testing: Essential for inspections requiring the introduction of an angled sound beam to detect flaws with specific orientations.

• Versatile Frequency and Size: The 2 MHz frequency and 0.50" element size offer a good balance for a wide range of applications and material thicknesses.

• Reliable Manufacturer: OKO-NDT is a recognized name in the NDT industry, assuring a quality product.
