NM01PXCDTOF202

The Sonatest 2MHz TOFD 6mm Diameter Lemo 00 Transducer is a specialized ultrasonic probe designed for Time-of-Flight Diffraction (TOFD) applications. This transducer is optimized to generate and receive ultrasonic waves that diffract off the tips of flaws, providing highly accurate sizing and location of defects in materials, particularly in welds.

Key Features & Benefits:

• TOFD Optimization: This transducer is specifically engineered for the TOFD technique. It typically produces a broad, well-defined longitudinal wave beam with minimal ringing, which is crucial for capturing the diffracted signals that characterize TOFD.

• 2 MHz Frequency: The 2 MHz operating frequency is ideal for inspecting thicker sections of material (e.g., steel welds with thicknesses over 15−20mm). It offers excellent penetration through coarse-grained or attenuating materials while still providing sufficient resolution for defect sizing.

• 6mm (0.236") Element Diameter: The 6mm crystal diameter provides a good balance between beam spread and acoustic energy. For TOFD, a wider beam (achieved with smaller diameter elements at lower frequencies) is often desirable to ensure the entire flaw is ensonified, while still maintaining acceptable sensitivity.

• Lemo 00 Connector: Equipped with a Lemo 00 (size 00) coaxial connector, this transducer ensures a secure, reliable, and low-noise connection to compatible ultrasonic flaw detectors (e.g., Sonatest Veo+, Prisma, Sitescan series) and TOFD cables. Lemo 00 is a miniature, push-pull self-latching connector widely used in NDT.

• De-mountable Design: Sonatest TOFD transducers, including this model (e.g., from the CDTOF or DTOF series), are designed to be "de-mountable." This means they screw directly into compatible TOFD wedges (like the ST Steel TOFD Wedge M12 previously described) via an M12 thread. This allows for easy interchangeability of transducers, simplifying setup and reducing the need for multiple fixed-probe wedges.

• Robust Construction: Encased in a durable housing (often stainless steel), these transducers are built to withstand the rigors of industrial NDT environments. They typically feature a wear-resistant face (e.g., ceramic) to maximize service life.

• High Sensitivity and Signal-to-Noise Ratio: Crucial for detecting faint diffracted signals from small flaws, leading to more reliable inspection results.

• Sonatest Quality: Manufactured by Sonatest, a global leader in NDT equipment, ensuring high quality, consistent acoustic performance, and full compatibility within the Sonatest ultrasonic ecosystem.

Typical Applications:

• Weld Inspection: Primary application for precise detection and sizing of defects such as cracks (fatigue, hydrogen-induced, stress corrosion), lack of fusion, and volumetric flaws in various weld configurations (butt welds, T-joints).

• Crack Sizing: Highly effective for measuring the height and through-wall extent of cracks, a critical parameter for fitness-for-service assessments.

• Pressure Vessels and Piping: Ideal for inspecting thicker sections in the oil & gas, petrochemical, and power generation industries.

• Heavy Fabrication: Used in the inspection of large steel structures, bridges, and other heavy industrial components.

• Post-Weld Heat Treatment (PWHT) Crack Detection: Can be used to find cracks that may form after welding processes.
