The Sonatest 10 MHz 3mm TOFD Probe M12 Lemo 00 "10 MHz 3mm ONLY" is a high-frequency, small-diameter ultrasonic transducer specifically engineered for Time-of-Flight Diffraction (TOFD) applications. This probe is designed to provide high resolution and precision in detecting and sizing very small flaws, particularly in thinner materials where fine detail is critical.

Key Features & Benefits:

• High Frequency (10 MHz): The 10 MHz operating frequency provides excellent resolution, allowing for the detection and precise sizing of very small and tightly closed discontinuities. This frequency is ideal for inspecting thin-walled components and materials where high-detail flaw characterization is essential.

• Small Element Diameter (3mm): The 3mm (0.118") crystal diameter generates a more focused ultrasonic beam. In TOFD, while broader beams are often used for general coverage, a smaller element can provide enhanced resolution for specific, intricate flaw tip detection, especially when paired with a precise scanning setup.

• TOFD Optimization: This probe is specifically designed for the TOFD technique, producing a well-controlled ultrasonic beam (typically a longitudinal wave) that efficiently diffracts off the tips of flaws, enabling accurate height and through-wall sizing.

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

• M12 Thread: The transducer features an M12 male thread, allowing it to be easily mounted and de-mounted from compatible TOFD wedges (such as Sonatest's WTOF-SSI series, e.g., an ST Steel TOFD Wedge M12, 60° or 70° for thinner sections). This interchangeable design offers flexibility in adapting the probe to different wedge angles and simplifies replacement.

• Robust Construction: Encased in a durable housing (typically stainless steel), this transducer is built to withstand the demanding conditions of industrial NDT environments. It usually features a wear-resistant face (e.g., ceramic or polymer) to maximize service life.

• High Signal-to-Noise Ratio: Despite its high frequency and small size, the probe is engineered to deliver a strong signal from diffracting tips, which is crucial for distinguishing flaw signals from background noise in TOFD data.

• Sonatest Quality: Manufactured by Sonatest, a globally recognized leader in Non-Destructive Testing (NDT) equipment, ensuring high quality, consistent acoustic performance, and full compatibility within the Sonatest ultrasonic ecosystem.
