NM01TSB525

The OKO-NDT Straight Beam Probe TSB (Single Element), 5 MHz, 0.250" with Regular Connector is a high-frequency, small-diameter ultrasonic transducer designed for precision conventional ultrasonic testing (UT). It is particularly well-suited for applications requiring high resolution to detect small defects, especially in thinner materials, or for highly accurate thickness measurements.

Key Features & Benefits:

• Straight Beam Inspection (Normal Incidence): This probe transmits longitudinal ultrasonic waves perpendicularly into the test material. This makes it highly effective for detecting defects such as laminations, inclusions, porosity, and cracks that are oriented parallel to the inspection surface. It is also excellent for precise thickness gauging.

• Single Element Design: Operating in pulse-echo mode, this probe uses a single piezoelectric crystal for both transmitting and receiving ultrasonic signals. This standard configuration provides reliable and clear signal interpretation on conventional ultrasonic flaw detectors.

• 5 MHz Frequency: This high operating frequency provides excellent resolution, allowing for the detection and precise characterization of very small discontinuities. It is ideal for inspecting thinner sections of material and materials with fine grain structures, where higher resolution is beneficial for identifying subtle flaws.

• 0.250" (6.35 mm) Element Diameter: The small 0.250-inch (6.35 mm) active element produces a well-defined and focused acoustic beam. This compact size makes it suitable for inspecting areas with limited access and provides excellent near-surface resolution, which is crucial for detecting flaws close to the material surface.

• "Regular" Connector (Typically BNC): While "Regular" can sometimes be ambiguous, for OKO-NDT and similar manufacturers, this typically refers to a standard BNC (Bayonet Neill-Concelman) coaxial connector. BNC connectors are widely used in NDT for their secure, quick-connect/disconnect mechanism and broad compatibility with most conventional ultrasonic flaw detectors and cables. The connector is usually located at the top or end of the probe body.

• Robust Construction: Manufactured by OKO-NDT (part of the OKOndt GROUP), this probe features a durable housing (often stainless steel or plated brass) and a wear-resistant face. This robust design ensures longevity and consistent performance in demanding industrial environments.

• Versatile Application: Despite its higher frequency and smaller size, it remains versatile for a range of applications, especially where high resolution on thin sections is paramount.
