Olympus Double Crystal Thickness Gauge Corrosion Probe, Compatible with Thickness Gauges and Ultrasonic Inspection Equipment

Biaxial probe

Two crystals placed at an angle to each other can create a V-shaped sound path within the material being tested. This "pseudo-focusing" enhances the resolution of the focal area. The two crystals of the dual crystal probe are mounted within a single housing, separated by a sound-insulating barrier. One crystal emits longitudinal waves, while the other acts as a receiver to capture the echoes.

Advantages:

• Enhanced near-surface resolution

• Eliminated the need for double delay blocks in high-temperature applications

• Excellent coupling effect on rough or curved surfaces

• Reduced direct backscatter noise in coarse-grained or scattering materials

• Combined with the penetration ability of low-frequency single crystal probes and the near-surface resolution of high-frequency single crystal probes

• Can be tightly adhered to curved workpieces

Application:

• Remaining Wall Thickness Measurement

• Corrosion/Erosion Monitoring

• Weld Seam Cover and Surfacing Coating Adhesion/Peeling Detection

• Detect porosity, inclusions, cracks, and delamination in castings and forgings.

• Inspect cracks in bolts or other cylindrical components

• Probes with frequencies equal to or less than 5.0 MHz can withstand temperatures up to 425°C; probes with frequencies of 7.5 MHz and 10 MHz can withstand temperatures up to 175°C. For workpieces with surface temperatures ranging from 90°C to 425°C, it is recommended to have a working cycle of no more than 10 seconds of contact, followed by at least 1 minute of cooling in air (not applicable to microtip crystal probes).

Dual crystal probe with identical head shell

• Metal wear-resistant ring extends the probe's lifespan.

• When surface treatment is required on the probe face, provide wear indication reference information

• Roll grooved, 303 stainless steel housing

• Design for replaceable cables (special dual cables with stress relief devices available)

Fingertip dual crystal probe

• Grooved shell, excluding 6mm chip size
  

• 1.8-meter high-tensile flexible密封cable (suitable for BNC or large LEMO 1 connectors)

Extended Range Double Crystal Probe

• This probe's shallow roof corner offers enhanced sensitivity for detecting deeper defects, such as those at a depth of 19mm or more in steel materials, as well as the bottom surface and other reflective bodies.

• In the absence of delay blocks, suitable for high-temperature measurement

• 1.8-meter high-tensile flexible sealing cable with BNC connector
