The Dakota NDT Single Element Contact Transducer with a High Wear (HW) face, 1/2" (12.7 mm) diameter, and 1 MHz frequency is a robust and versatile ultrasonic transducer designed for demanding industrial applications in Non-Destructive Testing (NDT). Manufactured by Dakota NDT (formerly Dakota Ultrasonics), a well-regarded name in ultrasonic testing equipment, this transducer is ideal for reliable thickness gauging and flaw detection, especially on surfaces that may cause significant wear to standard probes.

Single element contact transducers utilize a single crystal to both transmit and receive ultrasonic sound waves. The 1 MHz frequency offers excellent penetration capabilities, making it suitable for inspecting thicker or more attenuative materials like cast iron, plastics (polypropylene, polyethylene), and fiberglass. The durable "High Wear" face ensures an extended service life even when coupled with rough, abrasive, or corroded surfaces, providing stability and consistent coupling.

Key Features & Benefits:

• Single Element Design: Utilizes one crystal for pulse-echo measurements, ideal for general-purpose thickness gauging and flaw detection.

• High Wear Face: Equipped with a specially designed, durable wear face that resists abrasion and extends the transducer's lifespan when used on rough or challenging surfaces.

• 1/2" (12.7 mm) Diameter: Provides a good balance of contact area for stable coupling and sound beam spread.

• 1 MHz Frequency: Offers excellent penetration for inspecting:

  • Thick materials.

  • Materials with high attenuation (e.g., cast iron, coarse-grain materials).

  • Various plastics (polypropylene, polyethylene, fiberglass).

  • Rough or corroded surfaces.

• Damping: Typically features medium damping for good signal resolution and penetration balance. (Note: Some 1MHz models may have no damping or composite options).

• Robust Construction: Built to withstand demanding inspection environments.

• Connector Type: Commonly available with Side BNC or Top/Side Microdot/Lemo 00 connectors. (Specific connector type should be verified upon ordering).

• Versatile Applications: Suitable for a wide range of ultrasonic testing instruments, including thickness gauges and flaw detectors.

Technical Specifications (Approximate):

• Transducer Type: Single Element Contact

• Wear Face Type: High Wear (HW)

• Crystal Diameter: 1/2" (12.7 mm)

• Frequency: 1.0 MHz

• Housing Material: Stainless steel with extended wear ring.

• Damping: Medium (or "None" depending on specific model variant)

• Connector: Side BNC, or Microdot/Lemo (specify upon order)

• Range (in Steel): Typically suited for thicker materials, ranges vary by specific gauge and application (e.g., 0.150" to 2.0" for thickness gauges).

• Wearface Diameter: Approximately 5/8" (15.9 mm) (larger than crystal diameter due to wear face).

Applications:

• Thickness Gauging: Especially on rough, corroded, or heavily coated surfaces.

• Flaw Detection: Identifying internal defects in thicker materials.

• Corrosion Surveys: Assessing wall thickness in pipelines, tanks, and pressure vessels.

• Castings and Forgings: Inspecting for internal discontinuities.

• Materials Inspection: Ideal for cast iron, composites, and various plastics.

• General Purpose UT: Where robust performance and penetration are key.
