NM01T1012000
These high-performance ultrasonic transducers, manufactured by the reputable Dakota Ultrasonics, are specifically designed for precise thickness gauging and flaw detection, particularly in challenging inspection environments.
Featuring a robust dual element configuration, these transducers excel in applications where single element probes might struggle due to surface conditions or material properties.
The dual element design incorporates physically separated transmitting and receiving piezoelectric crystals within a single housing. This unique arrangement provides significant advantages:
Superior Near-Surface Resolution: By isolating the transmitted pulse from the received echoes, these transducers offer exceptional ability to detect and measure features very close to the material surface, crucial for identifying early stages of corrosion or thin layers.
Enhanced Reception of Attenuated Echoes: The separated elements improve sensitivity to weak or scattered ultrasonic signals, making them ideal for inspecting materials with rough surfaces, high attenuation characteristics, or for detecting subtle indications of corrosion like pitting.
Reduced Sensitivity to Lift-Off: Dual element transducers are generally less susceptible to variations in probe coupling or slight lift-off from the inspection surface, contributing to more consistent and reliable readings in demanding field applications.
The key technical specifications of these transducers are:
Center Frequency: 5 MHz: This frequency provides an excellent balance between penetration capability and resolution, making it suitable for a wide range of materials and thicknesses commonly encountered in industrial inspections. It generally provides deeper penetration than higher frequency transducers while still offering reasonable resolution.
Diameter: 3/16 inch (approximately 4.76 mm): The small diameter of the active element area is advantageous for inspections in tight spaces or on highly curved surfaces.
Connector Potted, entry side: This describes the robust connection of the transducer cable to the housing. The connector is "potted," meaning it is encased in a protective material (typically epoxy or similar) on the entry side of the transducer. This provides excellent strain relief for the cable, preventing damage from bending or pulling, and offers environmental protection against moisture and contaminants, crucial for maintaining reliability in diverse conditions.
