Dual Element Transducer, 7.5 MHz, 1/8" , Extra Resolution, Potted, Side, High Wear Stainless Steel Casing, Dakota NDT
The DAKOTA NDT Dual Element Transducer is a high-performance ultrasonic transducer engineered for exceptional near-surface resolution in precision thickness gauging and flaw detection applications. This transducer operates at a frequency of 7.5 MHz with a compact 1/8 inch element diameter, making it ideally suited for detailed examinations of thin materials and detection of minute discontinuities.
The dual element design features separate transmitting and receiving crystals, providing significant advantages such as enhanced near-surface resolution, improved coupling on rough or curved surfaces, and reduced interference from delay line effects in certain high-temperature scenarios. The focused ultrasonic beam generated by the angled elements optimizes sensitivity within the inspection zone.
This specific model is potted with a permanently attached and sealed cable, offering a robust and environmentally protected connection that resists moisture and dust ingress. The side connector provides a convenient and space-saving cable exit, allowing for flexible routing in confined areas. The transducer is encased in a high wear stainless steel casing, ensuring exceptional durability and resistance to abrasion in demanding industrial environments.
The 7.5 MHz frequency delivers superior resolution for detecting very small flaws and accurately measuring thin materials. The 1/8 inch element size further enhances resolution and sensitivity to small anomalies by focusing the ultrasonic beam. This combination makes it an excellent choice for critical inspections requiring high detail in the near-surface region.
