The DAKOTA NDT Dual Element Transducer is a high-performance ultrasonic transducer meticulously engineered for exceptional near-surface resolution in critical thickness gauging and flaw detection applications. Operating at a frequency of 7.5 MHz with a 1/4 inch element diameter, this transducer is specifically designed to provide enhanced detail in the near-surface region of inspected materials.  

The dual element configuration, utilizing separate transmitting and receiving crystals, offers significant advantages. It provides superior near-surface resolution, improved acoustic coupling on challenging surfaces (such as rough or curved materials), and minimizes interference from delay line reflections in certain high-temperature scenarios. The carefully angled elements create a focused ultrasonic beam, optimizing sensitivity for detecting small anomalies.  

This robust model features a potted cable, ensuring a durable and environmentally sealed connection that offers excellent resistance to moisture and dust. The side connector provides a practical and space-efficient cable exit, allowing for flexible routing in confined inspection areas. The transducer is encased in a high wear stainless steel casing with a substantial 1/4 inch thickness, providing exceptional durability and resistance to abrasion in demanding industrial environments, ensuring a long service life even under harsh conditions.

The 7.5 MHz frequency delivers excellent resolution for detecting very small flaws and accurately measuring thin materials. The 1/4 inch element diameter provides a balance between sensitivity and beam coverage, making it suitable for a wide range of inspection tasks requiring high near-surface detail.
