The Dakota NDT 2.25 MHz Dual Element Transducer (1/4", Hi Damped, Hi Temp 650°F, Potted, Top Entry) is a specialized and robust probe engineered for precise ultrasonic thickness gauging in challenging high-temperature industrial environments. This transducer combines several critical features to deliver accurate and reliable measurements on hot surfaces, particularly in applications where standard transducers would be unsuitable.

Operating at a 2.25 MHz frequency, this transducer provides a good balance between penetration and resolution, making it suitable for a wide range of materials, including common metals like steel, cast iron, and aluminum. The 1/4 inch (0.250") diameter element offers a versatile acoustic footprint for various applications.

A key distinguishing feature is its "Hi Temp 650°F (343°C)" capability, allowing for direct measurements on surfaces heated up to 650 degrees Fahrenheit. This is crucial for industries such as power generation, petrochemical, and manufacturing, where components often operate at elevated temperatures and cannot be shut down or cooled for inspection. The "Hi Damped" (HD) characteristic ensures a clean ultrasonic pulse with minimal ringing, which significantly improves near-surface resolution and facilitates accurate measurements, even through paint or coatings (when paired with a compatible gauge's Echo-Echo mode).

The dual element design incorporates separate transmitting and receiving crystals, optimizing signal strength and near-surface focusing for reliable and consistent measurements on rough or corroded surfaces. The transducer is potted, meaning its internal components are encased in a durable, high-temperature-resistant material, providing superior protection against thermal stress and environmental factors. The top cable entry offers a common and often preferred cable orientation for many inspection setups.
