This Dakota Ultrasonics Finger Tip Single Element Contact Transducer (FC) is a highly practical and compact ultrasonic transducer designed for direct contact inspections, particularly in situations where access is limited or the test surface is complex. Its finger-tip style housing provides exceptional maneuverability, allowing technicians to easily apply the transducer to curved surfaces, tight corners, and intricately shaped components where larger transducers would be impractical.

Featuring a single active piezoelectric element with a diameter of 1/2 inch, this transducer operates at a nominal frequency of 2.25 MHz. This frequency is a strategic choice, offering a favorable balance between penetration capability in various materials and adequate resolution for detecting subsurface flaws. Compared to higher frequency transducers, the 2.25 MHz frequency allows the ultrasonic waves to travel further through materials that tend to attenuate sound, making it suitable for inspecting thicker sections or more absorptive materials.

As a single element contact transducer, it necessitates direct physical contact with the test object and requires the use of an ultrasonic couplant (such as gel, liquid, or paste) to ensure efficient transmission of the ultrasonic energy into the material. The focused design and moderate frequency make it a versatile tool for a range of general-purpose ultrasonic inspection tasks, particularly where accessibility and penetration are important considerations.

Manufactured by Dakota Ultrasonics, a trusted name in the non-destructive testing (NDT) industry, this finger-tip contact transducer is a valuable asset for NDT professionals across various sectors. Its design prioritizes ease of use and the ability to perform effective ultrasonic inspections in challenging environments where access and a balance of penetration and resolution are key requirements.
