Dakota Immersion Transducers are designed for ultrasonic inspection in immersion tank or bubbler systems, where the transducer and the part are coupled through water rather than placed in direct contact. Immersion testing gives consistent, repeatable coupling and is used where surface contact would be unreliable or where parts are scanned automatically through a water path.

Each Dakota Immersion Transducer has a stainless steel housing with a UHF connector and is offered in three lens configurations: flat, spherical focus and cylindrical focus. Spherical and cylindrical focusing concentrate the sound beam, which improves resolution and sensitivity for the geometry being inspected.

The range of the Dakota Immersion Transducers covers frequencies from 1.00MHz to 15.00MHz and probe diameters from 1/4 inch to 1 inch, with damping options identified by code including HG (high gain), H (highly damped) and R (resolution), plus composite (S) construction at 1.00MHz. Part numbers are matched to Dakota flaw detector instruments such as the FX70, FX71, FX80 and FX81. The wide choice of frequency, diameter, lens type and damping allows the Dakota Immersion Transducer to be matched to the material, thickness range and resolution required.
