Immersion transducers are specifically designed to test parts partially or wholly immersed in water, which allows a uniform and fast coupling technique for rapid scanning of parts. Focusing lens can be added to increase transducer sensitivity and performance in a particular area of a part. Immersion transducers can be focused either spherically or cylindrically upon request within the allowable focal range for a given frequency and element size.
i-1 and i-2 Style Housings
0.25 inches (6 mm) diameter elements with 0.375 inches (10 mm) housings for difficult to reach fillet or bore areas are available with straight Microdot (I-1) or straight UHF (I-2) connectors and 303 stainless steel housings
