Immersion Transducers are specifically designed to operate in an immersion tank or with bubbler/squirter systems. They are usually manufactured with UHF waterproof connectors and can be designed with flat or focused lenses. All Immersion transducers are offered in High Resolution (HR), General Purpose (GP), or High Power (HP).
Immersion Transducers have several advantages over contact-type transducers. First, their uniform coupling reduces variations in sensitivity. Second, Immersion transducers offer increased speed from the ability to perform automated scanning. Third, the focusing of Immersion Transducers increases the sensitivity to small defects. Immersion transducers are available in unfocused, spherically focused, and cylindrically focused configurations. An unfocused Immersion Transducer is used for general applications in the measurement of thick materials. A spherically focused transducer will improve the sensitivity to small flaws and defects. A cylindrically focused transducer is typically used in the measurement of tubing raw stock. The range of focal lengths for a spherical or cylindrical transducer is limited to the transducer's near field and is generally a maximum of 0.8N.
- Immersion Transducers speed up test results with high speed scanning of large surfaces
- Spherical focusing available for minimizing beamwidth for sensitivity to smaller defects
- Epoxy quarter wavelength matching layer maximizes sensitivity and resolution
- Cylindrical focusing available for tube or bar inspection
