Immersion Transducer 

An immersion transducer is a single element longitudinal wave transducer with a ¼ wavelength layer acoustically matched to water. It is specifically designed to transmit ultrasound in applications where the test part is partially or wholly immersed.

Advantages 

• The immersion technique provides a means of uniform coupling.
• Quarter wavelength matching layer increases sound energy output.
• Corrosion resistant 303 stainless steel case with chrome-plated brass connector.
• Proprietary RF shielded for improved signal-to-noise characteristics in critical applications.
• All immersion transducers, expect paintbrush, can be focused spherically (spot) or cylindrically (line).
• Customer specified focal length concentrates the sound beam to increase sensitivity to small reflectors.  

Applications

• Automated scanning
• On-line thickness gaging
• High speed flaw detection in pipe, bar, tube, plate and other similar components
• Time-of-light and amplitude based imaging
• Through transmission testing
• Material analysis and velocity measuremant

Usage Note: Transducers should not be submerged for periods exceeding 8 hours. Allow 16 hours of dry time to ensure the life of the unit.

Standard Case – Immersion Transducer, 20 MHz, Standard Case Style, Straight UHF.
