An immersion transducer is a single element longitudinal wave transducer with a 1/4 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 connectors
• Proprietary RF shielding for improved signal-to-noise characteristics in critical applications
• All immersion transducers, except paintbrush, can be focused spherically (spot) or cylindrically (line) (see Technical Notes page 45)
• 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-flight and amplitude based imaging
• Through transmission testing
• Material analysis and velocity measurements

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

• Knurled case with Straight UHF connect or (SU)
• Contact us for nonknurled case design and availability of other connector styles
• Frequencies ranging from 1.0 to 25 Mhz

Side Looking Immersion Transducers

• Ideal for measuring wall thicknesses of pipe where access to the outer diameter is limited
• Small outer diameter allows for greater accessibility in tight spaces than standard immersion transducers with reflector mirrors
• Sound exit point is located at a 90° angle relative to the straight Microdot ^® connector
• Probe extensions such as the F211 are available to lengthen the standard design

Extra Miniature (XMS) Transducer

The XMS transducer is an extremely small 10 MHz immersion transducer with a 3 mm (0.118") diameter by 3 mm (0.118") long case. This transducer is ideal for extremely tight access areas or for multi-element array flaw detection. The transducer assembly has a special connector attached to the 1 m (38") long potted cable. An adaptor is also available to interface with most commercial ultrasonic equipment.
