产品简介
An immersion transducer is a single element longitudinal wave transducer with a 1/4 wavelength layer acoustically matched to water. Immersion transducers are specifically designed to transmit ultrasound in applications where the test parts are 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.

概览

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.
