SIGMA Immersion Transducers are designed to provide wide use in scanning systems, whether manual, or automatic. Immersion Transducers are ideal where a part can be immersed, since a liquid separation between the transducer and the part to be inspected allows excellent conformity and front surface resolution. In addition, the liquid path enables the user to bracket the inspection zone in the part between front surface liquid multiples, and manipulate the Transducer to allow a full range of inspection angles.
SIGMA Immersion Transducers are available in four standard types:

MINIATURE-.38 inches in diameter X 1.45" long

  • ELEMENT SIZE-.125 to .25 inch diameter
  • FREQUENCY-1.0 to 15MHz
  • CONNECTOR-Lemo 01 or Microdot

    ISS-.63 inches diameter X 2.0" long

  • ELEMENT SIZE-.25 to .50 inches in diameter
  • FREQUENCY-1.0 to 15MHz
  • CONNECTOR-UHF

    LARGE-element size dependant

  • ELEMENT SIZE- .75 inch diameter and up
  • FREQUENCY- element size dependant
  • CONNECTOR- UHF

    For general higher temperature use, see High Temperature Transducers.

All SIGMA Immersion Transducers are available as focused units, either spherical or cylindrical, by lens or by ground element, (ground element is limited to 10MHz). Focusing is limited by Near Field distance.

To order please call SIGMA or define the unit according to the following guideline.
