Sonatest QCG and PQC Quick Change Transducers

Sonatest QCG and PQC Quick Change Transducers

Single Crystal Transducers for use with Quick Change Wedges

Overview

The Sonatest QCG and PCG Transducers are designed for to be used with replaceable QC style wedges. The QCG is medium damped and features lead metaniobate crystal; the PCG is high damped with a composite crystal. These Angle Beam transducers are ideal for inspection of welds, tubes, piping, and forgings. The wedges are sold separately. 

Features

  • Angle Beam with replaceable wedges
  • QCG medium damped lead metaniobate crystal with medium bandwidth
  • PQC high damped composite crystal with wide band width
  • Max operating temperature 50°C / 120°F
  • Microdot Connector Standard; Subvis can be supplied on special order
  • Wedge angles are based on the velocity of steel unless another material is specified
  • High temperature options available up to 285°C / 545°F
  • Wedge angles are based on the velocity of steel unless another material is specified
  • Wedges can be machined for use on curved material in either lateral or circumferential direction and either I.D. or O.D.
  • Wedges are available for shear edge; refracted longitudinal angles are available upon request

Applications

QCG and PQC Transducers are generally used for inspections in the fabrication industry. Designs for higher temperature applications increase the QCG and PQC's scope of application. 

Common applications include:

  • General Welds
  • Tube and Pipe Inspection
  • Forgings
