Single Element Transducers

For Use with CL-Series Precision Thickness Gauges

GE Inspection Technologies offers a complete line of Krautkramer single element contact and delay style transducers that are compatible with ultrasonic precision thickness gauges (CL 5 and CL 400).

A wide variety of transducers is available, satisfying virtually any inspection requirement on metals and nonmetals with relatively smooth, parallel surfaces.

Depending on the material conditions and the instrument / transducer combination, measurements are possible from 0.005 to 15.00 inches, (.13 to 381 mm) with resolution down to 0.0001 inches.

Criteria for transducer selection is based on test material, thickness range, curvature, and accessibility of the test area. High frequency delay line transducers provide short pulse lengths for measuring thin materials. Lower frequency contact transducers offer improved penetration, making them a better choice when testing attenuative or coarse grain materials. Contact diameter should be considered to prevent excess couplant from being trapped between the transducer and test surface, or when testing on small radii. Contact us if you need assistance selecting the proper transducer for your application.
