Contact transducers are available in frequencies up to 225 MHz. Performance is dependent on pulser/receiver and application. All transducers are manufactured on a special basis to customer specifications. Contact us to discuss applications.

High Frequency Transducers

High frequency transducers are single element contact or immersion transducers designed to produce frequencies of 20 MHz and greater.

Advantages:

Heavily damped broadband design provides excellent time resolution
Short wavelengths for superior flaw resolution capabilities
Focusing allows for very small beam diameters
Frequencies range from 20 MHz to 225 Mhz

High Frequency Contact

Permanent fused silica delay line allows for flaw evaluation, material analysis or thickness measurements using a direct contact testing method
Three different delay line configurations (BA, BB, BC) allow for various combinations of delay line echoes
Standard connector style is Right Angle Microdot^® (RM)

High Frequency Standard Immersion Case

Permanent fused silica delay line
Focused units use an optical quality ground lens
F202 adaptor allows fixturing with a passive UHF connector and an active Microdot^® style connector (see page 38)
Combines high frequency with a small case design

High Frequency SU/RM Immersion Case

Permanent fused silica delay with an optical quality ground lens provides a high degree of precision in beam alignment and focusing
Stainless steel case has a passive Straight UHF (SU) connector and an active Right Angle Microdot (RM) connector
Large cases allow for larger delay lines and decrease in delay reverberations and noise

*Transducers create surface waves in steel, titanium and other materials with similar velocities. Please contact us for higher frequency. Lightweight High Frequency transducers are an alternative to the SU/RM case style transducers. They offer a smaller case width and lighter weight without sacrificing performance.
