Dual-Element Ultrasonic
Coating Thickness Transducers
By StressTel

Two angled ultrasonic elements function as a transmitter and receiver
for better signal-to-noise ratio than single-element transducers.

SressTel’s superior quality general thickness and corrosion transducers are a key element in any ultrasonic testing procedure.

StressTel’s dual-element transducers will assure the most accurate test results in your measurement applications.

All StressTel transducers are manufactured in an ISO 9001 facility.

Dual-element transducers are designed for optimum performance with all StressTel thickness gauges as well as other compatible gauges and flaw detectors. They are longitudinal transducers with two separate elements that are angled toward each other, thereby focusing the sound beam. The two elements function as a transmitter and receiver, thus producing a better signal-to-noise ratio than can be achieved with single element transducers.
Dual-element transducers are particularly suited for thin range thickness gauging and flaw detection. They are designed for detection of near surface discontinuities and corrosion. The transducers are color coded for easy identification and have a knurled case for positive gripping.
