Ultrasonic Transducers & Probes


Contact Transducer


Contact Transducer

A contact transducer is a single element longitudinal wave transducer intended for use in direct contact with a test piece.


Dual Element Transducer


Dual Element Transducer

A dual element transducer consists of two crystal elements housed in the same case, separated by an acoustic barrier.


Delay Line Transducers


Delay Line Transducers

A replaceable delay line transducer is a single element Videoscan transducer with a case design configured for use with a replaceable delay line.


Angle Beam Transducers


Angle Beam Transducers

Angle beam transducers are single element transducers used with a wedge to introduce a refracted shear wave or longitudinal wave into a test piece.


Spot Weld Transducers


Spot Weld Transducers

Olympus NDT ultrasonic spot weld transducers are specifically designed to provide optimal performance for nondestructive testing of numerous types of spot welds, including those used in automotive and industrial applications. Ultrasonic inspection of spot welds involves the analysis of what is known as the "ringdown" of sound within

the weld nugget. Unlike many other direct measurement techniques, spot-weld inspection looks at the characteristics of the multiple echoes returned from sound energy ringing within the weld nugget. Echo spacing, sound attenuation, and intermediate echo detection are some of the indicators of weld quality that are analyzed by trained inspectors.

Our transducers have excellent signal-to-noise ratios due to broadband design, which is critical for distinguishing good welds from poor welds. These transducers are available in a multitude of sizes in 0.5 mm increments to ensure that the proper transducers are available for a variety of weld nugget sizes. Element sizes are engraved with both English and metric units for worldwide use. The versatile design of these spot weld transducers allows them to be used with either a soft membrane captive water column or a hard tip delay line. Transducers, delay lines, and water columns are sold separately.


AWS Transducers Wedges

AWS transducers and wedges conform to the specific requirements of the American Welding Society's Structural Welding Code for angle beam assemblies used in weld inspection.


CDS Wedges


CDS Wedges

CDS wedges are designed to generate both a 30 degree shear wave and a 70 degree longitudinal wave in steel for sizing ID connected cracking by means of the 30-70-70 technique.


Normal Incidence Shear Wave


Normal Incidence Shear Wave

Single element normal incidence Shear Wave Transducers contact transducers introduce shear waves directly into the test piece without the use of refracted wave mode conversion. We recommend the use of our SWC shear wave couplant for general purpose testing.


Standard Angle Beam


Standard Angle Beam

Standard angle beam transducers are large single element transducers used with a wedge to introduce a refracted shear wave or longitudinal wave into a test piece.


Integral Angle Beam


Integral Angle Beam

Integral angle beam transducers provide superior signal-to-noise characteristics and contain durable plastic wear. Both Right Microdot and Straight Microdot connectors are available on some styles.


Protected Face Transducers


Protected Face Transducers

A protected face transducer is a single element longitudinal wave contact transducer that can be used with either a delay line, protective membrane, or protective wear cap.


Immersion Transducers


Immersion Transducers

An immersion transducer is a single element longitudinal wave transducer with a 1/4 wavelength layer acoustically matched to water. Immersion transducers are specifically designed to transmit ultrasound in applications where the test parts are partially or wholly immersed in water, which allows a uniform and fast coupling technique for rapid scanning of parts. Focusing lens can be added to increase transducer sensitivity and performance in a particular area of a part. Immersion transducers can be focused either spherically or cylindrically upon request within the allowable focal range for a given frequency and element size.


TOFD Transducers & Wedges


TOFD Transducers & Wedges

TOFD transducers and wedges generate refracted longitudinal waves in steel for use in applications involving crack sizing by means of the Time of Flight Diffraction technique.


High Frequency Transducers



High Frequency Transducers

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


Atlas European Standard Transducers

Atlas European Standard Transducers

Atlas European Standard Transducers feature LEMO connectors, metric unit element diameters, and common frequencies, such as 1, 2, and 4 MHz. They are designed to meet inspection criteria referenced throughout Europe and the rest of the world.


EMAT Transducers


EMAT Transducers

Electromagnetic Acoustic Transducers are single element transducers that employ a magnetostrictive effect to transmit and receive ultrasonic waves.
Part number is E110-SB.


RTD


RTD

RTD Transducers are well known in the nuclear industry for inspection of critical weld areas in pipes and pressure vessels. We are the exclusive North American Representative for this special line of transducers manufactured by RTD in the Netherlands. The realm of applications for these transducers is extensive: inspection of coarse grain austenitic steel, location of undercladding cracks, detection and sizing of IGSCC, automated scanning of pipe and pressure vessels, and continuous high temperature applications.


Test Blocks


Test Blocks

Calibration and/or Reference Blocks should be used in every application. Standard blocks are available for angle beam calibrations and thickness calibrations of common materials.

Blocks manufactured from 1018 steel, 304 stainless steel, or 7075-T6 aluminum are commonly in stock
(other materials require special quotes for price and delivery).
