Panametrics-NDT Ultrasonic Transducers

Olympus NDT ultrasonic spotweld transducers are specifically designed to provide optimal performance for nondestructive testing of numerous types of spotwelds, including those used in automotive and industrial applications. Ultrasonic inspection of spotwelds involves the analysis of what is known as the "ringdown" of sound within the weld nugget. Unlike many other direct measurement techniques, spotweld 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.

PANAMETRICS-NDT™

Our new Panametrics-NDT 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 spotweld transducers allows them to be used with either a soft membrane captive water column or a hard tip delay line. Panametrics-NDT transducers, delay lines, and water columns are sold separately.

HARISONIC®

Olympus NDT also offers a series of PVDF (polymer) transducers from the Harisonic line specifically for use with custom captive water column systems. These polymer transducers are very high resolution transducers due to the very broad bandwidth of the PVDF elements. These Harisonic probes are only for use with captive water columns, which come standard with the purchase of the transducer.

PANAMETRICS-NDT™

Select either delay line or water column  (Transducers, delay lines, delay line retaining rings, water columns, and membranes need to be ordered separately).

Captive Water Column Membranes (Includes O-Rings)

Harisonic®

Purchase of transducer includes water column, one O-ring, and one membrane.

Purchase of additional membranes is recommended.
