In-House Built Transducers for Ultrasonic In-Line Inspection

Transducers are the eyes of an ultrasonic in-line inspection tool, allowing inspectors to see into the structure of a pipeline. 

The electronics store data, the cups and body propel the tool, and the software turns signals into reports, but without sharp eyes, none of that matters. Transducers provide insight into the integrity of a pipe by transmitting and receiving ultrasonic signals, converting reflected mechanical waves from the pipe wall into electrical signals. 

Those signals become precise measurements of corrosion, pitting, and cracking. If the transducers are weak, so is the data. 

Not all transducers are created equal. 

Small design and manufacturing variations can have a major impact on performance, affecting resolution, signal-to-noise ratio, sensitivity, durability, and long-term calibration stability.  

When measurements are resolved in microseconds and fractions of a millimeter, those details matter. 

That is why Dexon builds its ultrasonic transducers entirely in-house – from housing and assembly to testing and validation. Off-the-shelf components rarely meet the extreme demands of high-resolution crack and metal loss inspection. They also slow development, increase cost, and introduce supply-chain risk. 

With in-house production, Dexon’s engineers can: 

• Tune transducers for specific tool designs and applications  

• Hold tighter acoustic tolerances 

• Fully control every aspect of production, from material to performance 

• Cut lead times from months to days 

The result is a fleet of optimized, high-performance UT tools – designed, built, and tested under one roof.
