Fingertip probes for precision thickness gauging

Fingertip probes for precision thickness gauging

05 May 2020

Fingertip probes are perfect suited for thickness measurements on small surfaces and spots that are hard to reach. In addition, these small surface probes make measurements on curved surfaces much easier.

SONOTEC GmbH has unique know-how for the production of piezocomposites. The PXS and TXS fingertip probe series are manufactured with SONOTEC Piezocomposite Technology at SONOTEC headquarters in Germany. The small surface probes are used in a wide range of UT (ultrasonic testing) applications, just to name a few:

  • TXS7.5: Dual element probe for corrosion testing and detection of small pitting
  • PXS10: Single element probe with exchangeable delay line for thin materials
  • PXS15: Single element probe with exchangeable delay line for spot weld testing

The specialist for ultrasonic solutions guarantees highest quality and an outstanding reproducibility of the acoustic properties of every single probe.


Founded in 1991, SONOTEC GmbH has developed into one of the world's leading product and solution specialist for innovative measurement technologies. With more than 170 employees and a modern corporate structure comprising three independent business units - Preventive Maintenance, Nondestructive Testing and Non-invasive Fluid Monitoring - the technology leader operates its global sales activities from the Halle (Saale) based German headquarter. The distributed portfolio includes customized ultrasonic transducers and sensors as well as testing devices and measurement solutions for a variety of different industries.
