e2Sense – Flexible UT Sensors

The FSA Series from e2Sense enables ultrasonic thickness measurement of pipes from different diameters with a single sensor array.

The flexible sensor array can be used as a stand-­alone probe or mounted on the ElbowScan™ to allow for encoded UT measurements.

The FSA are available in different linear array configurations with operating frequencies of 5, 7.5 and 10 MHz.



  • Pipe thickness measurement – straight sections, intrados or extrados
  • Adapts to pipe diameters – 1 to 12 inches
  • Encoded UT of pipe elbow with ElbowScan™
