    Introduction CYGNUS INSTRUMENTS Cygnus Instruments Limited, founded in 1983, were pioneers in the development of the Ultrasonic Multiple-Echo Technique used for measurement through coatings. This has long been the standard required to ensure that accurate measurements are taken without the need to first zero the Gauge or remove coatings.

  • Page 9: The Multiple-Echo Method

    Introduction THE MULTIPLE-ECHO METHOD The Cygnus 1 ROV Ultrasonic Thickness Gauge works on the pulse-echo principle. The Probe is made to vibrate for a very short period, creating a pulse of ultrasound which enters the test piece. The Probe waits for returned echos and acting as a receiver, converts them into electrical signals which are processed to produce timings in digital form.
