Cygnus 1 Metal Thickness Gauge

The Cygnus 1 Intrinsically Safe Atex approved 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 echoes and acting as a receiver, converts them into electrical signals which are processed to produce timings in digital form. The multiple-echo beam path is straight, at 90 degrees to the surface and the ultrasonic energy reverberates up and down within the metal. Each time the echo is reflected back down, a small portion of the energy comes up through the coatings, striking the Probe which now acts as a receiver. The delay between echoes at the Probe-face is exactly equal to the time taken to pass through the metal twice, therefore coatings such as paint are ignored and the measurement displayed is of the metal thickness only. To take measurements in air always use a couplant to enable ultrasound to enter the test material. Water, oil or gel are all suitable couplants, depending on application and preference. Ensure that the Probe is correctly fitted with a membrane, and with membrane oil correctly applied. Remove all scale, calciferous marine growth, dirt or loose coating and brush or scrape the test area clean. Protective coatings such as paint or epoxy resin need not be removed, provided that their adherence is good. Place the Probe-face on the clean, lubricated test surface and make firm contact.
