    Cygnus 3 Operating Manual M4-CYG3-M-ENG_Iss2.doc 1. Introduction Cygnus 3 Thickness Gauge The Cygnus 3 Multiple-Echo Ultrasonic Thickness Gauge is a rugged, handheld, battery-powered instrument designed for high- reliability thickness measurement using the multiple-echo technique. The Gauge can be used with a choice of single-crystal Ultrasonic Probes, depending on the thickness and type of material that is to be measured.

  • Page 8: Multiple Echo Measurements

    Triple Echo Verification The Gauge requires 3 equi-spaced return echoes in order to calculate a thickness measurement value (t2=t3). This method ensures the Gauge only displays valid thickness values, the three echoes provide a reliable method of signal verification.

  • Page 9: Cygnus Instruments

    Cygnus 3 Operating Manual M4-CYG3-M-ENG_Iss2.doc Cygnus Instruments Cygnus Instruments Limited, founded in 1983, was the pioneer in the development of the Digital Ultrasonic Multiple-Echo Technique used for measurement through coatings. This has long been the industry standard to ensure that accurate measurements are taken without the need to zero the Gauge or remove any coatings.

    Template that will ultimately populate an Excel spreadsheet with thickness measurements and user field data that has been logged on the Cygnus 3 gauge. This will introduce the concepts behind the template system so you can go on to create your own templates.
  • Page 100 We will need to keep a copy of this spreadsheet handy for when we create the Data Logger Template, we will need to identify the cell locations where we want the thickness measurement values and other information to go, fig. 11.3. shows these cells highlighted.

  • Page 101: Create The Data Logger Template

    1. Click on the View Templates button in the toolbar 2. Click on the New Template button 3. You should see the New Template dialog, fig. 11.4. 4. Type in “WTSURVEY” in the Template File Name box 5. Click on Single Point Record Template 6.

    Cygnus 3 Operating Manual M4-CYG3-M-ENG_Iss2.doc 12. General Points On Thickness Gauging On very rough surfaces and especially if both sides are badly corroded, it is often necessary to move the Probe around to locate a back wall reflector. Sometimes a slight rocking movement can help find reflectors which are otherwise impossible.

  • Page 112: Troubleshooting

    Gauge is having difficulty obtaining more than one echo: • Check the Probe and its membrane are properly assembled. If there are up to 3 fixed bars plus 1 flashing bar, but never any reading - this means the Gauge is receiving unrelated echoes from more than one reflector: •...

    Connecting the Probe on Page 12 3. Is there adequate couplant applied to the material being measured, and is the surface properly prepared? • Check there is plenty of couplant gel applied and there are no air-gaps between the Probe and the material when measuring.

  • Page 114: Care And Servicing

    Do not store the Gauge for long periods in conditions of high humidity. Repairs There are no user serviceable parts inside the Gauge. Therefore all repair work should be carried out by Cygnus Instruments or by an Authorised Cygnus Service centre.
