There is a special feature called ‘Deep Coat’ that can allow Cygnus gages to measure metal thickness through up to 3/4″ (20 mm) of coating. Please contact Cygnus for details of how this feature can be enabled on certain gages. Please note however the ability to measure through thick coatings depends entirely on the type of coating, we can not guarantee the gage will measure through every type of coating.
Only Cygnus probes should be used with Cygnus gages. The specifications of Cygnus probes is carefully controlled to ensure optimum performance from your Cygnus gage. Using non-Cygnus probes may cause incorrect or unsatisfactory operation.
Yes. Although the majority of applications require the gages to be used on steel, the gages can be used on a variety of other materials by either entering the known velocity of sound into the gage in metres per second, or by calibrating the gage with a known thickness of the material under test. Typical examples include, aluminium, copper, grey cast iron, magnesium, nickel, mild steel, tool steel, stainless steel, tungsten, monel, inconel, phosphor bronze and brass.
Yes, otherwise an incorrect reading will be shown. For the Velocity Table click here. These are also listed in the manual supplied with the gage.
If only a few measurements are to be taken on a material other than Steel, it may be easier to leave the calibration set for Steel and convert the readings by multiplying by the Conversion Factor for the material being measured:
True Reading = Reading x Conversion Factor
Conversion factors are listed in the Velocity Table. This method avoids unnecessary re-calibration.
All Cygnus gages are calibrated for Steel when they are manufactured and the calibration can be adjusted to suit the type of material under test. Certificates of calibration are issued at the factory. The gages can be returned for recalibration at the customer’s request and in accordance with their own quality requirements. This is usually every 12 months when the equipment can be tested, checked and recalibrated using equipment traceable to national standards.”
The European Standard BS EN 15317 ‘Characterization and verification of ultrasonic thickness measuring equipment’ recommends all gages to be subject to an annual Performance Check to ensure correct operation. All new Cygnus gages are manufactured in accordance with this standard.
Assuming the batteries are good the next thing to check is if the Probe Membrane is fitted correctly, has enough couplant behind it and is not damaged or worn. There are instruction on Probe Membrane care on the Technical Downloads page.
Gain Settings. Some Cygnus gages have a Gain Setting in their menu:
To correctly set the Gain follow these simple steps:
Yes, the Cyglink application will work with all versions of Windows (2000, XP, Vista, 7, both 32 & 64 Bit versions).
However, the serial to USB converter may require the latest driver installing. You can download the latest drivers for the USB to Serial Converters from Technical Downloads
The small grey USB to Serial Port Cable
The Black USB-485 Converter from KK Systems
The company has BS EN ISO 9001:2000 certification for the design, development, manufacture and repair of ultrasonic measuring equipment and associated accessories.
3 years for the instrument and ancillaries.
6 months for the probe.
Cygnus recommends Duracell Procell batteries for all gages that require disposable batteries.
