Cygnus gauges have a wide range on single and twin crystal probes available.
Cygnus Ultrasonic Transducers
Description
To complement CYGNUS’ range of ultrasonic thickness gauges they offer a range of ultrasonic probes. The performance of any ultrasonic thickness gauge relies heavily on the quality of the probe and its suitability to the material being measured. Therefore selecting the right probe is vital.
The probe frequency will be determined by the minimum thickness of the material to be measured. However, the lower the probe frequency the more effective the ultrasound will be at penetrating coatings and corrosion. The Single Crystal 2.25 MHz 13mm probe is recommended for the majority of applications as it performs the best on corroded metal and through thick coatings.
| Probe Model | Frequency | Face Size | Single / Twin Crystal | Range In Steel | Typical Applications |
| S5A | 5.0 MHz | 6 mm (1/4”) | Single | 1 to 50 mm | Small diameter pipes and boiler tubes/heat exchangers |
| S5C | 5.0 MHz | 13 mm (1/2″) | Single | 1 to 50 mm | Measuring wall thickness down to 1mm |
| S3C | 3.5 MHz | 13 mm (1/2″) | Single | 2 to 150 mm | Measuring wall thickness down to 2mm with corrosion through coatings |
| S2C | 2.25 MHz | 13 mm (1/2″) | Single | 3 to 250 mm | Standard probe supplied, best for all round measurement of wall thickness with corrosion through coatings. |
| S2D | 2.25 MHz | 19 mm (3/4″) | Single | 3 to 250 mm | Large flat plates with heavy corrosion and/or through thick coatings. |
| T7A | 7.0 MHz | 7.6 mm | Twin | 3 to 25 mm | Small diameter pipes Thin, corroded plate |
| T5A | 5.0 MHz | 10 mm | Twin | 3 tp 50 mm | General purpose Economical probe |
| T5B | 5.0 MHz | 13 mm | Twin | 5 to 50 mm | High power composite probe Surfaces with heavily corroded and pitted front/back walls |
| T2C | 2.0 MHz | 17 mm | Twin | 5 to 50 mm | Attenuative materials |
