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
