Description
To compliment our ultrasonic thickness gauges we offer a range of ultrasonic probes. The performance of any ultrasonic thickness gauge relies heavily on the probe and its suitability to the material being measured. Therefore, selecting the right probe is vital.
Twin crystal probes are used with our gauges in Echo-Echo or Single Echo modes. These types of probes are particularly suited to measuring on heavily corroded metals.
All Cygnus’ probes are made form stainless steel 304 and have a hard wear face which will wear down as the probe is used.
In Echo-Echo mode, up to 1 mm (0.040 inch) of surface coating can be read through and ignored. Single-Echo mode should only be used when there are no surface coatings.
