Single Element Wheel Probes

The Single element wheel probe uses Sonatest NDTS rubber technology for near-dry Ultrasonic coupling. Using a single element 15mm immersion probe, the Single Element Wheel Probe is designed to operate between 1MHz and 10MHz and is available with a low pressure 38mm tyre (shown) and a higher pressure 25mm tyre. It is complete with an optical position encoder and can be connected to any conventional flaw detector such as the Sonatest Masterscan.

Array Wheel Probe - 50mm Array

Our famous patented array wheel probe is the result of many years of research and careful design, in consultancy with our RapidScan 2 customers in the aerospace market. It features a wide conformable rubber tyre which is acoustically matched to water, providing low loss coupling into the test part for high quality results without the need for gel or large quantities of water.

It is ideally suited to hand scanning of large flat or slightly curved parts, covering large areas quickly and efficiently. A central spring loaded roller ensures consistent coupling pressure across the sensor even when scanning narrow parts. Incorporating a 64 element phased array with 0.8mm resolution, and a high resolution position encoder, the Array Wheel Probe provides high quality, high resolution data.

Array Wheel Probe - 10mm Array

For applications where very larger area coverage is required, the 100mm Array Wheel Probe is available. Due to its larger size it is best suited to flat horizontal components, but will scan curved parts too with a simple adjustment of the array angle.
Employing a larger, wider tyre made from the same Sonatest NDTS rubber as our 50mm Wheel Probe, excellent coupling and data quality is achieved. This RapidScan2 sensor uses a 128 element phased array with 0.8mm resolution and position encoder providing twice the area coverage as the 50mm Wheel Probe but with the same resolution.
