Roller Probe Transducers are a dry coupled transducer used with a through transmission technique for scanning large areas in an automated system or smaller areas using a hand caliper that can be provided.

Roller probes are typically used in the aerospace industry for the inspection of honeycomb and composite panels and wing sections.

• These probes consist of an anodized aluminium body, Perspex wheel with sealed bearings to prevent leakage of oil and a soft but wear resistant rubber tyre.
• The element is a low or undamped lead zirconate, offering both good penetration and an excellent signal to noise ratio.
• Two sizes of transducer are available, the 25mm diameter which can be held in our own caliper unit or the 75mm diameter to fit individually tailored fixtures.
• Used where dry testing is a necessity in through transmission mode of highly attenuative materials.
• Can be mounted for automated testing or in our own calipers for hand inspection
• Range of frequencies available
• Range of connectors available
• Full refurbishment service available on all roller probes
