Rotating Scanner Probes

Bolt Hole Probes for Evident Rotating Scanners

Rotating scanner probes are used with mechanical devices for automatically rotating the probe in the hole. Probes utilize reflection differential coils with operating frequencies of 200 kHz to 3 MHz. They bear close tolerances and are highly reliable. They are suitable for aluminum structures as well as low conductivity materials.

Rotating scanner probes are available in a variety of diameters and styles to work with Evident rotating scanners. The SPO-5965 and SUB series probes are fitted with a 4-pin Fischer connector while the SPO-3564 series incorporate the 4-pin LEMO connector style.

The probes listed on this page are designed to be rugged and are nearly indestructible. Their probe tips have flexible plastics tips that automatically compress to their original size after being expanded to fit inside larger bolt holes (see chart below for hole size ranges). The benefit of these flexible tips is that no additional manual adjustment has to be made to the probe after a bolt hole has been reamed to a larger diameter.
