Rotating Bolt Hole Scanner  Probes

Adjustable Universal Rotating Bolt Hole Scanner Probes (URBA) are most often used in hole or bore inspections.

These URBA bolthole probes can be used with high speed scanners, increasing inspection speed and accuracy in finding flaws. Typically scanner bolt-hole probes are utilized in aerospace structural inspection after removal of fasteners, bushings, or other open hole type inspection applications. Standard URBA probes are designed with a differential reflection coil configuration. The standard probe working length is 2.25" >= 0.312" probe diameter, 1.35" if probe diameter is <0.312".
