Eddy Current Standard Probes
When a coil of conductive wire is excited with an alternating electrical current an alternating magnetic field is produced. The magnetic field oscillates at the same frequency as the excitation source. When placed near a conductive material, currents opposed to the ones in the coil are induced in the material. These are referred to as eddy currents. In the case of variations in the electrical conductivity and/or magnetic permeability causes a change in eddy current. Additionally, the presence of defects will precipitate a change in phase and amplitude that can be detected as a measurable change in the impedance. Eddy Current testing is generally used on conductive materials to detect surface defects.
Ring Probe
Ring probes are made to fit various fastener head diameters and are used for subsurface crack detection with the fastener in place. Ring Probes are also used for finding sub-surface corrosion in structures.
Surface Probe
UniWest manufactures a variety of probes for surface and subsurface inspections. Surface probes are built with a flat bottom to offer better stability on the structure being inspected.
Angled Pencil Probe
Angled Pencil Probes are general purpose probes used for surface inspection in limited access areas.
Standard Pencil Probe
UniWest offers numerous styles of standard pencil probes in addition to manual bolt-hole probes and specialty edge inspection probes.
Sliding Probe
Sliding Probes are used on airframes structures for finding surface or subsurface flaws located near or between fasteners.
Bolt Hole Scanner Probes
Bolt Hole Scanner Probes are most often used in hole or bore inspections. These URB probes can be used with high speed scanners, increasing inspection speed and accuracy in finding flaws.
Surface Following Probe
UniWest manufactures a variety of probes for surface and subsurface inspections. Surface probes are built with a flat bottom to offer better stability on the structure being inspected.
Encircling Probe
Encircling Coils are typically used for on-line inspection of tubes, bars and wires for manufacturing flaws such as inclusions, porosity, cracks, laps, seams, etc.
Cam Follower Probe
The Cam Follower Probes are part of the family of inspection probes engineered and used for the inspection of rotating aircraft engine components. Specific areas of interest are bores and webs.
