Eddy Current Probes

Olympus eddy current probes consist of the acquired brands of Nortec and NDT Engineering. We offer more than 10,000 standard and custom designed eddy current probes, standard references, and accessories. This section features many of the standard design probes that are available in a wide range of diameters, frequencies, and connector styles.

Olympus also offers custom probe designs to meet specific inspection requirements. Eddy current probes may be designed to match the contours of a part or shaped to fit into a fixture for fast and accurate inspections.

Conductivity Probes and Standards

Conductivity probes are designed for sorting non-ferrous metals, determining heat treatment condition or damage.

Manual Bolt Hole Probes

Manual bolt hole probes have coils located at right angles to the probe direction, and are rotated by hand with the fastener removed. Standard (fractional and metric) and custom diameters are available with absolute and differential coils.

Rotating Scanner Probes

Rotating scanner probes are available in a variety of diameters and styles to work with Olympus 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.

Sliding Probes

Sliding probes are specifically designed to inspect rows of fasteners. They operate in the reflection mode and are used to find surface and near-surface flaws. Adjustable types allow the probe to be adjusted to accommodate different fastener sizes and include microdot connectors. Fixed types are capable of finding the same flaws as the adjustable but usually are procedure specific due to coil size and frequency range.

Spot Probes

Spot probes are used for discovering flaws both on and below surfaces. Available in a broad frequency range, their diameters are usually large for accommodating lower frequencies or scanning large areas. Because spot probes contain larger coil diameters the detectable flaw size also increases and is typically limited to ½ the probe diameter.

Surface Probes

Surface probes have smaller diameter housing and coils built for higher frequencies. Applications are usually limited to surface flaws because of the higher frequency and smaller coil size. Included in this type of probe are the right angle surface probes and flexible surface probes, which are designed to reach areas inaccessible to the standard straight surface probes.

Weld Probes

Weld probes are designed to inspect ferrous welds. They provide a cost effective alternative to magnetic particle inspection, which requires the part to be prepared (cleaned) prior to inspection.
