Overview
Sliding probes are specifically designed to inspect rows of fasteners. They operate in reflection mode (driver/pickup coils) and are used to find surface and near-surface flaws.
Sliding probes are available in two different types:
- Adjustable Types: Iinclude shims that allow the probe to be adjusted to accommodate different fastener sizes and include Microdot connectors
- Fixed Types: Capable of finding the same flaws as the adjustable but are usually procedure specific due to coil size and frequency range
The fixed versions typically include the Fischer/LEMO Triax connector and their underside is relieved to enable the probe to easily slide over raised fastener heads.
