Toroidal & Split Coil
2 Station Inspection Unit For Circular Components
Consisting of two stations the bespoke built toroidal and split coil bench unit is designed for inspection of circular components without the need for a contact current to energise the test part. This unit can be supplied with a range of accessories including inspection lamps and booths.
Station 1 - Toroidal:
The toroidal station uses a 'pancake' type coil in the bed of the machine and is used for finding circumferential defects. The flux generated from this coil is intensified with a laminated core in the center to give exceptionally strong magnetic fields for inspection - Well within most Aerospace requirements.
Station 2 - Split Coil:
The split coil station 'threads' a component with a three turn split. This allows for radial defects to be found without damaging components - A potential risk when using high currents with other inspection techniques like current flow.
- ‘Pancake’ coil output 1600A x 6 turns (Typically)
- ‘Spilt’ coil output 1200A x 3 turns (Typically)
- Stainless Steel design
- Retractable threading bar and contact arm for ease of loading/unloading
- Power transformers manufactured and tested in-house before installation
- A range of accessories available
