PLC Controlled MPI Machine
Our PLC-based MPI test bench units go a step ahead of conventional machines for MPI inspection. They are used across a wide range of industries, such as aerospace, marine automotive, oilfield equipment & railways, for the detection of surface & subsurface defects. These benches are two vector machines. A circular magnetic field is generated by clamping the part between the headstock & tailstock & passing a current through the part. Parts with a central bore can be tested using the threaded bar method. A longitudinal magnetic field is generated changeover is accomplished by solid-state circuitry.
- Adjustable magnetization time of up to 2.0 seconds allows for the complete development of indications
- Available in various amperages, part lengths & coil diameters
- Dark room with a ventilation fan & white light is included in all models for testing with fluorescent powders
- Complies with ASTME3024
Features
- PLC-Based Control. Automatic Cycle for faster testing.
- 7 Inch Touch Screen for control & display.
- Operator controlled an automatic double shot.
- 50 Program memory to store settings for different parts.
- Error displayed on a touch screen for easy diagnostics.
- Independent current control for Circular and longitudinal magnetization.
- Independent transformers for Circular and longitudinal magnetization, thereby avoiding the use of noisy changeover switches.
