PLC Controlled Magnaflux MPI Machine

Our PLC Controlled Magnaflux MPI Machine 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 &amp 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
