Portable Magnetic Generators | MPI Power Units for Field Inspection

Mobile Mpı Power Units

Product Code :
Category :	Magnetic Testing

Product Features
Explanation

Portable magnetic generators are mobile power units designed for Magnetic Particle Inspection (MPI) in field applications. They enable reliable inspection of large, heavy, or fixed components that cannot be moved to a stationary inspection bench.

These units provide flexible, on-site magnetization for MPI testing where conventional bench systems are not practical.

Portable or wheeled configurations
Suitable for large structures and in-situ inspections
Quick setup and easy operation in field conditions

Ideal for on-site magnetic particle inspection of heavy or non-movable components.

Working Principle

Portable MPI generators create a strong magnetic field in the test piece using high current:

Direct current flow (prods or cables)
Coil method (cable wrapping around the part)
Adaptable accessories (coils, flexible cables, mandrels) for various geometries

This allows effective detection of surface and near-surface defects.

Technical Features

Current Output: 1,500 – 10,000 A range
Current Types:
- AC
- HWDC (Half-Wave DC)
Demagnetization: Integrated demag function
Control:
- Analog or digital current display
Adjustable parameters: Current level and shot time
Power Supply: 400–440 VAC / 50–60 Hz
