Pie Guage

The Pie Gauge is a simple yet highly effective tool used in Magnetic Particle Inspection (MPI) to determine the direction of magnetic flux on a test surface. It consists of eight ferrous metal segments arranged in a star pattern, separated by non-ferrous material, which creates artificial discontinuities. These discontinuities help inspectors quickly assess the orientation and effectiveness of magnetic field distribution during an MPI test.

This gauge is commonly used with dry powders and is ideal for yoke inspections. It can be positioned at any angle and provides clear indications at right angles (perpendicular) to the applied magnetic flux, helping operators ensure optimal flaw detection.

Key Features:

• Detects Magnetic Flux Direction – Helps verify proper field orientation for effective MPI testing.

• Eight Linear Discontinuities – Provides indications in all directions to assess field strength.

• Non-Ferrous Handle with Pivot – Allows for easy positioning and handling during inspections.

• Durable Construction – Made from high-quality ferrous materials for repeated use.

• Portable & Easy to Use – Suitable for field and laboratory applications.
