Magnaflux Pie Field indicator

The Magnaflux Magnetic Pie Field Indicator, also known as a pie gauge, is a device used as an aid in determining the direction of magnetic field for detection of discontinuities in ferrous materials. The Pie Gauge is a great tool for quickly verifying the direction of magnetic flux on a surface.

Magnetic Field Direction Indicator - Made from eight ferrous segments, braised into a single piece, providing a star pattern of nonferrous discontinuities

Key Features

• Eight-Segment Design: Made from eight ferrous segments braised into a single piece for comprehensive flux direction detection
• Star Pattern Generation: Creates a star pattern of nonferrous discontinuities to clearly show magnetic field direction
• Versatile Positioning: Can be held at any angle and will generate indications perpendicular to the direction of magnetic flux
• Dry Powder Compatible: Typically used with dry powders for yoke inspection applications
• Quick Verification: Provides rapid assessment of magnetic flux direction on surfaces

Applications

• Determining magnetic field direction in ferrous materials
• Detection of discontinuities during magnetic particle testing
• Yoke inspection with dry powder applications
• Quality control verification of magnetic flux patterns
• Training and demonstration of magnetic field principles

Specifications

This pie gauge generates indications perpendicular to the direction of the magnetic flux, making it an essential tool for NDT professionals who need to quickly verify magnetic field direction during ferrous material inspection processes.
