The Pie Gauge is a tool for quickly verifying the direction of magnetic flux on a surface. It is made from eight ferrous segments, braised into a single piece, providing a star pattern of nonferrous discontinuities. The eight linear discontinuities provide indications in all directions. Typically used with dry powders for yoke inspection, the Pie Gauge can be held at any angle and will generate indications perpendicular to the direction of the magnetic flux. Non-ferrous handle with pivot.
Meets ASME BPVC Section V Article 7, ASTM A275, ASTM E709, ASTM E1444 and ASTM E3024 requirements.
