Magnetic Field Indicator Of Magnetic Particle Testing Pie Gauge is widely used for pressure vessels and general machines, steel forgings and general machines.
Testing equipment and magnetic particle inspection, magnetic suspension comprehensive performance and operation methods.
Put the pointer copper side up, eight low carbon steel faces to the piece and close to it. Using continued method to put the magnetic suspension on the pointer copper, watching magnetic marks show. If detect minute defects, should use the indicator with thick copper, if detect large defects, hould use thin copper indicator.
