Methodology Investigation Automatic Magnetic Recording Borescope.

Abstract

A new improved magnetic recording borescope was designed, constructed and evaluated. This borescope used two Hall-effect sensors to detect the magnetic leakage field associated with cracks in magnetized ferromagnetic material. The borescope can inspect any cannon tube from 90-mm to 8 inches in diameter. Keywords: Inspection methodology, Material testing technology, Magnetic field leakage, Magnetic testing, Borescopes.
