Patent ID: 7542871

Claim:
A hand held non-destructive testing device comprising: a frame supporting an NDI sensor and incorporating a plurality of wheels mounted to the frame on bogeys for translation across a curved surface to be inspected, springs intermediate the bogies and the frame for resilient vertical translation of the bogies for maintaining the sensor and the wheels in intimate contact with the surface to be inspected; an ergonomic handle mounted to the frame for manually holding and controlling translation of the frame, manually compressing the resilient means to maintain intimate contact of the sensor and having at least one control means for control of the sensor in scanning of the surface under inspection; said NDI sensor having an excitation coil having a plurality of conductor ribbons attached to a flexible membrane mounted to the frame and deformable responsive to the compressing of the resilient means; and a magnetoresitive (MR) array supported within the frame proximate the membrane and surface.
