The closed top end has a plurality of unitary flexible flaps angularly extending inwardly from an inner surface of the enclosed top end. An inner surface of the tubular body has a plurality of spacers extending radially inward proximate the bottom end of the tubular body. The unitary flexible flaps and the spacers fix the sensor within the tubular body. The tubular body may also have a plurality of capture tabs extending outwardly from an exterior surface thereof proximate the open bottom end that are slidably and removably engageable with an engagement keyway in a retainer bracket that is affixed to a non-metallic and non-magnetic material. | 2018-03-01 |
20180059065 | System and Method for Nondestructive Evaluation of a Test Object - A system for nondestructive evaluation of a test object includes a platform, an electromagnetic acoustic transducer (EMAT) to create acoustic vibrations that travel along the test object; an infrared detector positioned to record thermal images of a plurality of test areas on the test object to detect flaws in the test object as the platform and the test object move relative to each other; and a control connected to actuate the EMAT and the infrared detector, synchronize the creation of vibrations with the recording of thermal images, receive a signal from the infrared detector indicative of the thermal image of the surface of the test object, and record locations of the flaws appearing on the thermal images of the test areas, all as the platform and the test object move relative to each other. | 2018-03-01 |
