JDF-1 small light-weight electric eddy current oscillator
Abstract
Principles of operations, methods of use, and technical properties are discussed for a portable eddy current oscillator which need not come in contact with the test sample. The device can be used to measure and test the static frequency of lades, disks, plates, pipes, and other magnetic or nonmagnetic aircraft engine parts. The oscillations of laser holography can also be measured.
