Non-contact Type Vibration-Voltage Transducer Utilizing Eddy Current : Analysis and Experiments of the Fundamental Characteristics

There are many methods to measure mechanical vibration. Each of them has it's own individuality of the measurement. The auther studied of the new method utilizing eddy current. This transducer can be constructed without contact to the vibrating surface and has a wide frequency range from audio up to some MHz. This paper was described as the analysis and the experiments to get the fundamental characteristics of the apparatus.
