In a typical Eddy Current Testing setup, the instrument primarily used to measure eddy currents is known as:

In a typical Eddy Current Testing setup, the impedance analyzer is the appropriate instrument for measuring eddy currents. This device works by applying an alternating current through a coil, generating an electromagnetic field. As eddy currents are induced in the conductive test material, changes in the impedance of the coil system can be measured. This allows for the detection of variations in the material under test, such as flaws or changes in conductivity due to material properties.

Implications of the impedance analyzer include its ability to provide detailed information about the phase and magnitude of the eddy currents, which is essential for accurate inspection and evaluation of the test object. Its measurements are pivotal in interpreting the data related to defect detection, material thickness, and other critical parameters in Eddy Current Testing.

While other instruments mentioned have various applications in electronics, they do not specifically cater to the unique requirements of measuring eddy currents in Eddy Current Testing. For instance, an oscilloscope might visualize waveforms but is not designed for impedance analysis, while a signal generator creates signals rather than measuring responses. A multimeter typically measures voltage, current, or resistance but lacks the specific function to analyze frequency and phase relationships necessary for Eddy Current applications.
