330106-05-30-05-02-00 is a displacement measuring device based on eddy current effect. It uses the principle that a metal conductor generates an induced current (i.e. eddy current) in a changing magnetic field to measure the change in distance between the metal conductor and the probe. Eddy current probes are widely used in vibration monitoring, displacement measurement, speed measurement and other fields.

The eddy current probe is usually composed of probe coil, preamplifier, cable and signal processing module. The probe coil is the core component of eddy current sensor, which generates high-frequency magnetic field and detects eddy current generated by the metal conductor under test. The preamplifier is used to amplify the eddy current signal detected by the probe coil and convert it into a standard voltage or current signal. The cable is used to connect the preamplifier to the signal processing module to transmit the measurement signal.

The measurement accuracy and stability of eddy current probes are affected by a variety of factors, 330106-05-30-05-02-00 including the conductivity, permeability, geometry and size of the metal conductor being measured, as well as the geometry, size and current frequency of the probe coil. Therefore, when selecting and using the eddy current probe, it is necessary to comprehensively consider the specific application requirements and the characteristics of the tested object.

In addition, the installation and calibration of the eddy current probe is also a key step to ensure the measurement accuracy. The correct installation position and method ensures that the gap between the probe and the measured object is stable and repeatable, thus improving the accuracy and reliability of the measurement results. At the same time, regular calibration and maintenance is also an important measure to ensure the long-term stable operation of the probe.
