Absolute Eddy Current Probe
The absolute eddy current probe measures the electromagnetic field of a test part with a single measuring coil and outputs absolute values for conductivity or coating thickness. It responds to global field changes.
Physical-Chemical Mechanism of Action
The absolute eddy current probe generates a magnetic field that passes through the test part. The measuring coil measures the change in the magnetic field and outputs an absolute conductivity or coating thickness.
Metallurgical Relevance & Risks in Welding
The probe is especially useful for checking coatings and alloys. Incorrect settings can lead to inaccurate readings, affecting quality assurance.
Shop Practice & Action Guidelines
Use the probe when checking coatings and alloys. Ensure the magnetic field is homogeneous and the measuring coil is correctly aligned. The reference voltage should always be set to 100%.
