Inductive Film Thickness Gauge

The inductive thickness gauge operates based on the principle of electromagnetic induction. The probe generates an alternating magnetic field, which induces eddy currents in the metal substrate. These eddy currents affect the inductance value of the probe, allowing for the measurement of the thickness of non-magnetic coatings or platings. It is used to detect the thickness of paint, plastic, and electroplated layers and finds applications in quality control within the automotive and electronics industries.
