Inductive Thickness Gauge

Inductive thickness gauges operate on the principle of electromagnetic induction. The probe generates an alternating magnetic field, which induces eddy currents in the metal substrate, thereby altering the magnetic field strength. The thickness of the coating is calculated by measuring these changes. It is used to measure the thickness of non-conductive coatings on metal substrates, making it suitable for quality control in industries such as paints and inks.
