The Simple Principle of Coating Thickness Gauge Measuring Coating Thickness
We all know that the purpose of the coating thickness gauge is mainly to measure the thickness of the coating on the surface of the object, which includes measuring the thickness of the coating. So how does the coating thickness gauge realize the test of the coating thickness? ? The professionals of Elcometer coating thickness gauge introduced to us that the coating thickness gauge mainly measures the coating thickness through electromagnetic induction.
The so-called coating thickness is actually the direct distance between the measuring probe of the coating thickness gauge and the ferromagnetic material. There is a probe on the surface of the coating thickness gauge, and the inside of the probe is a closed magnetic circuit. When the direct distance between the magnetic ferrous material product and the probe changes, the closed circuit also changes. This change will Drive the change of inductance and magnetic resistance of the probe coil to measure the coating thickness.
