The coating thickness gauge uses a magnetic sensor to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel, iron,paint, powder, plastic, rubber, synthetic materials, phosphating layer, chromium, zinc, lead , aluminum, tin, cadmium, porcelain, antimony, oxid

Principle of magnetic attraction force measurementThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating. Using this principle to make a thickness gauge, measurement can be

The high frequency AC signal generates an electromagnetic field in the probe coil, and a vortex is formed therein when the probe is close to the conductor. The closer the probe is to the conductive to substrate, the larger the eddy current and the greater the reflection impedance. This feedback acti

Principle of magnetic suction measurement and thickness gaugeThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating thickness measurement gauge. Using this principle to mak
