Sauter coating thickness of the surface coating thickness measuring instruments, such as a car paint thickness. With an accuracy of 0.1 micron, the Zui has a large range of 2000 microns. Shanghai Island Korea will briefly introduce the specific steps of the Lower Souter Coating Thickness Gauge :

1. Zeroing, that is, zeroing on a specific zero plate, or zeroing on the original substrate to be measured;

2. Adjust the value of the test piece according to the different measurement range of the measured product to reduce the error in measurement.

3 , the coating thickness gauge is still no problem when it is newly purchased, but it is more complicated.

But when the probe is used for a while, the problem comes out. The accuracy of our instruments is greatly reduced during operation. It's hard to grasp. The reason is the principle of the product, which is a fatal flaw, that is, the probe is wound around the coil using a magnet.

4 , a magnetic field is generated after the current is applied, and the magnetic field is irregular.

5 , fortunately, there is now a new type of coating thickness gauge, namely TC1250-0.1F coating thickness gauge, which uses zui new magnetic sensing technology.

6 , that is, the Hall effect we know, Hall discovered in 1879 . By studying the relationship between the Hall voltage and the operating current, measuring the magnetic field and permeability of the electromagnet, and studying the relationship between the Hall voltage and the magnetic field , Hall finds that this potential difference u h is proportional to the current intensity i h and proportional to the magnetic induction b . It is inversely proportional to the thickness d of the sheet .

7, the magnetic field is turned into the rule. This principle is applied to the coating thickness gauge without the need to adjust the test piece. Especially when measuring arc- or concave products, the use is simpler and more convenient.
