How much do you know about the choice of coating thickness gauge
Coating thickness gauge belongs to an industry collectively. It is also called cladding thickness gauge, coating thickness gauge, paint thickness gauge, galvanized layer thickness gauge, etc. According to different industries and purposes, users The names are different. However, common coating thickness gauges have different detection principles and methods according to different substrates to be measured, so the models will also be differentiated.
Such as: magnetic measurement method and eddy current measurement method, these two methods can be non-destructive testing, without damaging the surface of the object, it can easily measure the coating on the surface
thickness.
In today's society, in order to achieve the protection or decoration of materials, in chemical industry, electronics, electric power, metal, furniture and other industries, spray paint, non-ferrous metals, anodic oxidation film, electroplating layer, etc. are usually used. If it is necessary to detect the surface of the object Overlay thickness, that needs to be applied to the coating thickness gauge.
How to choose a coating thickness gauge?
Here are some tips for you:
First of all, it is necessary to make a judgment according to what kind of metal the substrate of the workpiece to be measured is:
1. Magnetic metal: generally refers to steel and nickel. If it is necessary to measure the thickness of the sprayed coating on the surface of the steel structure, it is only necessary to consider the use of magnetic measurement methods
detection. For example: models that conform to the magnetic measurement principle are: CM8826F, CM8821, CM8822, CM8829SF, CM8825F, etc.
2. Non-magnetic metal: generally refers to aluminum profiles, copper, stainless steel, alloy materials, etc. If you need to detect the coating thickness on the surface of aluminum profiles, you only need to consider
The eddy current measurement method is used for detection. Then the models that conform to the principle of eddy current measurement are: DR310 or DR370, etc.
3. If the workpiece to be measured has both steel structure and aluminum profile, then you can consider using a dual-purpose coating thickness gauge for detection.
Models such as: CM8825N, CM8826N, CM8829SN, CM8823 among the above recommended models, how to choose?
This one mainly depends on the user's usage habits, and the other mainly depends on the structural shape of the workpiece to be inspected by the customer. Furthermore, it is considered from the performance, durability, repeatability, accuracy and price of the instrument. The integrated coating thickness gauge mostly detects flat workpieces. The application range of the integrated coating thickness gauge with wires is wider. Large and small workpieces, flat and curved surfaces can be easily measured.
