#PAINT DEPTH GAUGE HOW TO#

How to use the paint thickness gauge for different measurement principles of different brands? Generally,the method of use is described in detail in the manual. When the plating layer becomes thick, the current intensity becomes weak, thereby calculating the thickness of the coating layer. When the plating layer is thinned, the eddy current is higher, and the galvanic current passes through the substrate. It refers to a current loop through a probe at a certain depth on the surface of the conductor. (3) The eddy current thickness measurement method

This measurement method is suitable for materials in which sound waves can propagate inside at a constant speed. The thickness of the material is calculated by accurately metering the residence time of the ultrasonic waves in the material. The ultrasonic thickness measurement method generally refers to the use of a probe to emit ultrasonic waves, and the ultrasonic waves are reflected back to the probe when the measured material reaches the material interface. This method is suitable for thickness measurement of non-magnetic coatings or chemical protective layers on magnetic substrates. The magnetic thickness measurement method is a method for determining the thickness of a magnetic coating on a magnetic substrate by using the principle of electric energy. Paint thickness gauges can be divided into five categories based on their measurement principles. So how does a paint thickness gauge work? Here we will look at different types of coating thickness measurementġ. With so many brands of paint thickness gauges on the market, the measurement principle is also diverse.Therefore, the paint thickness gauges for different brands and different production principles are also used differently. Paint film gauges is also called coating thickness gauges.
