Coating Thickness Gauges are widely used in industrial production thickness measurement, including steel plate thickness, coil belt thickness, etc. Of course, they are also used in laboratory precision measurement, including aerospace, scientific research and development and other fields. So. What kind of failures will occur in the daily application of the coating Thickness Gauge? How to solve it? This article specifically explains the working principle and common faults of the coating Thickness Gauge. What is a Thickness Gauge? A Thickness Gauge is actually an instrument used to detect the thickness of an object. Widely used in industrial production thickness measurement. This type of coating Thickness Gauge can be roughly divided into the following categories according to the different measurement methods: radioactive Thickness Gauges that use α-ray, β-ray, and y-ray penetration characteristics; ultrasonic Thickness Gauges that use ultrasonic frequency changes; and The eddy current Thickness Gauge adopts the eddy current principle; there are also capacitive Thickness Gauges, etc.
