Coating thickness gauge and ultrasonic thickness gauge difference
What is the difference between a coating thickness gauge and an ultrasonic thickness gauge? In fact, in our daily use, we usually do not deliberately distinguish them, because coating thickness gauges and ultrasonic thickness gauges are two types of thickness gauges that are both different and related. If you want to understand coating thickness measurement The relationship between the ultrasonic thickness gauge and the ultrasonic thickness gauge is mainly introduced from the concept and measurement range.
There are two main types of ultrasonic thickness gauges: the first type of ultrasonic thickness gauge has a measurement range of 0-400mm, and the measurement range of different brands and models of ultrasonic thickness gauges will be different, but we do not worry about this, so we provide the above An approximate range; the measurement range of another type of ultrasonic thickness gauge is 0-1500μm, which is also an approximate measurement range as above. From the above two measurement ranges, we can see that ultrasonic thickness gauges can be divided into two types of measurement products.
Generally speaking, the ultrasonic thickness gauge is only the first type of thickness gauge, and the second type of ultrasonic thickness gauge is often referred to by many people as the coating thickness gauge, because only the thickness measurement range of the coating is measured in μm. Metrological, that is, the measuring range of the coating thickness gauge is 0-1500μm. For the coating thickness gauge, it is not only the ultrasonic measurement method, but also the coating thickness gauge such as the magnetic thickness measurement method; the coating thickness gauge of the eddy current thickness measurement method; the coating thickness measurement method of the radiation thickness measurement method instrument.
According to the above description, the best expression for the coating thickness gauge using the ultrasonic thickness measurement method should be the ultrasonic coating thickness gauge, and the name of the ultrasonic thickness gauge whose measurement is in mm can remain unchanged. However, the ultrasonic thickness gauge produced by some manufacturers can switch between the above two measurement range modes. Therefore, the coating thickness gauge and the ultrasonic thickness gauge are two types of thickness gauges that are different and related.
So, what are the differences between coating thickness gauges and ultrasonic thickness gauges? (Remarks: The following only compares the ultrasonic coating thickness gauge with the ultrasonic thickness gauge)
1. The measurement range of the ultrasonic thickness gauge is larger than that of the coating thickness gauge.
2. The measurement accuracy of the coating thickness gauge is better than that of the ultrasonic thickness gauge.
3. The measurement application objects of ultrasonic thickness gauge and coating thickness gauge will be different.
What is the connection between the coating thickness gauge and the ultrasonic thickness gauge? (Remarks: The following only compares the ultrasonic coating thickness gauge with the ultrasonic thickness gauge)
1. Ultrasonic coating thickness gauge and ultrasonic thickness gauge are both instruments that use the working principle of ultrasound.
2. Some ultrasonic thickness gauge measurement modes can be switched to coating thickness gauge measurement.
3. The measurement methods of ultrasonic thickness gauge and coating thickness gauge are basically the same.
To sum up: the coating thickness gauge and the ultrasonic thickness gauge are indeed two different instruments for measuring thickness, but for the coating thickness gauge and the ultrasonic thickness gauge, which both use ultrasonic measurement, they are existing difference and connection. We don’t need to distinguish them specifically in our daily life. If we want to distinguish them, it is mainly from the range of measurement. For example, to measure objects with a thickness of less than 2mm, we usually need a coating thickness gauge for measurement.
