The difference between coating and ultrasonic thickness gauges
What is the difference between coating thickness gauges and ultrasonic thickness gauges? In fact, in our daily use, we usually do not deliberately distinguish between coating thickness gauges and ultrasonic thickness gauges because they have both differences and connections. To understand the relationship between coating thickness gauges and ultrasonic thickness gauges, we mainly introduce the concept and measurement scope in advance.
There are two main types of measurement ranges for ultrasonic thickness gauges: one type has a measurement range of 0-400mm, and the measurement range may vary for different brands and models of ultrasonic thickness gauges. However, we will not dwell on this point, so we provide a rough range above; Another type of ultrasonic thickness gauge has a measurement range of 0-1500 μ m, which is also an approximate measurement range. From the above two measurement ranges, we can see that ultrasonic thickness gauges can be divided into two types of measurement products.
The commonly used ultrasonic thickness gauge is only the first type of thickness gauge, while the second type of ultrasonic thickness gauge is often referred to as a coating thickness gauge by many people, because only the thickness measurement range of the coating is measured in μ m, that is, the measurement range of the coating thickness gauge is 0-1500 μ m. For coating thickness gauges, there are not only ultrasonic measurement methods, but also coating thickness gauges such as magnetic thickness measurement methods; Coating thickness gauge using eddy current thickness measurement method; A coating thickness gauge using the radiometric method.
According to the above description, the best description for a coating thickness gauge using ultrasonic thickness measurement method should be an ultrasonic coating thickness gauge, while the name of an ultrasonic thickness gauge measuring in millimeters can remain unchanged. However, some manufacturers produce ultrasonic thickness gauges that can switch between the two measurement range modes mentioned above. So, coating thickness gauge and ultrasonic thickness gauge are two types of thickness gauges that have both differences and connections.
So, what are the differences between coating thickness gauges and ultrasonic thickness gauges? (Note: The following is only a comparison between ultrasonic coating thickness gauges and ultrasonic thickness gauges.)
1. The measurement range of ultrasonic thickness gauge is relatively larger than that of coating thickness gauge.
2. The measurement accuracy of coating thickness gauge is better than that of ultrasonic thickness gauge.
3. The measurement application objects of ultrasonic thickness gauges and coating thickness gauges may vary.
What is the connection between coating thickness gauge and ultrasonic thickness gauge? (Note: The following is only a comparison between ultrasonic coating thickness gauges and ultrasonic thickness gauges.)
1. Ultrasonic coating thickness gauge and ultrasonic thickness gauge are both instruments that utilize the working principle of ultrasonic waves.
2. Some ultrasonic thickness gauges can switch to coating thickness gauge measurement mode.
3. The measurement method of ultrasonic thickness gauge and coating thickness gauge is basically the same.
In summary, coating thickness gauges and ultrasonic thickness gauges are indeed two different instruments for measuring thickness. However, for coating thickness gauges that both use ultrasonic measurement, they have both differences and connections. We don't need to distinguish them specifically in our daily lives. If we want to distinguish them, it mainly depends on the measurement range. For example, when measuring objects with a thickness of less than 2mm, we usually need a coating thickness gauge for measurement.
