How to Use Composite Multi-Gas Detector
What is the difference between coating thickness gauge and ultrasonic thickness gauge? In fact, in our daily use, we usually do not deliberately distinguish between 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 instrument and the ultrasonic thickness gauge is mainly introduced from the concept and measurement range.
There are two main types of measurement ranges of ultrasonic thickness gauges: The first type of ultrasonic thickness gauge has a measurement range of 0-400mm. The measurement ranges of different brands and models of ultrasonic gauges will be different, but we will not worry about this, so we provide the above An approximate range; another type of ultrasonic thickness gauge has a measurement range of 0-1500μm, which is also an approximate measurement range. From the above two measurement ranges, we can know that ultrasonic thickness gauges can be divided into two types of measurement products.
Generally speaking, ultrasonic thickness gauges are only the first type of thickness gauge, and many people often refer to the second type of ultrasonic thickness gauge as a coating thickness gauge, because only the thickness measurement range of the coating is measured in μm. Measuring, that is, the measuring range of the coating thickness gauge is 0-1500μm. As 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 using the eddy current thickness measurement method; and the coating thickness measurement method using the radiation thickness measurement method. instrument.
According to the above description, the best description of the coating thickness gauge using ultrasonic thickness measurement method should be ultrasonic coating thickness gauge, while the name of the ultrasonic thickness gauge whose measurement is in mm can remain unchanged. However, some manufacturers produce ultrasonic thickness gauges that 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 both different and related.
So, what are the differences between coating thickness gauges and ultrasonic thickness gauges? (Note: The following only compares the ultrasonic coating thickness gauge with the ultrasonic thickness gauge)
1. The measurement range of ultrasonic thickness gauge is 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 gauge and coating thickness gauge will be different.
What are the connections between coating thickness gauges and ultrasonic thickness gauges? (Note: 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 ultrasonic waves.
2. The measurement mode of some ultrasonic thickness gauges 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: coating thickness gauges and ultrasonic thickness gauges are indeed two different instruments for measuring thickness, but for coating thickness gauges and ultrasonic thickness gauges that both use ultrasonic measurement, they are existing difference and connection. We do not need to specifically distinguish them in daily life. If we want to distinguish, it is mainly based on the measurement range. For example, to measure objects with a thickness within 2mm, we usually need a coating thickness gauge to measure.
