Difference between coating thickness measuring device and ultrasonic thickness measuring device
For coating thickness gauge and ultrasonic thickness gauge difference? In fact, we in the daily use, usually do not deliberately distinguish between them, because the coating thickness gauge and ultrasonic thickness gauge is that there is a difference between the two kinds of thickness gauge, want to understand the coating thickness gauge and ultrasonic thickness gauge relationship, mainly from the concept and the measurement range for the first introduction.
Ultrasonic thickness gauge measuring range has two main categories: a class of ultrasonic thickness gauge measuring range of 0-400mm, different brands and models of ultrasonic measuring instrument measuring range will be different, but we don't want to get entangled in this point, so we provide an approximate range of the above; another type of ultrasonic thickness gauge measuring range of 0-1500μm, the same as this is also an approximate measuring range. From the above two kinds of measurement range we can see, ultrasonic thickness gauge can be divided into two types of measurement products.
Usually talk about the ultrasonic thickness gauge is only the first type of thickness gauge, and the second type of ultrasonic thickness gauge often many people will refer to the coating thickness gauge, because only the thickness of the coating measurement range unit is measured in μm, that is, the coating thickness gauge measurement range of 0-1500 μm. for the coating thickness gauge is not only ultrasonic measurement, and there are such as magnetic thickness gauge coating thickness gauge; eddy current thickness gauge Coating thickness gauge of magnetic thickness measurement method; eddy current thickness measurement method; radiometric thickness measurement method of coating thickness gauge.
According to the above, the coating thickness gauge using ultrasonic thickness measurement method should be a good expression of ultrasonic coating thickness gauge, and for the measurement of the ultrasonic thickness gauge is to mm as the unit of the name can be unchanged. However, some manufacturers produce ultrasonic thickness gauge, can be switched between the above two measurement range mode. So the coating thickness gauge and ultrasonic thickness gauge is that there is a difference between the two kinds of thickness gauge and link.
So, what is the difference between coating thickness gauge and ultrasonic thickness gauge? (Note: the following only to ultrasonic coating thickness gauge and ultrasonic thickness gauge for comparison)
1, ultrasonic thickness gauge measurement range relative to the coating thickness gauge to be larger.
2, coating thickness gauge measurement accuracy is better than ultrasonic thickness gauge.
3, ultrasonic thickness gauge and coating thickness gauge measurement application object will be different.
What is the connection between coating thickness gauge and ultrasonic thickness gauge? (Note: the following only to ultrasonic coating thickness gauge and ultrasonic thickness gauge for comparison)
1, ultrasonic coating thickness gauge and ultrasonic thickness gauge are the use of ultrasonic working principle of the instrument.
2, some ultrasonic thickness gauge measurement mode can be switched to coating thickness gauge measurement.
3, ultrasonic thickness gauge and coating thickness gauge measurement mode is basically the same.
In summary: coating thickness gauge and ultrasonic thickness gauge is indeed two different thickness measurement instruments.
But for both ultrasonic measurement of coating thickness gauge and ultrasonic thickness gauge, they are both the difference and connection. We do not need to distinguish between them in our daily life, if we want to distinguish, but also mainly from the measurement of the range of distinction, for example, the measurement of the thickness of the object within 2mm, we usually need to measure the coating thickness gauge.
