A brief discussion on the difference between film thickness gauge and thickness gauge
As a non-contact instrument, the film thickness meter does not have to worry about damage to the product or radiation to the human body during the entire use process. This instrument has a very wide range of applications and has become a popular instrument among manufacturers in the current market. However, what is the difference between it and the thickness gauge? Let's take a look at the following introduction.
1. Subordination
Literally speaking, many people will think that the film thickness gauge and the thickness gauge are the same instrument. In fact, they are not. To put it simply, the two should have a subordinate relationship. In other words, the former belongs to one category of the latter.
2. Different principles
The film thickness meter is mainly used to measure the thickness of coated films, sheets and other materials. It has a wide measurement range and high accuracy. Its main features are data output, metric and inch conversion, automatic power-off, zero setting at any position, etc. . The principles of handheld ones include eddy current and magnetoresistive methods, while the principles of desktop ones include inductance principles and many other methods.
3. Supervisor classification
Thickness gauges to which film thickness gauges belong are divided into many categories according to their principles, including ultrasonic thickness gauges, laser thickness gauges, pressure thickness gauges, X-ray thickness gauges, white light interference thickness gauges, mechanical contact thickness gauges, and Electrolytic thickness gauge, etc.
4. Application fields
Film thickness gauges are widely used in metal processing industry, manufacturing, chemical industry, commodity inspection and other fields, and their uses in these fields are very large. It can be used to detect mass-produced parts, can detect thin coatings on tiny areas, can measure functional coatings in the electronics industry or semiconductor industry, and can also be used for fully automatic measurements, such as measuring printed circuit boards, etc.
The film thickness meter is not only an indispensable testing instrument for controlling and ensuring product quality, but also a commonly used testing instrument for various pipelines and pressure vessels in production equipment. The key reason why it has so many uses is that it is easy to operate and can measure It has outstanding features such as small error, high reliability and good stability.
