The difference between a film thickness gauge and a thickness gauge
As a non-contact instrument, the film thickness gauge in the entire use of the process do not have to worry about damage to the product, but also do not have to worry about radiation on the human body. The instrument has a very wide range of applications, has become the current market quite popular instrument manufacturers. However, compared with the thickness gauge, what is different about it? Let's take a look at the following introduction.
1, subordinate relationship
Literally, many people will think that the film thickness gauge and thickness gauge is a kind of instrument, in fact, not, simply put, the two should be a subordinate relationship. That is to say, the former belongs to the latter in a classification.
2, different principles
Film thickness gauge is mainly used to measure the thickness of film, sheet and other materials, the measurement of a wide range of not to say, high precision, with the main features of the data output, metric conversion, automatic power-off, any position of the zero and so on. Handheld principle of eddy current and magnetoresistance method, the principle of the desktop includes inductive principle and many other kinds.
3, Division classification
Film thickness gauge belongs to the thickness gauge in accordance with the principle of many classifications, including ultrasonic thickness gauge, laser thickness gauge, pressure thickness gauge, X-ray thickness gauge, white light interference thickness gauge, mechanical contact thickness gauge and electrolytic thickness gauge and so on.
4, application areas
Film thickness gauge is widely used in the metal processing industry, manufacturing industry, chemical industry, commodity inspection and other fields, in these areas its use is very large. It can be used to detect the mass production of parts, can detect the tiny area on the thin coating, can measure the electronic industry or semiconductor industry in the functional coating, can also be used for fully automated measurements, such as measuring printed circuit boards and so on.
Film thickness gauge 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 facilities. The key reason why it has so many uses is because of its outstanding features such as easy operation, small measurement error, high reliability and good stability.
