1. Industrial automation appearance and control system. This is generally referred to as PA, FA in foreign countries. PA is called process automation, and FA is called factory automation. The appearance and control system used in process automation and factory automation belong to this category, and some parts of the appearance of analytical instruments and electrical instruments also belong to this category. Such as thermocouples, pressure transmitters, etc.
2. Scientific testing instruments. It is an analytical instrument, a testing machine, an optical instrument, a surveying and mapping instrument, etc. The scientific testing instrument is independent, and it is only used to take the sample to the laboratory when doing the test. Therefore, it is very different from the ** class.
3. Appearance of commonly used instruments. This mainly refers to the supply of exterior and other general instruments. The national standard for the appearance of supply was only taken out two years ago, and we have touched a lot of them on weekdays, such as household electricity meters, gas meters, etc. There are also some commonly used ones that we also extract and classify into this category, such as scales, medical instruments, timing instruments and some commonly used optical instruments.
Fourth, the appearance of special instruments. This kind of is actually specially used in a certain field, for example, the appearance of automobiles and motorcycles rises quickly, which gives rise to the appearance of automobiles, motorcycles, etc., and can also be promoted to agriculture, forestry, animal husbandry and fishery
