仪器仪表A（Instrument and meter A） Instrumentation (instrumentation) instrumentation is used to detect, measure, observe and calculate various physical quantities, material components, physical parameters and so on. Vacuum leak detector, pressure gauge, length measuring instrument, microscope, multiplier and so on all belong to instrument and meter. In general, the instrument can also have automatic control, alarm, signal transmission and data processing functions, such as automatic control for industrial production in the process of pneumatic control and electric control instrument, instrument, and distributed instrument control system also belongs to the instrument. Instrument function An instrument can improve, expand, or supplement human faculties. People with sensory organs to visual and hearing, taste, touch and external things, microscope, telescope, sound level meter, pH meter, etc. the pyrometer instrumentation, can improve and expand these faculties; in addition, some instruments such as magnetometer, ray count can feel physical quantity and measurement to the sensory organ cannot feel; some instruments can surpass the ability to record, calculating and counting, such as high-speed camera, computer etc.. Science and technology are the primary productive forces, and instruments are important tools for the development of science and technology. The famous scientist, Mr. Wang Daheng, pointed out that the machine is a tool to transform the world, and the instrument is the tool to know the world.. The instrument is the multiplier of industrial production. It is the chief officer of scientific research. It is the combat effectiveness of military affairs and is a materialized judge of modern social activities. It goes without saying that the instrument plays a very important role in promoting the development of science and technology and the national economy in the current era. 1. instrument is an important prerequisite and fundamental guarantee for the development of
