Instruments and Apparatuses used to detect, measure, observe, and calculate various physical quantities, material compositions, physical parameters, and the like. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc. are all instruments.

 

Broadly speaking, instrumentation can also have functions such as automatic control, alarm, signal transmission and data processing, such as pneumatic adjustment instruments for automatic control of industrial production processes, and electric adjustment instruments, as well as distributed instrument control systems. Instrumentation.

 

Instrumentation can improve, expand or complement human faculties. People use the sensory organs to see, hear, taste, and touch external things, while instruments such as microscopes, telescopes, sound level meters, acidity meters, pyrometers, vacuum centrifugal concentrators, etc. can improve and expand these functions of humans; in addition, some Instruments such as magnetometers, ray counters, etc. can sense and measure the physical quantities that human sensory organs cannot feel. Some instruments can exceed the human ability to record, calculate and count, such as high-speed cameras, computers, and so on.

 

Instruments are an important "tool" for the development of science and technology. The famous scientist Mr. Wang Dazhao pointed out that "machines are tools for transforming the world, and instruments are tools for knowing the world." The instrument is a "multiplier" for industrial production, a "first mover" for scientific research, a "combat force" for the military, and a "materialized judge" for modern social activities. It goes without saying that instruments play a very important role in promoting the development of science and technology and the national economy in the current era.
