Instrument function and function

Instrumentation is used to detect, measure, observe, calculate a variety of physical quantity, material composition, physical parameters of the instrument or equipment. Vacuum leak detector, pressure gauge, length gauge, microscope, multiplier and other instruments are instruments.

Broadly speaking, the instrument can also have automatic control, alarm, signal transmission and data processing functions, such as pneumatic adjustment instrument for automatic control of industrial production process, and electric adjustment instrument, and distributed instrument control system also belong to the instrument.

Instrument function and function

Instruments can improve, extend, or supplement the faculties. People use sensory organs to see, hear, taste and touch external things, and microscope, telescope, sound level meter, acidity meter, high temperature meter, vacuum centrifugal concentrator and other instruments, can improve and expand these senses; In addition, some instruments such as magnetometer, ray counter and so on can feel and measure the physical quantity that human sense organ cannot feel, and some instruments can exceed human ability to record, calculate and count, such as high-speed camera, computer and so on.

Instruments are important tools for the development of science and technology. Mr. Wang Daheng, a famous scientist, pointed out that "machines are tools to transform the world, and instruments are tools to understand the world". Instrument is the "multiplier" of industrial production, the "pioneer" of scientific research, the "combat effectiveness" of military affairs, and the "materialized judge" of modern social activities. It goes without saying that instrument plays a very important role in promoting the development of science and technology and national economy.

Instrument is an important prerequisite and fundamental guarantee for the development of science and technology. Any great leap forward in the history of human development is driven by the great innovation and fundamental reform of tools, and the development and innovation of scientific instruments as "tools" are often the important elements to promote scientific and technological innovation.

Instrument is an important guarantee of economic development and national defense security. Instrument is an indispensable basic condition for economic development and national security. First of all, the famous scientist Qian Xuesen pointed out :" The key technology of the new technological revolution is information technology. Information technology consists of measurement technology, computer technology and communication technology. Measurement technology is the key and foundation.

Instrument is an important force to promote the construction of a harmonious society. Global resource exhaustion, environmental pollution and other problems have become the bottleneck of social healthy development; Food safety problems, public emergencies, disease diagnosis, inflammable and explosive dangerous chemicals and other serious impact on people's lives, the solution of these major problems are inseparable from advanced detection technology and means.

Digitalization and intellectualization

Because of the improvement of micro-electronic skills, instruments and instruments are further integrated with micro-processors, PC skills, and the digital and intelligent degree of instruments and instruments has been improved from time to time. Taking the concept of "DSPS" proposed by Texas Instruments of the United States as an example, the DSP chip is taken as the center to jointly improve the processing scheme of the front including signal signal circuit, ASIC circuit, components and development things to supply the whole system. The instrument adopts many new devices of VLSI, SMT, WSI and MCM, CAD, CAM, CAPP, CAT and other accounting machines. So that multimedia skills, human-computer interaction, absentance, artificial neuron collection and other new skills in modern instruments have been widely used.

Collect the

A variety of intelligent instruments have been facing the market, the instrument is experiencing in-depth intelligent innovation. The integrated test system is also collecting, and each instrument is connected by GPIB bus and VXI bus.

miniaturization

MEMS products include automotive accelerometer, pressure, chemistry, flow transmitter, micro-spectrometer and other products, widely used in science, aerospace, biomedical, automotive industry, military, industrial control and other categories.
