Common classification of instrumentationRelease time: 2014-11-19 15:42
Instrumentation is a comprehensive product of a variety of science and technology. It has a wide variety, is widely used, and is constantly updated. There are various classification methods. According to the purpose and purpose of use, there are mainly measuring gauges, automobile meters, tractor meters, marine meters, aviation instruments, navigation instruments, driving instruments, radio test instruments, carrier wave microwave test instruments, geological exploration test instruments, building material test instruments, Earthquake testing instruments, geodetic mapping instruments, hydrological instruments, timing instruments, agricultural testing instruments, commercial testing instruments, teaching instruments, medical instruments, environmental protection instruments, etc.
Instruments and products belonging to the machinery industry include industrial automation instruments, electrical instruments, optical instruments, analytical instruments, laboratory instruments and devices, material testing machines, meteorological instruments, film machinery, photographic machinery, photocopying micro-mechanics, and instrumentation. Thirteen categories are devices, instrumentation materials, and instrumentation process equipment. They are versatile and have large batches, or they are the necessary foundation for the instrumentation industry.
Various types of instruments can be further divided into a number of sub-categories or sub-categories according to different characteristics, such as functions, detection and control objects, structures, and principles. For example, industrial automation instruments can be divided into testing instruments, display instruments, regulating instruments, and actuators according to their functions; among them, measuring instruments are further divided into temperature measuring instruments, pressure measuring instruments, flow measuring instruments, level measuring instruments, and machinery according to the measured physical quantity. Temperature measuring instruments are divided into contact temperature measuring instruments and non-contact temperature measuring instruments according to the measurement methods; contact temperature measuring instruments can be divided into thermoelectric, expansion, resistance and so on.
In order to further improve the various performance of instruments and meters, enhance the ability to withstand various harsh use environments, and improve reliability and service life, instruments and meters will continue to use new working principles and use new materials and new components. For example, the principles of ultrasonic microwave, radiation, infrared, nuclear magnetic resonance, superconductivity, and laser are used, as well as various new types of semiconductor sensitive components, integrated circuits, integrated optical paths, optical fibers, and other components. The purpose is to achieve the miniaturization of instruments, reduce weight, reduce production costs, and facilitate use and maintenance.
