summary
Usually a set of devices or machines prepared for a specific purpose. Scientific and educational instruments are generally equipment or devices dedicated to a specific purpose. The construction of scientific and educational instruments is relatively complex and belongs to high-tech products, consisting of multiple components; Teaching instruments are relatively simple and more user-friendly in terms of hands-on operation, maintenance, and updating. There are various types of instruments in terms of volume, weight, and shape. The smallest can be operated directly in the hand, while larger instruments are generally referred to as devices or equipment. General Education Instruments
brief introduction
Scientific and educational instruments can improve, expand, or supplement human senses. People use their sensory organs to see, hear, taste, and touch external objects, and instruments such as microscopes, telescopes, sound level meters, acidimeters, and pyrometers can improve and expand these senses. The physical quantities that can be sensed by measuring instruments such as magnetometers, radiation counters, etc. There are also some instruments and meters that can surpass human abilities to record, calculate, and count, such as high-speed cameras, computers, etc.
classification
Instrumentation is a comprehensive product of various scientific and technological advancements, with a wide variety and widespread use,
And it is constantly updated with multiple classification methods. According to the purpose and use, there are mainly measuring instruments used in scientific research and teaching in various industries, including wireless testing instruments, seismic testing instruments, geodetic surveying instruments, hydrological instruments, timing instruments, agricultural testing instruments, commercial testing instruments, teaching instruments, medical instruments, environmental protection instruments, etc. There are 13 categories of instruments and meters belonging to the mechanical industry products, including industrial automation instruments, electrical instruments and meters, optical instruments, analytical instruments, laboratory instruments and devices, material testing machines, meteorological and marine instruments, film machinery, photographic machinery, micro copying machinery, instrument components, instrument materials, and instrument process equipment. They have strong universality, large batch sizes, or are necessary foundations for the instrumentation industry.
Various types of instruments and meters are further divided into several subcategories or subcategories based on their different characteristics, such as function, detection and control objects, structure, principles, etc. Industrial automation instruments are divided into detection instruments, display instruments, regulating instruments, and actuators according to their functions. Among them, detection instruments are divided into temperature measuring instruments, pressure measuring instruments, flow measuring instruments, level measuring instruments, and mechanical quantity measuring instruments according to the measured physical quantity. Temperature measuring instruments and mechanical quantity measuring instruments, etc. Temperature measuring instruments are divided into contact temperature measuring instruments and non-contact temperature measuring instruments according to the measurement method. Contact temperature measuring instruments are divided into thermoelectric, expansion, and electrochemical types. The classification of other types of instruments and meters is generally similar, mainly related to the development process, usage habits, and classification of related products. There is no unified standard for instruments and meters in the process of refining into steel, and there are similar situations in the naming of instruments and meters.
