How to classify instrumentation?

Instrumentation is a comprehensive product of a variety of science and technology, a wide variety, extensive use, and constantly updated, there are a variety of classification methods. According to the purpose and purpose of use, there are mainly measuring instruments, automotive instruments, tractor instruments, marine instruments, aviation instruments, navigation instruments, driving instruments, radio test instruments, microwave carrier test instruments, geological exploration test instruments, and building materials test instruments. Seismic test instruments, geodetic surveying instruments, hydrological instruments, timing instruments, agricultural test instruments, commercial test instruments, teaching instruments, medical instruments, environmental protection instruments, etc.

Machinery Industry Products Instrument Category

Instruments and meters belonging to the machinery industry include industrial automation instruments, electrical instrumentation, optical instruments, analytical instruments, laboratory instruments and devices, material testing machines, meteorological equipment, film machinery, photo-taking machines, photocopying and micro-mechanics, instruments and meters. There are thirteen categories of devices, instrumentation materials, instrumentation and process equipment. They are more versatile, larger in volume, or necessary for the instrumentation industry.

Classified by different characteristics

Various types of instruments and meters can be further divided into a number of subcategories or subcategories according to different characteristics such as functions, detection control objects, structures, and principles. For example, industrial automation instruments can be divided into testing instruments, loop display instruments, regulating instruments and actuators according to their functions. The measuring instruments are divided into temperature measuring instruments, pressure measuring instruments, flow measuring instruments and level measuring instruments according to the measured physical quantities. Mechanical measuring instruments, etc.; temperature measuring instruments are divided into contact-type temperature measuring instruments and non-contact temperature measuring instruments according to measuring methods; contact-type temperature measuring instruments can be divided into thermoelectric type, expansion type, and resistance type.

Other classification methods

The classification of other types of instruments and meters is generally similar, mainly related to the development process, usage habits and the classification of related products. There is no uniform standard for instrumentation in terms of classification. There are similar situations in the naming of instrumentation.

In practical work, we often classify instrumentation into two major categories: automated instrumentation and portable instrumentation. Automation instrumentation refers to instrumentation that needs to be permanently installed in the field, also known as field instrumentation or dial-mounted instrumentation. The instrument needs to be used in conjunction with other equipment to accomplish one or several functions. Portable instrumentation refers to use alone, and sometimes it is also referred to as test instrumentation. Generally, it is divided into two types: desktop and hand-held.

There is also a classification of instrumentation. It is called a primary instrument and a secondary instrument. A primary instrument is a part of a sensor that directly senses the measured signal, and a secondary instrument is the part that amplifies, displays, and transmits signals.
