Instrument and meter related knowledge

Instruments and meters related products include: temperature meters, flow meters, pressure meters, mechanical meters (weighing, speed, thickness measurement), liquid level meters, material level meters, display meters, paper/paperless recorders, analytical instruments, calibration Instrumentation, etc. The function of the instrument lies in physical, chemical or biological methods to obtain information about the movement or change of the detected object. In scientific instruments, this kind of instrumentation related products include: temperature meters, flow meters, pressure meters, mechanical meters (weighing, rotating speed, thickness measurement), liquid level meters, material level meters, display meters, paper/no paper Recorder, analysis instrument, calibration instrument, etc.　　The function of the instrument is to obtain information about the movement or change of the detected object by physical, chemical or biological methods. In scientific instruments, this kind of information is often a quantitative representation of the movement of matter, and this means of detecting matter is now often called a sensor. People use the information obtained in this way (information acquisition) to perform selective conversion or analysis calculation (information conversion and processing) through instrument mechanisms or computers, making it a quantitative form that is easy for people to read and recognize expression (display, conversion and use of information) , Or further signal and image, through the display system, to facilitate observation, enter the inventory file or directly enter the automated intelligent operation control system. When it comes to the content of information technology, the important meaning is that instruments and meters are the source of information, mainly sensors. One of the main trends in the development of modern instruments is combination. The information processing, conversion, storage, and display in the instruments are directly connected with information technology. Only sensors are ever-changing, large and small, from the simplest to the most complex, and diverse. For example, the temperature probe can be as small as a needle tip, and the basic particle detection system—accelerator can be as large as kilometers. In today's prosperous era of information technology, the function of the instrument is more embodied in the detection element-sensor.
