The replacement of electronic components in electronic measuring instruments

Electronic measuring instruments are widely used in various fields of the national economy and are necessary for the development of national production and technological progress. However, the current status of electronic measuring instruments cannot meet the requirements. Its development path is still very long, the market demand is still large, and its development prospects are very broad. The most commonly used electronic components for manufacturing measuring instruments are: resistors, capacitors, potentiometers, tubes, integrated circuits, etc. The requirements for components are long life and high stability, so 3000 hours of electrolytic capacitors may not meet the requirements. Below, the electrolytic capacitor manufacturer will introduce the development history of electronic measuring instruments.

     Electronic measuring instruments are knowledge- and technology-intensive and are in the midst of rapid development. The basis of electronic measurement is electronic circuit technology, and it also integrates separate measurement equipment or systems composed of signal processing, communication engineering, digital technology, measurement and test technology, computer, microelectronics and software. Through the form of electricity, light quantity, etc., it is possible to measure various parameters in the object to be tested or to control the operation of the system under test. Due to the rapid development of various related technologies, and gradually applied to electronic measurement technology and instruments, coupled with the emergence of more advanced measurement theories and methods, as well as the continuous expansion of the measurement field, electronic measuring instruments and equipment have been in aviation, Aerospace, television, radio, electronics, energy, transportation, communications, information systems, microelectronics and electronic components testing have reached new heights, far beyond the measurement range and accuracy of traditional instruments. Therefore, the quality requirements for electronic components have become even higher, and rapid, real-time, accurate, and automatic measurement has become the mainstream of modern measurement technology and instrument development.

        The development of electronic measuring instruments can be traced back to the 1920s. The development of science and technology has promoted the advancement of electronic technology and promoted the emergence of electronic tubes. Electronic technology has a fast measurement speed, a wide spectrum range, and easy remote control. The electronic technology is quickly applied to measurement technology, leading the measurement instrument into a new historical period. In the 1950s, semiconductor technology began to develop rapidly. Transistors have lower power consumption, smaller size, wider spectrum range, and higher stability than tubes. This makes the tubes quickly replaced by transistors, and the performance is better. Spectrum measuring instrument, oscilloscope, etc. In the 1960s, the emergence of small and medium-sized integrated circuits once again pushed the development of electronic measuring instruments to a higher stage. Integrated circuits integrated a large number of components such as resistors, capacitors, diodes, and triodes into the same small silicon chip. To achieve the trinity of components, materials, and circuits. The application of such integrated circuits in electronic measurement makes the electronic measuring instrument smaller, and at the same time, expands the measurement range and improves the measurement accuracy.

       Capacitors play a very important role in these high-precision measuring instruments. The capacity of the capacitor indicates the amount of energy that can be stored. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal. Among them, high-quality electrolytic capacitors and integrated ICs are the most widely used in measuring instruments, so it is especially important to choose a good electrolytic capacitor factory, and Jinmaoyuan can just meet it.
