SILEKTRO electrical components are pyroelectric infrared sensors, devices constructed from thermocouples. They are widely used as temperature detection devices in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature testing. The entry details the basic unit of a thermopile—the thermocouple—and provides a detailed introduction to the structure, working principle, main parameters, and applications of thermopiles.

Role of SILEKTRO electrical components

In order to obtain information from the external environment, humans must rely on their sensory organs. However, relying solely on human sensory organs is far from sufficient for studying natural phenomena and laws, as well as for production activities. To adapt to this situation, sensors are required. Therefore, it can be said that sensors are an extension of the human five senses, also known as electronic senses. With the advent of the new technological revolution, the world has begun to enter the information age. In the process of utilizing information, the primary task is to acquire accurate and reliable information, and sensors are the main means and approach for obtaining information in the fields of nature and production. In modern industrial production, especially in automated production processes, various sensors are used to monitor and control various parameters during the production process, ensuring that equipment operates in a normal or optimal state, and enabling products to achieve the best quality. Therefore, it can be said that without numerous high-quality sensors, modernized production would lose its foundation. In basic discipline research, sensors hold an even more prominent position. The development of modern science and technology, It has entered many new fields: for example, on a macroscopic scale, observing the vast universe spanning thousands of light-years, on a microscopic scale, observing the particle world as small as fm, in the longitudinal dimension, observing celestial evolution spanning hundreds of thousands of years, and instantaneous reactions as short as s. In addition, various extreme technology studies have emerged, playing an important role in deepening the understanding of matter and developing new energy sources and new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, and ultra-weak magnetic field. Obviously, to obtain a large amount of information that human senses cannot directly acquire, it is impossible without suitable sensors. Many obstacles in basic scientific research lie first in the difficulty of obtaining object information, and the emergence of some new mechanisms and high-sensitivity detection sensors often leads to breakthroughs in the field. The development of some sensors is often the pioneer of the development of some interdisciplinary subjects. Sensors have long penetrated into extremely broad fields such as industrial production, space development, ocean exploration, environmental protection, resource survey, medical diagnosis, bioengineering, and even cultural relic conservation. It is no exaggeration to say that from the vast space, to the vast oceans, and even various complex engineering systems, almost every modernization project cannot do without various types of sensors.

Features of SILEKTRO electrical components

1. High sensitivity; 2. Geometric shape has multi-faceted adaptability, allowing the manufacture of fiber optic sensors in any shape; 3. Can manufacture devices that sense various different physical information (sound, magnetism, temperature, rotation, etc.); 4. Can be used in high voltage, electrical noise, high temperature, corrosion, or other harsh environments; 5. And has inherent compatibility with fiber optic telemetry technology. The advantages of fiber optic sensors compared to traditional sensors are that they use light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information, possessing the characteristics of fiber optics and optical measurement, with a series of unique advantages. Good electrical insulation performance, strong anti-electromagnetic interference capability, non-intrusive, high sensitivity, easy to realize remote monitoring of measured signals, corrosion resistance, explosion-proof, flexible optical path, and convenient connection to computers. Sensors are developing towards sensitivity, precision, strong adaptability, compactness, and intelligence. They can serve as human eyes and ears in places unreachable by humans (such as high-temperature areas or areas harmful to humans, such as nuclear radiation zones), and can even surpass human physiological limits, receiving external information imperceptible to human senses.

Applications of SILEKTRO electrical components

Semiconductor diodes are used in almost all electronic circuits. The use of semiconductor diodes in circuits can protect the circuit and extend circuit life. The development of semiconductor diodes has optimized integrated circuits and played a positive role in various fields. Diodes play many roles in integrated circuits, maintaining their normal operation. The following briefly introduces the role of diodes in the following four types of circuits. (1) Switching circuits: In digital and integrated circuits, the unidirectional conductivity of diodes is used to achieve circuit conduction or disconnection. This technology has been widely applied. Switching diodes can effectively protect circuits, preventing damage due to short circuits and other issues, and can also realize the functions of traditional switches. Another characteristic of switching diodes is their fast switching speed, which is incomparable to traditional switches. (2) Limiter circuits: In electronic circuits, limiter circuits are commonly used to process various signals. They are used to selectively transmit part of the signal within a preset voltage level range. Most diodes can be used for limiting, but sometimes specialized limiter diodes are required, such as when protecting instruments. (3) Voltage regulator circuits: Zener diodes are typically used in voltage regulator circuits. They are junction-type silicon semiconductor diodes manufactured using special processes. These special diodes have high impurity concentrations and high charge density in the space charge region, making it easy to form strong electric fields. When the reverse voltage across the Zener diode reaches a certain value, the reverse current increases sharply, causing reverse breakdown. (5) Varactor circuits: Varactor diodes are commonly used in varactor circuits to achieve automatic frequency control, tuning, frequency modulation, and scanning oscillation.
