  optical fibre sensor

  

  In optical fiber sensor, the transmission characteristics of optical fiber play a key role in measuring accuracy and reliability. The transmission characteristics of optical fiber are influenced by fiber material, fiber structure and light source. Shi Ying glass or plastic is generally used as the material of optical fiber, and its refractive index and attenuation coefficient determine the transmission speed and attenuation degree of optical signals. The structure of optical fiber includes single-mode fiber and multimode fiber, and the light transmission mode inside is different, so different types of optical fiber can be selected for different application requirements. The choice of light source will also affect the transmission characteristics of optical fiber, such as the wavelength and power of light source and other parameters will affect the transmission distance and intensity of optical signals.

  

  In addition to optical fiber transmission characteristics, optical sensing technology is also one of the keys of optical fiber sensors. Optical sensing technology uses the interference, scattering and absorption of optical signals to measure the measured physical quantities. For example, fiber optic gyroscopes use the interference principle of optical signals to measure the rotation angle; Optical fiber temperature sensor uses the thermal scattering effect of optical fiber materials to measure temperature; Optical fiber pressure sensor uses the pressure sensitivity of optical fiber to measure pressure.

  

  Optical fiber sensors are widely used. For example, in the industrial field, optical fiber sensors can be used to measure physical quantities such as pressure, temperature, displacement and vibration, and can be used in machinery manufacturing, petrochemical industry, aircraft, automobiles and other fields. In the medical field, optical fiber sensors can be used in cardiovascular surgery, endoscopic surgery and so on. In the military field, optical fiber sensors can be used in missile guidance, radio interference detection and so on. In the field of scientific research, optical fiber sensors can be used in earthquake monitoring, meteorological detection and other fields.

  

  Another important feature of the application of optical fiber sensor is that it can realize remote measurement. The signal of optical fiber sensor can be transmitted to a remote location through optical fiber for measurement and monitoring. This characteristic can realize the measurement of dangerous environment and inaccessible places, such as deep sea and space. In addition, optical fiber sensors can realize multi-point and distributed measurement, and connect multiple sensors together to realize real-time monitoring of large structures.

  

  Although optical fiber sensors have broad application prospects and high technical advantages, there are still some problems to be solved in practical application. For example, the signal transmission distance of optical fiber sensor is limited, and the signal attenuation and distortion need to be considered; The sensitivity and accuracy of optical fiber sensor need to be further improved to meet higher measurement requirements; The cost of optical fiber sensor is high, so it is necessary to find a technical solution to reduce the cost.

  

  In a word, optical fiber sensor is a kind of high-precision sensor based on optical principle, which has a wide application prospect and technical advantages. In the future development, we can expect the emergence of more advanced optical fiber sensor technology to meet higher measurement requirements and practical application requirements.

What is the function of gears in a mechanical watch How does it work

  Understanding the Function of Gears in a Mechanical Watch: How They WorkIn the long run, automatic mechanical watch The value will be higher and higher, and there will be a great leap in essence. https://www.supertimewatch.com/

  

  Mechanical watches are intricate timepieces that operate through a carefully orchestrated system of gears and springs. These gears, despite their small size, play a crucial role in the precise functioning of a mechanical watch. This article will explore the function of gears in a mechanical watch, how they work, and why they are essential for accurate timekeeping.

  

  The Role of Gears in a Mechanical Watch

  Power Transmission:

  

  From Mainspring to Gear Train: The mainspring, when wound, stores potential energy. This energy needs to be transmitted through a series of gears to the hands of the watch. Gears help transfer this energy smoothly and at controlled rates.

  

  Regulation of Power: Gears regulate the flow of energy, ensuring that the watch operates at a consistent rate. This regulation is crucial for maintaining accurate timekeeping.

  

  Timekeeping Accuracy:

  

  Gear Ratios: Gears have different sizes and teeth counts, which create specific gear ratios. These ratios control the speed at which the watch hands move. For example, the gear ratio between the gears in the gear train determines the rate at which the seconds, minutes, and hours hands advance.

  

  Precision: The precise alignment and meshing of gears ensure that each component of the watch works in harmony, contributing to accurate timekeeping.

  

  How Gears Work in a Mechanical Watch

  

  To understand how gears work in a mechanical watch, let¨s explore the key components and their interactions:

  

  The Gear Train:

  

  Components: The gear train consists of several gears arranged in a specific sequence. The main gears in the train are the center wheel, the third wheel, the fourth wheel, and the escapement wheel.

  

  Function: Each gear in the train has a specific function and interacts with other gears to transmit power and regulate timekeeping. For example, the center wheel rotates at a rate of one revolution per hour, driving the subsequent gears in the train.

  

  The Escapement Mechanism:

  

  Components: The escapement mechanism consists of the escape wheel and the pallet fork. The escape wheel is connected to the gear train, while the pallet fork interacts with the escapement wheel to control its movement.

  

  Function: The escapement mechanism regulates the release of energy from the gear train. It ensures that the gears move at a consistent rate by periodically releasing the energy stored in the mainspring. This controlled release of energy is essential for accurate timekeeping.

  

  The Balance Wheel:

  

  Components: The balance wheel is a small, oscillating wheel that works in conjunction with the hairspring (or balance spring).

  

  Function: The balance wheel oscillates back and forth at a precise frequency. Each oscillation corresponds to a specific time interval. The gear train¨s movement is synchronized with the balance wheel¨s oscillations, ensuring that the watch hands advance at a consistent rate.

  

  Gear Ratios and Synchronization:

  

  Ratios: Gear ratios are determined by the number of teeth on each gear. For instance, a gear with 20 teeth driving a gear with 40 teeth will produce a 2:1 gear ratio, causing the driven gear to rotate at half the speed of the driving gear.

  

  Synchronization: The gears in a mechanical watch are meticulously calibrated to ensure that the hour, minute, and second hands move in perfect synchronization. This synchronization is essential for accurate timekeeping and display.

Do you know what different colors represent on the circuit board

  As the mother of electronic components, circuit board plays an important role in electronic applications. According to different design principles, circuit boards can be divided into single panel, multilayer board, soft board, hard board, soft-hard board and so on.Sufficient data show that pcb circuit board manufacturers It can drive many people to find jobs, thus driving economic development. https://intechcircuit.com/

  

  At present, the common PCB colors on the market are green, black, blue, yellow, purple, red and brown, and white and pink PCBs have appeared recently.

  

  So, why do PCB boards have different colors? Have you found that most of the circuit boards are green, but other colors are rare? Why? Next, Shenzhen Lianxiaobian will give you a wave of knowledge about circuit boards ~

  

  Why do PCBs have different colors?

  

  In the production process of PCB, the final surface of copper layer is smooth and unprotected, whether by additive process or reduction method. Although the chemical properties of copper are not as easy to oxidize as pure copper of aluminum, iron and magnesium in contact with oxygen in water, the thickness of copper layer in PCB circuit board is very thin, and the oxidized copper will become a poor conductor of electricity, which will greatly damage the electrical performance of the whole PCB. In order to prevent copper oxidation, separate the soldered part from the non-soldered part of PCB and protect the surface of PCB, the design engineer will apply a special coating on the surface of PCB to form a protective layer with a certain thickness to block the contact between copper and air. This coating is called solder resist and the material used is solder resist paint. In order to facilitate maintenance and manufacturing, PCB usually needs to print small text on the board. Therefore, engineers added various colors to the solder resist paint, and finally formed a “colorful” circuit board.

  

  Why are green inks widely used?

  

  The color of solder resist mainly depends on the color of solder resist ink. Green ink is the most widely used and the cheapest in the market. In fact, the solder resist ink on the market is not limited to one kind of green, and there are many colors such as red, blue, purple, black and yellow, but green is the most common one. The main reason is that the use of green solder resist ink has the following advantages: it is convenient for optical positioning correction.

  

  The manufacturing process of the circuit board itself includes STM welding process, and this process needs to be tinned and finally verified by AOI. These processes need to be calibrated by optical positioning, and the green background color has a better recognition effect for the instrument. In the yellow room, the visual effect is better. The whole PCB product has to go through the processes of board making and SMT in the production process. Usually, when the circuit board is used in the production and processing of electronic products, there will be some processes that need to pass through the yellow room. According to the optical law, the green circuit board has a better visual effect in the yellow room, and it is easier to check the production of electronic products.

  

  It is beneficial for workers to observe the circuit board.

  

  At present, due to the production process and other problems, the quality inspection process of many lines still depends on the naked eye observation and identification of workers (of course, flying needle testing technology is mostly used at present). It is very tiring to keep staring at the board under strong light. Using green as the background color of circuit board can reduce the damage of strong light to workers’ eyes, so most manufacturers in the market use green PCB at present.

  

  Environmental protection and low cost.

  

  Because the circuit board needs to be recycled at high temperature when it is discarded, and the green solder resist ink will not release toxic gases, recycling is more environmentally friendly. Thanks to the above advantages, the adoption rate of green solder resist ink is the highest and the production process is the most mature. Therefore, the cost of using green solder resist ink to produce circuit boards is also lower.
