fintech electrical components refer to electronic components that generate resonant frequencies, commonly divided into quartz crystal resonators and ceramic resonators. They function to generate frequencies and feature stability and good anti-interference performance, widely used in various electronic products. The frequency accuracy of quartz crystal resonators is higher than that of ceramic resonators, but the cost is also higher. Resonators mainly serve the role of frequency control; all electronic products involving frequency transmission and reception require resonators. Resonator types can be divided into through-hole and surface-mount types based on their form factor.

1, classified by fixing device type: Thermocouples are a primary means of temperature measurement and are widely used, thus there are various requirements for fixing devices and technical performance. Therefore, thermocouple fixing devices are divided into six types: no fixing device, threaded, fixed flange, movable flange, movable flange square angle form, and tapered protection tube. 12, classified by assembly and structural method: Based on the performance and structural method of thermocouples, they can be divided into detachable thermocouples, explosion-proof thermocouples, armored thermocouples, and spring-loaded fixed thermocouples for special applications.

fintech electrical component parameters

Important aspects of the optical parameters of LED include: luminous flux, luminous efficacy, luminous intensity, light intensity distribution, and wavelength. 1. Luminous efficacy is the ratio of luminous flux to electrical power, with the unit generally being lm/W. Luminous efficacy represents the energy-saving characteristics of a light source, which is an important indicator for measuring the performance of modern light sources. 2.LED Luminous intensity characterizes the strength of light emission in a specific direction. Since the light intensity of LED varies significantly at different spatial angles, we have studied the light intensity distribution characteristics of LED. This parameter has significant practical implications, directly affecting the minimum viewing angle of LED display devices. For example, for large-color LED displays in stadiums, if the selected LED single-tube distribution range is very narrow, viewers at larger angles relative to the display will see distorted images. Moreover, traffic sign lights also require recognition by people over a wide area. 8. Regarding the spectral characteristics of LED, we mainly examine whether its monochromaticity is excellent, and pay attention to whether the main colors such as red, yellow, blue, green, and white LED are pure. Because in many occasions, such as traffic signal lights, the color requirements are quite strict. However, observations show that some LED signal lights in China emit blue-ish green and deep red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.

fintech electrical component principle

Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship with the displacement via potentiometer elements. Ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for the purpose of measuring displacement require a definite relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement sensor is connected to the object being measured. The displacement of the object causes a change in resistance at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while the increase or decrease in resistance indicates the direction of the displacement. Typically, a supply voltage is applied to the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps based on the turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltages can cause system oscillation. Therefore, the resistance value per turn should be minimized during the manufacture of the potentiometer. Another major disadvantage of potentiometric sensors is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low price.
