ERNI Electronics electrical components are commonly used temperature-sensing elements in temperature measurement instruments. They directly measure temperature and convert the temperature signal into a thermoelectric EMF signal, which is then converted into the temperature of the measured medium by electrical instruments (secondary instruments). The external shapes of various thermocouples often differ significantly depending on requirements, but their basic structures are largely similar, typically consisting of main parts such as hot electrodes, insulating protective tubes, and terminal boxes. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. In industrial production processes, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, thermocouples are widely used. They have many advantages, such as simple structure, ease of manufacturing, wide measurement range, high accuracy, low inertia, and output signals that are easy to transmit over long distances. In addition, since thermocouples are passive sensors that do not require an external power supply during measurement, they are very convenient to use. Therefore, they are often used to measure the temperature of gases or liquids inside furnaces and pipelines, as well as the surface temperature of solids.

ERNI Electronics electrical component applications

AC induction motors are the most widely used among various types of electric motors. They are easy to use, reliable in operation, low in price, and robust in structure, but have a low power factor and difficult speed regulation. Synchronous motors are commonly used for high-capacity, low-speed prime movers. Synchronous motors not only have a high power factor, but their speed is independent of the load size and depends only on the grid frequency. They operate relatively stably. DC motors are often used in applications requiring wide-range speed regulation. However, they have commutators, complex structures, high prices, and difficult maintenance, making them unsuitable for harsh environments. With the development of power electronics technology, AC motor speed control technology has gradually matured, equipment prices have decreased day by day, and they have begun to be applied. The maximum output mechanical power that a motor can handle under a specified duty cycle without causing overheating is called its rated power; attention should be paid to the ratings on the nameplate during use. During motor operation, care must be taken to match the load characteristics with the motor characteristics to avoid runaway or stall. Motors can provide a wide range of power, from milliwatts to tens of thousands of kilowatts. The use and control of motors are very convenient, featuring capabilities such as self-starting, acceleration, braking, reversal, and holding. Generally, when a motor's speed is regulated, its output power changes with the speed.

ERNI Electronics 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 great practical significance, directly affecting the minimum viewing angle of LED display devices. For example, for large color LED screens in sports stadiums, if the selected LED single-tube distribution range is very narrow, viewers at larger angles relative to the screen will see distorted images. Moreover, traffic sign lights also require recognition by people over a wide area. 14. 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 requirements for color are quite strict. However, observations show that some LED signal lights in China emit blue-ish green, and red appears deep red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.
