ELECOVEP electrical components Germany ELECOVEP model ELECOVEP price

ELECOVEP electrical components are electrical control devices. When the change in the input quantity (excitation quantity) meets specified requirements, they cause a predetermined step change in the controlled quantity in the electrical output circuit. They have an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Typically applied in automated control circuits, they effectively function as "automatic switches" that use small currents to control large current operations. Therefore, they play roles in automatic regulation, safety protection, and circuit switching in electrical circuits. A relay is an electrical control device that can accept a specified input quantity and maintain it for a sufficient duration to cause a predetermined step change in the controlled quantity in the electrical output circuit. When the input quantity drops to a certain level and remains there for a sufficient duration, it returns to its initial state.

ELECOVEP 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 and 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, in large-color LED displays in sports 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 range. 3. 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-green for green and deep red for red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.

ELECOVEP electrical component classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, liquid level sensors, energy consumption sensors, speed sensors, acceleration sensors, radiation sensors, thermal sensors. 2. By principle: vibration sensors, humidity-sensitive sensors, magnetic-sensitive sensors, gas-sensitive sensors, vacuum degree sensors, biological sensors, etc. 3. By output signal: ① Analog sensors can convert non-electrical quantities being measured into analog electrical signals. ② Digital sensors: convert non-electrical quantities being measured into digital output signals (including direct and indirect conversion). ③ Pseudo-digital sensors: convert the signal quantity being measured into frequency signals or short-period signal outputs (including direct or indirect conversion). ④ Switch sensors: when a measured signal reaches a specific threshold, the sensor correspondingly outputs a set low-level or high-level signal. 4. By manufacturing process: Integrated sensors are manufactured using standard production technologies for silicon-based semiconductor integrated circuits. Usually, part of the circuit used for preliminary processing of the measured signal is also integrated on the same chip. Thin-film sensors are formed by depositing thin films of corresponding sensitive materials on a dielectric substrate (base plate). When using hybrid processes, part of the circuit can also be fabricated on this substrate. Thick-film sensors are made by coating slurries of corresponding materials onto ceramic substrates, typically made of alumina, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or certain variant processes (sol-gel, etc.). After appropriate preparatory operations, the formed elements are sintered at high temperatures. There are many common characteristics between thick-film and ceramic sensor processes; in some aspects, thick-film technology can be considered a variant of ceramic technology. Each process technology has its own advantages and disadvantages. Due to lower capital investment required for research, development, and production, as well as the high stability of sensor parameters, it is more reasonable to adopt ceramic and thick-film sensors. 5. By measurement purpose: Physical sensors are made using properties where certain physical characteristics of the measured substance undergo significant changes. Chemical sensors are made using sensitive elements that can convert chemical quantities such as composition and concentration of chemical substances into electrical quantities. Biological sensors are made using various biological or biomaterial properties to detect and identify chemical components in living organisms. 6. By structure: ① Basic sensors are the most fundamental single transformation devices. ② Combined sensors are composed of different single transformation devices. ③ Application-specific sensors are composed of basic or combined sensors integrated with other mechanisms. 13. By mode of operation: Sensors can be classified into active and passive types based on their mode of operation. Active sensors include action-type and reaction-type. Such sensors can emit a certain detection signal towards the object being measured, detect changes produced in the object by the detection signal, or form a signal through effects generated in the object by the detection signal. Those detecting changes in the detection signal are called action-type, while those detecting responses forming signals are called reaction-type. Radar and radio frequency detectors are examples of action-type, while photoacoustic effect analysis devices and laser analyzers are examples of reaction-type. Passive sensors only receive signals generated by the object itself, such as infrared radiation thermometers and infrared imaging devices.
