ELECOVEP electrical components, German ELECOVEP models, ELECOVEP prices

ELECOVEP electrical components are electrical control devices. When the change in the input quantity (excitation) meets specified requirements, they cause a predetermined step change in the controlled quantity within the electrical output circuit. They facilitate interaction 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 function essentially as "automatic switches" that use small currents to control the operation of large currents. Therefore, they perform functions such as automatic regulation, safety protection, and circuit switching in electrical circuits. A relay is an electrical control device that, upon receiving a specified input quantity maintained for a sufficient duration, causes a predetermined step change in the controlled quantity in the electrical output circuit. When the input quantity decreases to a certain level and remains there for a sufficient duration, the device returns to its initial state.

ELECOVEP electrical component parameters

Key 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, typically expressed in lm/W. Luminous efficacy represents the energy-saving characteristics of a light source and is an important indicator for evaluating 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 across different spatial angles, we study 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 at sports venues, if the selected LED single-tube distribution range is very narrow, viewers positioned at larger angles relative to the display will see distorted images. Furthermore, traffic signal lights require recognition by people over a wide area. 3. Regarding the spectral characteristics of LED, we primarily evaluate whether its monochromaticity is excellent, and we must ensure that the main colors—red, yellow, blue, green, and white LED—are pure. In many applications, such as traffic signal lights, color requirements are strict. However, observations indicate that some LED signal lights in China emit green with a blue tint and red as deep red. Based on this phenomenon, specialized research into the spectral characteristics of LED is both necessary and meaningful.

ELECOVEP electrical component classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, level sensors, energy consumption sensors, speed sensors, acceleration sensors, radiation sensors, thermal sensors. 2. By principle: vibration sensors, humidity sensors, magnetic sensors, gas sensors, vacuum degree sensors, biological sensors, etc. 3. By output signal: (1) Analog sensors convert measured non-electrical quantities into analog electrical signals. (2) Digital sensors: convert measured non-electrical quantities into digital output signals (including direct and indirect conversion). (3) Pseudo-digital sensors: convert the measured signal quantity 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 processes for silicon-based semiconductor integrated circuits. Usually, part of the circuitry 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 onto a dielectric substrate (base plate). When using hybrid processes, part of the circuitry can also be fabricated on this substrate. Thick-film sensors are made by coating ceramic substrates, typically made of alumina, with slurries of corresponding materials, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or their variants (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 respects, 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 reasonable to adopt ceramic and thick-film sensors. 5. By measurement objective: Physical sensors are made using characteristics where certain physical properties of the measured substance undergo significant changes. Chemical sensors are made using sensitive elements that can convert chemical quantities, such as the composition and concentration of chemical substances, into electrical quantities. Biological sensors are made using various biological or biomaterial characteristics to detect and identify chemical components in biological bodies. 6. By structure: (1) Basic sensors are the most fundamental single transformation devices. (2) Combined sensors are sensors constructed by combining different single transformation devices. (3) Application-specific sensors are sensors constructed by combining basic or combined sensors with other mechanisms. 13. By mode of action: Sensors can be classified into active and passive types based on their mode of action. Active sensors include acting-type and reaction-type. Such sensors can emit a certain detection signal towards the measured object, detect changes produced in the measured object by the detection signal, or form a signal by generating an effect in the measured object via the detection signal. Those that detect changes in the detection signal are called acting-type, while those that detect responses to form signals are called reaction-type. Radar and radio frequency range detectors are examples of acting-type, while photoacoustic effect analysis devices and laser analyzers are examples of reaction-type. Passive sensors only receive signals generated by the measured object itself, such as infrared radiation thermometers and infrared imaging devices.
