woox electrical components Germany woox model woox price

woox electrical components are instruments that convert high primary current to low secondary current for measurement based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current needs to be measured. Therefore, it often carries the full current of the line. The secondary winding has more turns and is connected in series in the measuring instrument and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils in series with the measuring instrument and protection circuit is very small, and the operating state of the current transformer approaches a short circuit. The current transformer converts high primary current to low secondary current for measurement; the secondary side must not be open-circuited.

woox electrical components function

To obtain information from the external world, humans must rely on sensory organs. However, relying solely on human sensory organs is far insufficient for studying natural phenomena and laws, as well as for their functions in production activities. To adapt to this situation, sensors are required. Therefore, it can be said that sensors are an extension of the human five senses, also known as electronic five senses. With the advent of the new technological revolution, the world has begun to enter the information age. In the process of utilizing information, the primary issue to address is acquiring accurate and reliable information, and sensors are the main fm and means for obtaining information in the fields of nature and production. In modern industrial production, especially in automated production processes, various sensors are used to monitor and control various parameters in the production process, ensuring that equipment operates in a normal or optimal state and that products achieve the best quality. Therefore, it can be said that without numerous high-quality sensors, modern production would lose its foundation. In basic discipline research, sensors hold an even more prominent position. The development of modern science and technology has entered many new fields: for example, observing the vast universe thousands of light-years away on a macro scale, and observing the particle world as small as fm on a micro scale; observing celestial evolution spanning hundreds of thousands of years vertically, and instantaneous reactions as short as s. In addition, various extreme technology studies have emerged, playing an important role in deepening the understanding of matter, exploring new energy sources, and developing new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic fields, and ultra-weak magnetic fields. Obviously, it is impossible to obtain a large amount of information that human senses cannot directly access without appropriate sensors. Many obstacles in basic scientific research lie first in the difficulty of obtaining object information, and the emergence of some new mechanisms and high-sensitivity detection sensors often leads to breakthroughs in these fields. The development of some sensors is often the pioneer of the development of interdisciplinary subjects. Sensors have long penetrated into extremely broad fields such as industrial production, space exploration, ocean detection, environmental protection, resource survey, medical diagnosis, bioengineering, and even cultural relic preservation. It is no exaggeration to say that from the vast space to the vast ocean, and even various complex engineering systems, almost every modern project relies on various types of sensors.

woox electrical components parameters

The main parameters of potentiometers include nominal resistance, rated power, resolution, sliding noise, resistance change characteristic, wear resistance, zero-position resistance, and temperature coefficient. 1. Rated power: The maximum power allowed to be dissipated on the two fixed terminals of the potentiometer is the rated power of the potentiometer. Note that the rated power is not equal to the power between the center tap and the fixed terminal. The rated power of a potentiometer refers to the maximum power allowed to be consumed under long-term continuous load at the specified rated temperature when the atmospheric pressure is 87~107kPa. 2. Nominal resistance: The nominal resistance marked on the product, whose series is similar to that of resistors. 3. Allowable error class: The error range between the measured resistance and the nominal resistance allows errors of 20%, 10%, 5%, 2%, and 1% depending on the precision class. The precision of precision potentiometers can reach 0.1%. 7. Resistance change law: Refers to the relationship between resistance and the rotation angle (or sliding travel) of the sliding contact. This relationship can be in any functional form, commonly linear, logarithmic, and reverse logarithmic (exponential). In use, linear potentiometers are suitable as voltage dividers; reverse logarithmic (exponential) potentiometers are suitable as volume controllers in radios, recorders, phonographs, and televisions. If a similar product is not found during maintenance, a linear type can be used as a substitute, but a logarithmic type should not be used. Logarithmic potentiometers are only suitable for tone control, etc.

woox electrical components principle

The basic principle of a multimeter is to use a sensitive magnetoelectric DC ammeter (microammeter) as the meter head. When a small current passes through the meter head, there will be a current indication. However, the meter head cannot pass large currents, so some resistors must be connected in parallel and series with the meter head for shunting or voltage reduction, thereby measuring the current, voltage, and resistance in the circuit. The measurement process of a digital multimeter converts the measured quantity into a DC voltage signal via a conversion circuit, then converts the analog voltage into a digital quantity via an analog-to-digital (A/D) converter, then counts via an electronic counter, and finally displays the measurement result directly as numbers on the display screen. The functions of measuring voltage, current, and resistance in a multimeter are realized through the conversion circuit part, and the measurement of current and resistance is based on voltage measurement, meaning that a digital multimeter is expanded on the basis of a digital DC voltmeter. The digital DC voltmeter's A/D converter transforms the continuously changing analog voltage over time into a digital quantity, which is then counted by an electronic counter to obtain the measurement result, and the measurement result is displayed by the decoding display circuit. The logic control circuit controls the coordinated work of the circuit, completing the entire measurement process in sequence under the action of the clock.
