EZAutomation electrical components are sensors that convert the state of the measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from the light source into a modulator via an optical fiber. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is guided through the optical fiber, passes through the modulator, and then exits. The optical fiber serves first to transmit the light beam and second to act as an optical modulator.

EZAutomation electrical component structure

For rubber and plastic power cables used for power, lighting, and internal installation in electrical equipment, copper cores are preferred. For large cross-section conductors, compacted stranded cores are recommended. Conductors for fixed installations generally use Class 1 or Class 2 conductor structures. Insulation materials generally include natural styrene-butadiene rubber, polyvinyl chloride (PVC), polyethylene, and nitrile-PVC compounds. Heat-resistant power cables use PVC rated for 90 °C. Sheath materials generally include PVC, cold-resistant PVC, ant-termite PVC, black polyethylene, and neoprene rubber. Black polyethylene and neoprene sheathed power cables are suitable for extreme cold resistance and outdoor overhead installation. In environments with external forces, corrosion, or moisture, rubber or plastic sheathed power cables can be used. Rubber and plastic flexible power cables use copper cores with a flexible structure, composed of multiple single wires twisted together. Flexible conductors generally use Class 5 or Class 6 conductor structures. Insulation materials generally include natural styrene-butadiene rubber, PVC, or soft polyethylene plastic. The cabling lay ratio multiplier is small. The outer protective layer uses cotton yarn braiding to prevent overheating and damage to the insulation layer. To facilitate use and simplify production processes, a three-core balanced structure is adopted, which saves production labor hours and improves efficiency. For shielded insulated power cables, tinning of the conductor cores is permitted in certain applications. The surface coverage density of the shielding layer must comply with standards or meet user requirements. The shielding layer should be braided or wrapped with tinned copper wire. If an extruded sheath is applied over the shield, the shield may use soft round copper wire braiding or wrapping. To prevent internal interference between cores or pairs, individual phase shielding structures for each core (or pair) can be produced. General-purpose rubber-sheathed rubber power cables use soft copper wire bundles with a flexible structure; paper wrapping is permitted on the surface of large cross-sections to improve bending performance. Natural styrene-butadiene rubber is used for insulation, offering good aging resistance. Outdoor products use neoprene rubber or a neoprene-based mixed rubber formula. Mining rubber power cables use copper cores with a flexible structure, composed of multiple single wires twisted together. Flexible conductors generally use Class 5 or Class 15 conductor structures. Rubber is generally used as the insulation material. The cabling lay ratio multiplier is small. Many products use metal braiding to equalize the electric field and improve the sensitivity of insulation status indication. There is a thick outer sheath, and color coding is applied underground in mines to help construction personnel identify different voltage levels of the rubber power cables.

EZAutomation electrical component principle

When two conductors of different compositions (called thermocouple wires or thermoelectrodes) are joined at both ends to form a loop, an electromotive force (EMF) is generated in the loop when the temperatures at the two junctions differ. This phenomenon is called the thermoelectric effect, and the EMF is called thermoelectric potential. Thermocouples use this principle for temperature measurement. The end directly exposed to the medium being measured is called the hot junction (also known as the measuring end), and the other end is called the cold junction (also known as the compensation end). The cold junction is connected to a display instrument or associated instrument, which indicates the thermoelectric potential generated by the thermocouple. A thermocouple is essentially an energy converter that transforms thermal energy into electrical energy, using the generated thermoelectric potential to measure temperature. Regarding the thermoelectric potential of a thermocouple, note the following issues: 1. The thermoelectric potential of a thermocouple is the difference between the temperature functions at the two ends of the hot junction, not a function of the temperature difference between the cold and hot junctions; 2. When the thermocouple material is homogeneous, the magnitude of the thermoelectric potential generated is independent of the length and diameter of the thermocouple, depending only on the composition of the thermocouple material and the temperature difference between the two ends; 3. Once the material composition of the two thermocouple wires is determined, the magnitude of the thermoelectric potential depends only on the temperature difference. If the cold junction temperature is kept constant, the thermoelectric potential is a single-valued function of the hot junction temperature. Two conductors or semiconductors of different materials, A and B, are welded together to form a closed loop, as shown in the figure. When there is a temperature difference between the two junction points 1 and 5 of conductors A and B, an EMF is generated between them, forming a current of a certain magnitude in the loop. Thermocouples operate based on this effect.

EZAutomation electrical component function

The main functions of a potentiometer in a circuit include: 1. Used as a voltage divider. A potentiometer is a continuously adjustable resistor. When the knob or slider is adjusted, the moving contact slides along the resistive element. At this time, the output terminal of the potentiometer provides an output voltage related to the applied voltage and the angle or travel of the movable arm. 2. Used as a rheostat. When used as a rheostat, the potentiometer should be connected as a two-terminal device, allowing a smoothly and continuously changing resistance value within its travel range. 13. Used as a current controller. When a potentiometer is used as a current controller, one of the selected current output terminals must be the terminal connected to the sliding contact.
