Smartscan electrical components Germany Smartscan model Smartscan price

Smartscan electrical components are components that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance and only impedes changes in current. If the inductor is in a state with no current flowing through it, it will attempt to impede current flow when the circuit is connected; if the inductor is in a state with current flowing through it, it will attempt to maintain the current unchanged when the circuit is disconnected. Inductors are also known as chokes, reactors, and dynamic reactors.

Smartscan electrical component principle

Two conductors of different compositions (called thermocouple wires or hot electrodes) are joined at both ends to form a loop. When the temperatures at the two junctions are different, an electromotive force is generated in the loop. This phenomenon is called the thermoelectric effect, and this electromotive force is called thermoelectric potential. Thermocouples use this principle for temperature measurement. The end directly used to measure the temperature of the medium is called the working end (also known as the measuring end), and the other end is called the cold end (also known as the compensation end). The cold end is connected to a display instrument or matching instrument, which indicates the thermoelectric potential generated by the thermocouple. A thermocouple is actually an energy converter that converts thermal energy into electrical energy and uses the generated thermoelectric potential to measure temperature. Regarding the thermoelectric potential of a thermocouple, attention should be paid to the following issues: 1, the thermoelectric potential of a thermocouple is the difference between the temperature functions at the two ends of the thermocouple's working end, not a function of the temperature difference between the cold end and the working end; 2, the magnitude of the thermoelectric potential generated by a thermocouple, when the thermocouple material is uniform, is independent of the length and diameter of the thermocouple and depends 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 of the thermocouple; if the temperature of the cold end of the thermocouple is kept constant, the thermoelectric potential of the thermocouple is then a single-valued function of the working end temperature. Weld two conductors or semiconductors of different materials, A and B, to form a closed loop, as shown in the figure. When there is a temperature difference between the two junction points 1 and 11 of conductors A and B, an electromotive force is generated between them, thereby forming a current of a certain magnitude in the loop. Thermocouples operate based on this effect.

Smartscan electrical component applications

Dedicated solid-state relays can feature short-circuit protection, overload protection, and overheat protection. When combined with hardwired combinational logic packaging, they can form intelligent modules tailored to user requirements for direct use in control systems. Solid-state relays are widely used in computer peripheral interface equipment, constant temperature systems, temperature regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, and stage lighting control systems; instruments and meters, medical devices, copiers, and automatic washing machines; automatic fire fighting and security systems, as well as switching switches for power capacitors used in grid power factor compensation. Additionally, they are extensively used in explosive-proof, moisture-proof, and corrosion-resistant environments such as chemical plants and coal mines.

Smartscan electrical component function

The self-induced electromotive force in an inductor coil always opposes the change in current in the coil. The inductor coil has an impedance effect on alternating current, and the magnitude of this impedance is called inductive reactance xl, with the unit being ohms. Its relationship with inductance l and AC frequency f is xl=2πfl. Inductors can mainly be divided into high-frequency choke coils and low-frequency choke coils. An inductor coil connected in parallel with a capacitor can form an lc tuning circuit. That is, when the natural oscillation frequency f0 of the circuit is equal to the frequency f of the non-AC signal, the inductive reactance and capacitive reactance of the loop are also equal, so electromagnetic energy oscillates back and forth between the inductor and capacitor. This is the resonance phenomenon of the lc loop. At resonance, the inductive reactance and capacitive reactance of the circuit are equal in value but opposite in direction, the total inductive reactance of the loop is minimal, and the current is maximal (referring to AC signals where f="f5"). The lc resonant circuit has the function of selecting frequencies and can select AC signals of a certain frequency f.
