auerswald electrical components Germany auerswald model auerswald price

auerswald electrical components are commonly used temperature-sensing elements in temperature measurement instruments. They directly measure temperature and convert the temperature signal into a thermoelectric EMF signal, which is then converted into the temperature of the measured medium by electrical instruments (secondary instruments). The external shapes of various thermocouples often differ significantly depending on requirements, but their basic structures are largely similar, typically consisting of main components such as hot electrodes, insulating protective tubes, and terminal blocks. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. In industrial production processes, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, thermocouples are widely used due to their many advantages, including simple structure, ease of manufacturing, wide measurement range, high accuracy, low inertia, and output signals suitable for long-distance transmission. Additionally, since thermocouples are passive sensors that do not require an external power supply during measurement, they are very convenient to use and are often employed to measure the temperature of gases or liquids inside furnaces and pipelines, as well as the surface temperature of solids.

auerswald electrical component function

The self-induced EMF in an inductor coil always opposes changes in the current within the coil. Inductor coils impede alternating current; the magnitude of this impedance is called inductive reactance xl, measured in ohms. Its relationship with inductance l and AC frequency f is xl=2πfl. Inductors are mainly classified into high-frequency choke coils and low-frequency choke coils. An inductor coil connected in parallel with a capacitor can form an lc tuned circuit. When the natural oscillation frequency f0 of the circuit equals the frequency f of the non-AC signal, the inductive reactance and capacitive reactance of the loop are equal, causing electromagnetic energy to oscillate back and forth between the inductor and the capacitor; this is the resonance phenomenon of the lc loop. At resonance, the inductive reactance and capacitive reactance of the circuit are equal in magnitude but opposite in direction, resulting in minimum total loop reactance and maximum current (referring to AC signals where f="f9"). The lc resonant circuit has frequency selection capability, allowing it to select AC signals of a specific frequency f.

auerswald electrical component structure

The simplest switch consists of two metal pieces called "contacts." When the two contacts touch, they complete the current circuit; when they do not touch, the current path is open. When selecting contact metals, consideration must be given to their corrosion resistance, as most metals form insulating oxides after oxidation, preventing the contacts from functioning properly. Selection of contact metals also requires considering factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity. Contacts are sometimes plated with corrosion-resistant metals, typically on the contact surfaces, to prevent performance degradation due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are used for the contact surfaces. In addition to contacts, switches contain movable parts that make or break the contact connection. Switches can be classified based on the type of movable part, such as lever switches, push-button switches, and rocker switches, while the movable part can also be other types of mechanical linkages.
