6ES71366BA000CA0 electrical components utilize the excellent conductivity and fluidity of mercury to control the opening and closing of electrical circuits. They consist of a glass tube, mercury, fixed electrodes, lead wires, and other parts. After evacuating the air from the tube, it is filled with various gases and sealed. These components are suitable for environments containing dust, oil, water vapor, and corrosive gases, and can also serve as explosion-proof switches in areas with explosive gases. Due to the high surface tension and specific gravity of the mercury inside the tube, along with its fluidity, even a slight tilt of the glass tube causes the mercury's position to change immediately, making surface contact with the electrodes. Thus, they can be used to switch large AC and DC currents. Additionally, these switches feature a lifespan of several million cycles at rated current, compact size, high sensitivity, no mechanical noise, and low cost, making them widely used as automatic control switches.

A thermopile is a pyroelectric infrared sensor composed of thermocouples. It is widely used as a temperature detection device in applications such as ear thermometers, radiation thermometers, electric ovens, and food temperature monitoring. A thermopile consists of two or more thermocouples connected in series, where the thermoelectric potentials output by each thermocouple are superimposed. It is used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made in wire-type or thin-film types, as well as multi-channel and array devices.

A solid-state relay consists of three parts: the input circuit, isolation, and output circuit. Based on different input voltage categories, input circuits can be classified into DC input circuits, AC input circuits, and AC/DC input circuits. Some input control circuits are compatible with TTL/CMOS, featuring positive/negative logic control and inversion functions, allowing easy connection to TTL and MOS logic circuits. For control signals with fixed control voltage, resistive input circuits are used. The isolation and coupling methods between the input and output circuits of solid-state relays include optocoupling and transformer coupling. Optocoupling typically uses photodiode-phototransistor pairs, photodiode-triac optocouplers, or photovoltaic cells to achieve isolation control between the control side and the load side. High-frequency transformer coupling utilizes self-excited high-frequency signals generated by the input control signal, which are coupled to the secondary side, demodulated, rectified, and processed by logic circuits to form drive signals. The power switch of the solid-state relay is directly connected to the power supply and load terminals to switch the load power on and off. Commonly used components include high-power bipolar transistors, SCRs, triacs, power MOSFETs, and IGBTs. The output circuit of a solid-state relay can also be categorized into DC output, AC output, and AC/DC output types. Based on load type, they are divided into DC solid-state relays and AC solid-state relays. For DC output, bipolar devices or power MOSFETs can be used; for AC output, two SCRs or one triac are typically used. AC solid-state relays are further classified into single-phase and three-phase AC solid-state relays. Based on the timing of conduction and turn-off, AC solid-state relays are divided into random-turn-on and zero-crossing types.

6ES71366BA000CA0 Electrical Component Principle

When two different conductors or semiconductors, A and B, form a loop with their ends connected, an electromotive force (EMF) is generated in the loop if the temperatures at the two junctions differ. One junction, at temperature T, is called the working end or hot end; the other, at temperature T0, is called the free end or cold end. The direction and magnitude of this EMF depend on the materials of the conductors and the temperatures of the two junctions. This phenomenon is known as the "thermoelectric effect." The loop formed by the two conductors is called a "thermocouple," the conductors are called "thermoelectrodes," and the generated EMF is called "thermoelectric EMF." Thermoelectric EMF consists of two components: the contact EMF between the two conductors and the temperature difference EMF within a single conductor. The magnitude of the thermoelectric EMF in a thermocouple loop depends only on the conductor materials and the temperatures of the two junctions, not on the shape or dimensions of the thermocouple. Once the electrode materials are fixed, the thermoelectric EMF is a function of the difference between the junction temperatures t and t0. This relationship is widely applied in practical temperature measurement. Since the cold end temperature t0 is constant, the thermoelectric EMF generated by the thermocouple changes only with the temperature of the hot end (measurement end). Thus, a specific thermoelectric EMF corresponds to a specific temperature. Temperature measurement is achieved by measuring the thermoelectric EMF. The basic principle of thermocouple temperature measurement is that a closed loop formed by two dissimilar homogeneous conductors generates a current when a temperature gradient exists between the ends, resulting in an EMF (thermoelectric EMF), known as the Seebeck effect. The two dissimilar homogeneous conductors serve as thermoelectrodes; the higher-temperature end is the working end, and the lower-temperature end is the free end, which is usually maintained at a constant temperature. Thermocouple calibration tables are created based on the functional relationship between thermoelectric EMF and temperature. These tables are derived under the condition that the free end temperature is 3 °C; different thermocouples have different calibration tables. When a third metal material is introduced into the thermocouple loop, the thermoelectric EMF remains unchanged as long as the temperatures at the two junctions of this material are identical. Therefore, the influence of the third metal is negligible. In thermocouple temperature measurement, measuring instruments can be connected to measure the thermoelectric EMF, thereby determining the temperature of the measured medium. For accurate measurement, the cold end temperature (the end connected to the measurement circuit via lead wires, while the measurement end is the hot end) must remain constant so that the thermoelectric EMF is proportional to the measured temperature. Changes in the cold end (ambient) temperature during measurement significantly affect accuracy. Compensating for the effects of cold end temperature variations is known as thermocouple cold junction compensation. Dedicated compensation wires are used to connect to the measuring instrument. Calculation methods for thermocouple cold junction compensation: (1) From millivolts to temperature: Measure the cold end temperature, convert it to the corresponding millivolt value, add it to the thermocouple's millivolt reading, and convert the sum to temperature. (2) From temperature to millivolts: Measure the actual temperature and the cold end temperature, convert both to millivolt values separately, subtract them to obtain the net millivolt value, and then determine the temperature.
