36/6/2 electrical components utilize the good 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, etc. After evacuating the air from the tube, it is filled with various gases and sealed. It is suitable for environments with dust, oil, water vapor, and corrosive gases, and can also be used as an explosion-proof switch in places with explosive gases. Given the high surface tension and specific gravity of the mercury inside the tube, along with its fluidity, the position of the mercury changes immediately with even a slight tilt of the glass tube, and makes contact with the electrodes via surface contact, thus enabling the switching of high AC and DC currents. Additionally, this type of switch features a service life of several million cycles at rated current, compact size, high sensitivity, no mechanical noise, and low cost, making it commonly used as a switch for automatic control.

36/6/2 electrical component principle

The Hall voltage changes with the magnetic field strength; the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall voltage value is very small, typically only a few millivolts, but after amplification by an amplifier in an integrated circuit, the voltage can be amplified enough to output a stronger signal. To enable the Hall integrated circuit to function as a sensor, mechanical methods are required to change the magnetic field strength. A rotating impeller is used as a switch to control magnetic flux. When the impeller blades are in the air gap between the magnet and the Hall integrated circuit, the magnetic field deviates from the integrated chip, and the Hall voltage disappears. In this way, changes in the output voltage of the Hall integrated circuit can indicate a specific position of the impeller drive shaft. Using this working principle, the Hall integrated circuit chip can be used as an ignition timing sensor. Hall effect sensors belong to passive sensors; they require an external power supply to operate, a characteristic that allows them to detect low-speed operation.

36/6/2 electrical component types

Commonly used thermocouples can be divided into two major categories: standard thermocouples and non-standard thermocouples. Standard thermocouples refer to those for which national standards specify the relationship between thermoelectric potential and temperature, permissible errors, and have a unified standard reference table; matching display instruments are available for selection. Non-standardized thermocouples are inferior to standardized thermocouples in terms of usage range or magnitude, generally lack a unified reference table, and are mainly used for measurements in certain special occasions. Theoretically, any two different conductors (or semiconductors) can be configured into a thermocouple, but as practical temperature-measuring elements, they are subject to multiple requirements. To ensure reliability in engineering technology and sufficient measurement accuracy, not all materials can form thermocouples. The basic requirements for thermocouple electrode materials are generally: 1, stable thermoelectric properties within the temperature measurement range, not changing over time, sufficient physical and chemical stability, and resistance to oxidation or corrosion; 2, small resistance temperature coefficient, high conductivity, and low specific heat; 3, large thermoelectric potential generated during temperature measurement, with a linear or near-linear single-valued functional relationship between thermoelectric potential and temperature; 8, good material reproducibility, high mechanical strength, simple manufacturing process, and low price.

36/6/2 electrical component principle

P-type semiconductors are formed by doping intrinsic semiconductors (a completely pure, structurally complete semiconductor crystal) with a small amount of trivalent element impurities, such as boron. Since boron atoms have only three valence electrons, they form covalent bonds with surrounding silicon atoms. Due to the lack of one electron, a vacancy is created in the crystal. When electrons on adjacent covalent bonds gain energy, they may fill this vacancy, causing the boron atom to become an immobile negative ion, while the covalent bond of the original silicon atom forms a hole due to the missing electron, but the entire semiconductor remains neutral. In this P-type semiconductor, conduction is primarily via holes, with holes as the majority carriers and free electrons as the minority carriers. The principle of N-type semiconductor formation is similar to that of P-type. Pentavalent atoms, such as phosphorus, are doped into the intrinsic semiconductor. After doping, they form covalent bonds with silicon atoms, generating free electrons. In N-type semiconductors, electrons are the majority carriers, and holes are the minority carriers. Therefore, doping trivalent and pentavalent impurity elements into two different regions of an intrinsic semiconductor forms P-type and N-type regions. Based on the characteristics of N-type and P-type semiconductors, it is known that a concentration difference of electrons and holes appears at their junction. Both electrons and holes diffuse from areas of high concentration to areas of low concentration, and their diffusion disrupts the electrical neutrality at the original junction. PN junction unidirectional conductivity: when a forward voltage V is applied across the PN junction, the equilibrium state of the PN junction is broken under the influence of this external electric field. Holes in the P region and electrons in the N region both move towards the PN junction. Holes neutralize the negative ions in the P region of the PN junction, and electrons neutralize the positive ions in the N region of the PN junction, thereby narrowing the PN junction. As the external electric field increases, diffusion motion is further enhanced, and drift motion is weakened. When the external voltage exceeds the threshold voltage, the PN junction acts as a resistor with very low resistance, meaning the PN junction is conducting.
