Energy-saving design refers to the use of scientific and rational approaches in designing domestic pressure transmitters in order to achieve energy conservation and emission reduction. When designing such transmitters, various factors must be taken into account, including the product’s structure, performance, parameters, and manufacturing processes. It is also essential to make use of new technologies, theories, materials, and equipment in order to minimize energy consumption and reduce pollutant emissions during use. When implementing energy-saving designs for domestic pressure transmitters, several basic principles should be followed. Practicality is the first consideration in this process, as these transmitters are meant to be used in practical applications. If practicality is ignored in favor of energy savings alone, the resulting products will serve only as decorations.

Low energy consumption is both the key and ultimate goal of energy-saving design. While ensuring the product’s practicality, it is possible to use low-power circuits and components to reduce energy consumption during use. For example, in analog amplification circuits, low-power operational amplifiers can be used, while digital circuits can employ CMOS components. Combining these with FPGA programmable devices can further enhance the functionality of digital circuits and reduce their energy consumption during operation. When selecting sensors, it is also necessary to consider factors such as performance, parameters, energy consumption, and cost, in order to minimize equipment consumption and achieve energy savings.

Simplicity is another important aspect of designing domestic pressure transmitters. Whenever possible, the functions of these devices should be simplified. Generally, the more functions a device has, the more complex its software and hardware become, which not only makes operation more difficult but also reduces reliability and increases energy consumption during use. Therefore, during design, it is important to simplify the structure of the pressure transmitters, using simple circuit designs and hardware configurations, and relying on software instead of hardware to fulfill the device’s functions and reduce its energy consumption.

Interference sources and noise in circuits are inevitable and difficult to eliminate; therefore, it is crucial to minimize coupling between them. The coupling of disturbances occurs in the following ways. 　　Inductive coupling refers to the phenomenon where there is inductance between two circuits. When the current in one circuit changes, it induces an electromotive force in the other circuit. It represents the equivalent circuit for the electromagnetic coupling between the two circuits. There is mutual inductance between the two circuits, with the mutual inductance coefficient being W. When the disturbance current in circuit 1 changes, an interference voltage is generated in circuit 2 due to electromagnetic coupling, equal to V’. It can be seen that this voltage is proportional to the current I. 　2 Capacitive coupling refers to the presence of parasitic capacitance between two circuits, which generates electrostatic induction and allows changes in charge in one circuit to affect another circuit. In the circuit shown in Figure 2, wire 1 serves as a source of interference, while wire 2 is the transmission line for the domestically produced pressure transmitter. C1 and C2 represent the parasitic capacitances between wires 1 and 2 with respect to ground; C2 also denotes the parasitic capacitance between wires 1 and 2. R2 is the resistance of wire 2 with respect to ground. When there is interference voltage on wire 1, an interference voltage is generated on wire 2 as well. It can be seen that capacitive coupling interference increases as the value of the coupling capacitance increases. 　　3 Leakage current coupling: Leakage current coupling refers to the interference caused by poor insulation, whereby high-voltage circuits leak current to low-voltage circuits through the insulation resistance. The circuit shown is an equivalent circuit diagram based on leakage current coupling; the interference source induces a leakage current into the circuit through the leakage resistance, resulting in an interference voltage of 3.4. Common impedance coupling occurs when two or more circuit layers share a common impedance, and current flows through one of these circuits. A disturbance voltage is generated in another circuit. There are 3 types of common impedance coupling. 　　1) Common impedance coupling of power supply internal resistance. When using one power supply to power multiple electronic circuits or sensors, the high-potential circuits or output currents with large magnitudes flow through the power supply. Due to the internal resistance of the power supply, the voltage drop across this resistance becomes a source of interference. 　　2) Common impedance coupling of common ground wires. In domestic high-quality chips: An analysis of the control role of domestic pressure transmitters in industrial electrical automation, as well as their role in energy conservation and emission reduction. Various signal currents flow through the common ground wire of pressure transmitters; due to the impedance present in this ground wire, interference voltages are generated. 　　3) Common impedance coupling of the signal output circuit. When a domestic pressure transmitter’s signal circuit has multiple loads, any change in one of these loads will affect the other output circuits through common impedance coupling. 　　3.5 Radiation coupling: Radiation coupling refers to the electromagnetic field emitted by E+ of Yu Line Electric Equipment. If a device is placed in such an emission field, it will experience an induced electromotive force that is proportional to the emitted electromagnetic field, thereby causing interference.
