Industrial Manufacturing
Monitoring Production Processes: In industries such as petroleum, chemical, metallurgy, and power generation, pressure gauges are used to monitor the pressure of various gases and liquids in the production process. For example, in an oil refinery, pressure gauges are installed on pipelines and reactors to ensure that the pressure of crude oil, refined oil, and various chemical substances in the production process is within a safe and appropriate range, so as to ensure the normal operation of the production process and product quality4.
Equipment Testing and Calibration: Pressure gauges are used to test and calibrate various pressure equipment and instruments, such as pressure transmitters, pressure switches, and hydraulic cylinders, to ensure their accuracy and reliability. In the automotive manufacturing industry, for example, pressure gauges are used to calibrate the pressure of braking systems, fuel injection systems, and hydraulic suspension systems to ensure the performance and safety of vehicles.
Mechanical Engineering
Hydraulic Systems: In hydraulic systems, pressure gauges are used to measure the pressure of hydraulic oil to monitor the working status of the system. For example, in construction machinery such as excavators, loaders, and cranes, pressure gauges are installed on hydraulic cylinders and hydraulic pumps to help operators understand the pressure changes of the hydraulic system in real time, so as to adjust the operation of the equipment and ensure its normal operation1.
Pneumatic Systems: In pneumatic systems, pressure gauges are used to measure the pressure of compressed air to ensure the normal operation of pneumatic components and systems. For example, in automated production lines, pressure gauges are installed on pneumatic actuators, pneumatic valves, and air compressors to monitor the pressure of compressed air to ensure the accuracy and reliability of pneumatic control1.
Energy Sector
Power Generation: In power plants, pressure gauges are used to monitor the pressure of steam, water, and gas in boilers, turbines, and pipelines. For example, in a thermal power plant, pressure gauges are installed on the steam pipeline and boiler drum to monitor the pressure of high-temperature and high-pressure steam to ensure the safe and efficient operation of the power generation unit.
Oil and Gas Exploration and Production: In the oil and gas industry, pressure gauges are widely used in exploration, drilling, production, and transportation processes. For example, in oil wells, pressure gauges are used to measure the pressure of oil and gas in the wellbore to help engineers understand the reservoir conditions and production potential of the oil and gas field. In addition, pressure gauges are also used to monitor the pressure of pipelines and storage tanks to ensure the safety of oil and gas transportation and storage134.
Aerospace and Defense
Aircraft Systems: In aircraft, pressure gauges are used to monitor the pressure of hydraulic systems, pneumatic systems, and fuel systems. For example, pressure gauges are installed on the hydraulic actuators of aircraft landing gear, flight control surfaces, and brakes to ensure the normal operation of these systems during flight. In addition, pressure gauges are also used to monitor the pressure of the aircraft's fuel tank and fuel supply system to ensure the safety and reliability of fuel supply14.
Military Equipment: In military equipment such as tanks, armored vehicles, and missiles, pressure gauges are used to monitor the pressure of various systems such as hydraulic systems, pneumatic systems, and ammunition storage systems to ensure the normal operation and combat effectiveness of military equipment.
