A stainless steel pressure gauge is a device used to measure the force exerted perpendicularly on a unit area, commonly referred to as pressure. In the International System of Units (SI), pressure is measured in Pascals, where 1 Pascal equals 1 Newton per square meter. In China, Pascal is the official unit of pressure measurement.

When it comes to seismic pressure gauges, several key pressure types are typically involved: 1. Absolute pressure refers to the total pressure acting on a surface, represented by the symbol "pi." An instrument that measures absolute pressure is known as an absolute pressure gauge. 2. Atmospheric pressure is the pressure caused by the weight of the air column above the Earth's surface. It varies with location, altitude, and weather conditions, and is measured using a barometer, denoted by "pd." 3. Gauge pressure is the difference between absolute pressure and atmospheric pressure when the gauge is exposed to the atmosphere, and is usually what most pressure gauges display, represented by "pb." 4. Vacuum degree is the absolute value of negative gauge pressure when the absolute pressure is lower than atmospheric pressure, often indicated by "pz." 5. Differential pressure is the difference between two pressures within a system, and is frequently used in industrial applications for flow or level measurement indirectly.

Pressure plays a crucial role in many industrial processes. Many production systems require specific pressure conditions to achieve desired outcomes, making pressure monitoring essential for safety and efficiency. Accurate pressure detection and control are vital components in ensuring the economic viability and safe operation of industrial facilities. Whether in chemical processing, power generation, or manufacturing, understanding and managing pressure is fundamental to operational success.
