Industrial hydraulic systems are widely used in construction machinery, metallurgy, machine tools, mining, petrochemicals and other fields, serving as the core power source for industrial production. However, in actual operation, pressure monitoring of hydraulic systems often faces numerous pain points, such as inaccurate pressure gauge readings caused by vibration, equipment damage due to medium corrosion, compromised production quality from insufficient precision, and shortened equipment service life in harsh environments. These pain points not only affect the normal operation of hydraulic equipment but also may increase the production risks and operation and maintenance costs of enterprises. In contrast, high-precision shock-resistant stainless steel pressure gauges address various pain points in industrial hydraulic scenarios in a targeted manner and have become an ideal solution to industry challenges by virtue of their exclusive adaptive advantages.

During the operation of industrial hydraulic equipment, components such as hydraulic pumps, motors and hydraulic cylinders generate continuous vibration, and the vibration frequency of some equipment can reach several hundred hertz. The internal movement of ordinary pressure gauges consists of precision components such as gears and hairsprings. Vibration causes friction and loosening between these components, leading to pointer jitter and excessive reading deviations. In severe cases, it may even result in movement damage and pressure gauge scrapping. Especially in high-frequency vibration scenarios such as construction machinery and mining equipment, the service life of ordinary pressure gauges is often less than 3 months, requiring frequent replacement. This not only increases operation and maintenance costs but also may cause interruptions in pressure monitoring due to untimely replacement, triggering equipment failures.

To address this pain point, high-precision shock-resistant stainless steel pressure gauges adopt an exclusive shock-resistant structural design. Their interior is filled with silicone oil or glycerin damping fluid, which has a good buffering effect. It can effectively absorb the impact force generated by equipment vibration, reduce the shaking of movement components, ensure stable pointer operation and clear and accurate readings. At the same time, the pressure gauge movement adopts a reinforced precision structure, and components such as gears and hairsprings are made of high-strength wear-resistant materials and processed through special heat treatment processes, which improves the vibration resistance and service life of the components. Even in high-frequency vibration hydraulic scenarios, it can maintain stable measurement performance with a service life 3 to 5 times that of ordinary pressure gauges, greatly reducing the operation and maintenance costs of enterprises.

Some hydraulic oils used in industrial hydraulic systems contain corrosive additives. Meanwhile, heat is generated during the operation of hydraulic equipment, leading to an increase in system temperature, and the temperature of hydraulic oil in some scenarios can exceed 150℃. Ordinary carbon steel or plastic pressure gauges are prone to rust, corrosion and aging of shell, joints and other components under the combined action of corrosive hydraulic oil and high-temperature environment, and even oil leakage and damage may occur. This not only affects the normal use of pressure gauges but also may pollute the hydraulic medium and damage other components of the hydraulic system.

High-precision shock-resistant stainless steel pressure gauges solve the problems of corrosion and high temperature in a targeted manner and are fully made of 304 or 316 stainless steel. 304 stainless steel has good corrosion resistance, high temperature resistance and mechanical strength, which can resist the erosion of ordinary hydraulic oil, water vapor, dust and other media. It has an adaptive temperature range of -40℃ to 120℃, meeting the usage requirements of most industrial hydraulic scenarios. On the basis of 304 stainless steel, 316 stainless steel is added with molybdenum element, which further improves its corrosion resistance and high temperature resistance with an adaptive temperature range of -40℃ to 150℃. It can be used in harsh hydraulic scenarios with corrosive hydraulic oil, high temperature and high pressure, such as hydraulic systems in the chemical and petroleum fields. The application of stainless steel not only effectively extends the service life of pressure gauges but also avoids pollution and damage to the hydraulic system caused by material aging and corrosion.

Industrial hydraulic systems have extremely high precision requirements for pressure control, and the precision requirements vary in different scenarios. For example, the pressure precision requirement of precision hydraulic machine tools needs to reach ±0.01MPa, and that of hydraulic forming equipment needs to reach ±0.05MPa. The precision grade of ordinary industrial pressure gauges is mostly Grade 1.0 or Grade 2.5, which cannot meet the measurement requirements of high-precision hydraulic scenarios. Excessive reading deviations may lead to unqualified product processing precision, equipment action failure, and even safety accidents such as pipeline burst and equipment damage.

High-precision shock-resistant stainless steel pressure gauges take high precision as their core advantage, with a precision grade of up to Grade 0.2 or Grade 0.4 and a minimum graduation value of 0.01MPa. They can accurately capture the pressure changes
