In the field of pressure measurement, shockproof pressure gauges and general pressure gauges differ significantly in structure and performance, leading to distinct application scenarios. A detailed comparison is outlined below:

1. Structural Differences

General pressure gauges feature a basic mechanical structure without internal filling media, typically with an IP40 protection rating for the housing. In contrast, shockproof pressure gauges are filled with damping fluids such as glycerin or silicone oil inside the housing, achieving a protection rating of IP54 or IP65 and often employing stainless steel materials for enhanced durability.

2. Performance Differences

General pressure gauges exhibit weak resistance to vibration and shock, with pointers prone to shaking or sticking. They are suitable only for non-corrosive media like water or air and operate within a limited temperature range. On the other hand, shockproof pressure gauges absorb vibrational energy, ensuring stable pointer readings. They can withstand corrosive media such as acids, alkalis, and salt spray. By utilizing different filling fluids, they can adapt to a wide temperature range of -40°C to 120°C.

3. Application Differences

General pressure gauges are commonly used in low-vibration civilian applications, such as water pipelines and indoor storage tanks. In contrast, shockproof pressure gauges are designed for industrial environments with high vibration levels, including engineering machinery, mining operations, and marine power systems.

4. Cost and Maintenance Differences

General pressure gauges have lower procurement costs but require maintenance every 3–6 months. Shockproof pressure gauges, while more expensive initially, offer lower failure rates, longer lifespans, and extended maintenance intervals of 6–12 months, providing better long-term cost-effectiveness.

Conclusion  

General pressure gauges are suitable for static or low-vibration environments and are cost-effective. Shockproof pressure gauges are engineered for high-vibration and corrosive industrial settings, offering enhanced durability and reliability. The choice between the two should be based on specific operating conditions, including vibration intensity, media characteristics, and environmental requirements.
