What Exactly is a Capsule Pressure Gauge and How Can It Benefit Your System?
2025-08-27
If you're involved in industrial processes, HVAC, hydraulic systems, or any application where precise pressure measurement is critical, you've likely encountered the term "Capsule Pressure Gauge." But what sets it apart from other pressure instruments? Simply put, a capsule pressure gauge is designed for measuring low pressures of dry gases, particularly when high accuracy is required in environments with minimal pressure fluctuations. Its unique capsule element, typically consisting of two thin, concentric diaphragms welded together, makes it exceptionally sensitive to slight pressure changes.
At Changshu Herun Import&Export Co., Ltd., we specialize in providing high-quality capsule pressure gauges that meet rigorous industrial standards. Our products are engineered for durability, precision, and reliability, ensuring optimal performance in your specific applications.

Capsule Pressure Gauge FAQ Common Questions
1. What is the typical application of a capsule pressure gauge?
Capsule pressure gauges are primarily used for measuring low pressures of dry, non-corrosive gases. They are common in HVAC systems, medical devices, environmental testing equipment, and pneumatic controls where high sensitivity to slight pressure changes is required.
2. How do I maintain a capsule pressure gauge to ensure longevity?
Regular maintenance includes checking for calibration drift every 6-12 months, ensuring the gauge is free from dust and moisture, and verifying that connections are tight and leak-free. For gauges filled with fluid, inspect for bubbles or discoloration, which might indicate a need for service. Avoid exposing the gauge to overpressure or temperatures outside its specified range.
3. Can a capsule pressure gauge be used with liquids or corrosive media?
No, capsule pressure gauges are generally designed for dry, clean gases only. The sensitive capsule element can be damaged by moisture, particulates, or corrosive substances. If your application involves liquids or aggressive media, consider a diaphragm seal or a different type of pressure gauge designed for such conditions.
