Capsule Pressure Gauges: Precision Measurement for Low-Pressure Applications

In industries where low-pressure measurement is critical, capsule pressure gauges provide an accurate and reliable solution. These specialized devices excel in monitoring small pressure changes, making them an essential tool for various applications.

What is a Capsule Pressure Gauge?  

A capsule pressure gauge is a mechanical device designed to measure low-pressure ranges, typically below 600 mbar. Unlike standard pressure gauges, these gauges use a capsule element to detect minute pressure changes with high sensitivity.

The capsule element consists of two thin, corrugated metal diaphragms soldered or welded together. When pressure is applied, the capsule expands or contracts, and this movement is translated into a readable value on the gauge dial.

Key Features of Capsule Pressure Gauges  

- High Sensitivity: Designed for precise measurement of low-pressure ranges.  

- Compact Design: Easy to install in limited spaces.  

- Material Versatility: Capsule elements are available in materials like stainless steel, Monel, or brass to suit different media.  

- Accuracy: Provides precise readings, often meeting industrial standards for low-pressure applications.  

Applications of Capsule Pressure Gauges  

Capsule pressure gauges are widely used across industries that require accurate low-pressure monitoring:  

1. HVAC Systems: Measuring airflow and pressure in ducts and filters.  

2. Medical Equipment: Monitoring gas flow in ventilators and oxygen systems.  

3. Industrial Processes: Tracking pressure in gas lines and low-pressure tanks.  

4. Laboratories: Measuring pressure in controlled experiments and setups.  

Advantages of Using Capsule Pressure Gauges  

- Accurate Low-Pressure Measurement: Ideal for applications where precision matters.  

- Durability: Built to withstand various environmental conditions and media.  

- Ease of Maintenance: Simple design ensures reliability with minimal upkeep.  

Conclusion  

Capsule pressure gauges are indispensable for industries requiring precise low-pressure measurement. Their unique design and reliable performance make them a top choice for critical applications, ensuring efficiency and safety in operations.
