Product Advantages

1. Enhanced Sensitivity for Low Pressure Measurement

Capsule elements provide improved responsiveness and readability within low-pressure ranges compared with conventional Bourdon tube designs. Capsule gauges are widely recognized as effective solutions for low-pressure gas measurement. 

2. Compact Installation Design

The 50mm dial and back mount arrangement facilitate easy integration into control panels and OEM equipment.

3. Dry Maintenance-Friendly Construction

The dry design eliminates the need for filling liquids, reducing maintenance complexity during normal operation.

4. Reliable Mechanical Operation

The gauge provides local pressure indication without requiring electrical power or electronic components.

Working Principle

The capsule element consists of two corrugated diaphragms sealed together to form a pressure chamber. When pressure is applied, the capsule expands or contracts proportionally to the pressure variation. This movement is transmitted through a mechanical linkage system to the pointer, enabling accurate low-pressure indication. Capsule gauges are intended specifically for gaseous media applications. 

How to Select a Capsule Pressure Gauge

• Confirm that the medium is dry and gaseous.
• Select a pressure range appropriate for the operating conditions.
• Choose back mount versions for panel installations.
• Verify thread compatibility with the existing system.
• Consider required accuracy classes for the application.

FAQ

What is a capsule pressure gauge used for?

Capsule pressure gauges are designed for measuring low-pressure gaseous media in HVAC, laboratory and industrial systems.

Can this gauge be used for liquids?

No. Capsule pressure gauges are generally intended for dry and non-corrosive gases only.

Why choose a capsule gauge instead of a Bourdon tube gauge?

Capsule gauges offer higher sensitivity and improved readability within low-pressure measurement ranges.
