Product Advantages

1. Sensitive Low Pressure Detection

The brass capsule element is designed to respond to small pressure variations encountered in low-pressure applications requiring stable mechanical indication.

2. EN 837-3 Design Construction

The gauge structure follows internationally recognized capsule pressure gauge design requirements to support consistent performance characteristics.

3. Front Zero Adjustment

The adjustable pointer mechanism allows convenient correction during inspection and maintenance procedures.

4. U-Clamp Surface Mounting

The mounting arrangement simplifies installation on panels and equipment housings where front accessibility is preferred.

5. Suitable for Dry Gas Applications

Designed specifically for non-aggressive gaseous media commonly encountered in laboratory, medical and environmental monitoring systems.

Working Principle

The capsule sensing element consists of formed diaphragms joined together to create a pressure-responsive chamber. Small pressure changes cause elastic movement of the capsule, which is transmitted through the movement mechanism to drive the pointer and indicate the corresponding pressure value on the dial.

How to Select a Capsule Pressure Gauge

• Select a measuring range where normal operating pressure remains within 30%–70% of full scale.
• Verify media compatibility with brass capsule elements.
• Confirm mounting requirements, including U-clamp or panel installation.
• Choose the appropriate process connection according to equipment specifications.
• Consider ambient conditions such as temperature and vibration levels.

Installation Recommendations

• Ensure the gauge is mounted securely using the designated U-clamp assembly.
• Avoid excessive tightening of process connections.
• Install in locations that permit easy visual inspection.
• Protect the instrument from excessive vibration when necessary.
• Operate only within specified pressure and temperature limits.
