Pressure Gauges FAQ Section

Q: What are the main types of pressure gauges available?

A: The most common types of pressure gauges include:

• Bourdon tube gauges (most common for industrial use)
• Diaphragm gauges (for low pressure or corrosive media)
• Capsule gauges (for very low pressure measurements)
• Digital pressure gauges (with electronic displays)
• Differential pressure gauges (measuring difference between two pressures)

Each type has specific applications where it performs best.

Q: How often should pressure gauges be calibrated?

A: Pressure gauges should be calibrated:

• Annually for general industrial applications
• Every 6 months for critical processes
• After any mechanical shock or exposure to extreme conditions
• When readings appear inconsistent or questionable

More frequent calibration may be required by industry standards or quality control procedures.

Q: What's the difference between liquid-filled and dry pressure gauges?

A: Liquid-filled pressure gauges contain glycerin or silicone oil which provides several benefits:

• Dampens vibration and pulsation for clearer readings
• Lubricates internal components for longer life
• Prevents condensation in humid environments
• Protects against freezing in cold conditions

Dry gauges are simpler and typically less expensive, but may show needle fluctuations in vibrating environments.

Installation and Maintenance Tips

Proper installation and maintenance ensure optimal performance of your pressure gauges:

1. Mount gauges vertically for most accurate readings
2. Use appropriate thread sealant for connections
3. Install isolation valves for easy maintenance
4. Protect from extreme temperatures when possible
5. Clean gauge faces regularly for clear visibility
6. Check for leaks at connection points periodically
