Introduction to Differential Pressure Gauge

A differential pressure gauge is an instrument used to measure the difference between two pressure points in a piping system, tank, or gas/liquid environment.

This device is widely used for:

• Monitoring filter contamination (filter clogging level)
• Measuring liquid level in closed tanks
• Monitoring room pressure in cleanrooms (positive/negative pressure)
• Measuring airflow or liquid flow in industrial systems
• Controlling pump and HVAC systems

Wide Measuring Range & High Durability

Differential pressure gauges are available in a very wide range:

• From 0 ~ 0.5 mbar
• Up to 0 ~ 1000 bar

They use various sensing mechanisms such as:

• Diaphragm element
• Bourdon tube
• Capsule element

With overload protection up to 400 bar, ensuring safe operation in harsh industrial environments.

Working Principle

The differential pressure gauge operates based on the comparison of two pressure values:

• When both pressures are equal → no movement occurs
• When there is a difference → the internal mechanism moves and displays the differential value

The mechanical movement system translates the pressure difference into a readable value on the dial.

Applications

Differential pressure gauges are widely used in many industries:

• HVAC systems (central air conditioning)
• Cleanrooms
• Pharmaceutical industry
• Food & beverage industry
• Electronics manufacturing
• Aerospace industry
• Environmental engineering
• Water and gas treatment systems

👉 In cleanroom applications, differential pressure gauges help maintain pressure control between zones, preventing dust and contaminants from entering controlled environments.
