⚙️ Mechanism of Operation and Types of Pressure Gauges

Basic Types

Industrial pressure gauges rely on several technologies. The most common type is the Bourdon Tube Gauge, suitable for medium and high pressure. Other types include:

Type	Application
Bourdon Tube Gauge	Medium and high pressure (most common)
Diaphragm Gauge	Low pressures
Capsule Gauge	Very low pressures
Digital Gauge	High accuracy with electronic display
Manometer	Traditional device for measuring fluid pressure

Glycerin-Filled Gauges

These are mechanical gauges filled with glycerin to absorb vibrations and shocks, extending their lifespan and ensuring accurate readings. They are widely used in fire pumps and heavy industrial systems.

🔥 Applications of Pressure Gauges in Fire Protection Systems

Pressure gauges are used in several critical applications within fire protection systems:

Application	Description
Portable Fire Extinguishers	Mounted on the extinguisher to monitor internal pressure, ensuring readiness for immediate use
Fire Piping Networks	Measure pressure in sprinkler networks and fire hydrants to ensure adequate water reaches all points
Fire Pumps	Mounted on discharge and suction lines of main and jockey pumps for real-time pressure monitoring and performance adjustment – Glycerin-filled gauges are especially used due to their vibration resistance
