When it comes to monitoring and controlling pressure in industrial systems, pressure gauges play a critical role. From manufacturing plants to oil refineries, water treatment units to HVAC systems, pressure gauges ensure safety, accuracy, and efficient system performance.

Understanding the different types of pressure gauges and their specific applications helps industries choose the right instrument for the right job.

What Is a Pressure Gauge?

A pressure gauge is an instrument used to measure the pressure of gases or liquids in a system. This reading ensures that processes run safely within their ideal pressure range, preventing equipment damage, leaks, and hazardous incidents.

1. Bourdon Tube Pressure Gauge

Description

The most widely used pressure gauge type. It uses a curved metal tube that straightens under pressure.

Applications

Oil & gas
Water treatment
Compressed air systems
Hydraulic machinery
General industrial use

2. Diaphragm Pressure Gauge

Description

Uses a flexible diaphragm for pressure measurement; ideal for corrosive or viscous media.

Applications

Chemical processing
Pharma
Food industry
Gas regulation
Corrosive fluid measurement

3. Capsule Pressure Gauge

Description

Two diaphragms welded together to measure only low gas pressures.

Applications

HVAC
Gas burners
Leak detection
Low-pressure gas systems

4. Differential Pressure Gauge

Description

Measures the difference between two pressure points.

Applications

Filter monitoring
Cleanroom management
Flow measurement
Hydraulic systems
Pump monitoring

5. Digital Pressure Gauge

Description

Electronic gauge offering high precision, data logging, and digital display.

Applications

Calibration labs
R&D
Precision manufacturing
Pharma sectors

6. Vacuum Pressure Gauge

Description

Used to measure pressure levels below atmospheric pressure.

Applications

Vacuum pumps
Packaging
Laboratories
Semiconductor processes

7. Absolute Pressure Gauge

Description

Measures pressure relative to a perfect vacuum.

Applications

Scientific research
Aerospace
Meteorology
Highaccuracy testing

8. Liquid-Filled Pressure Gauge

Description

Filled with glycerine/silicone to resist vibration.

Applications

Heavy machinery
Marine
Hydraulic systems
Compressors
