VACUUM PRESSURE GAUGE | PM-E.VN

What Is a Vacuum Pressure Gauge?

A vacuum pressure gauge is a device used to measure negative pressure in vacuum systems or environments where the pressure is lower than atmospheric pressure.

This device is also known as a negative pressure gauge and is commonly used to monitor vacuum conditions in industrial systems, laboratories, and production lines.

Typical measurement ranges include:

0 bar to -1 bar
Depending on technical requirements, gauges can be designed with various pressure ranges and connection types.

Digital Vacuum Pressure Gauge

Digital vacuum gauges are used in systems requiring high precision.

Key advantages:

• Clear LED display
• High accuracy
• Robust design
• Easy readability
• Supports pressure unit conversion

Common supported units:

• Bar
• PSI
• MPa
• kPa

These devices are suitable for laboratories, automation systems, and applications requiring precise pressure control.

Operating Principle

When system pressure drops below atmospheric pressure, the internal sensing element responds to pressure changes.

For mechanical gauges, the Bourdon tube deforms and transmits motion to the pointer.

For digital gauges, the pressure sensor converts the signal into electronic data displayed on an LED screen.

Industrial Applications

Vacuum pressure gauges are used in many fields, including:

• Vacuum pump systems
• Vacuum packaging machines
• Laboratory equipment
• Food industry
• Pharmaceutical industry
• HVAC systems
• Electronics manufacturing
• Industrial production lines
• Gas treatment systems

These devices play a crucial role in monitoring and maintaining stable vacuum conditions in operating systems.
