Beyond Pressure Monitoring: Using Differential Pressure Switches as Vacuum Switches
When engineers think of differential pressure switches, they often associate them with monitoring pressure differences between two points in a system. However, these versatile instruments can do much more.
A differential pressure switch can be used to detect the difference between:
- Two positive pressures
- Two negative pressures
- One positive and one negative pressure
But that's not all.
By simply venting the high-pressure port to the atmosphere, a low-range differential pressure switch can function as a vacuum switch. This allows the switch to monitor vacuum conditions accurately and reliably without requiring a dedicated vacuum sensing device.
This versatility is one of the reasons why Orion Instruments' Differential Pressure Switches are widely used across industrial applications. Designed for reliable performance and precise switching, they provide a practical solution for both differential pressure and vacuum monitoring requirements.
Why Use a Differential Pressure Switch as a Vacuum Switch?

A single instrument can serve multiple applications, reducing inventory and procurement costs.
Reliable Vacuum Detection
Low-range differential pressure switches provide precise switching points for vacuum monitoring in industrial processes.
Simple Installation
With the high-pressure port vented to atmosphere, the switch can be quickly adapted for vacuum sensing applications.
Versatile Applications
Commonly used in:
- Vacuum pumps
- Filtration systems
- HVAC equipment
- Process industries
- Packaging and material handling systems
One Instrument. Multiple Possibilities.
The ability to function as both a pressure switch and a vacuum switch makes differential pressure switches a practical choice for industries seeking flexibility, reliability, and efficiency.
Orion Instruments' Differential Pressure Switches are engineered to deliver dependable performance in demanding industrial environments, helping operators monitor critical process conditions with confidence.
