Differential pressure switches are an important tool for facilities management and are used to control the flow of air and liquid in various systems. In this blog, we’ll provide an overview of what a differential pressure switch is, what it is used for, and how it works.
What is a Differential Pressure Switch?
A differential pressure switch is a device used to control the pressure within a system. It works by monitoring the pressure difference between two points and activating when the pressure difference reaches a preset level. Differential pressure switches are commonly used in industrial and commercial applications, such as air conditioning, heating, and ventilation systems.
What is a Differential Pressure Switch Used For?
Differential pressure switches are commonly used in facilities management for a variety of purposes, including:
• Monitoring air flow in ventilation and HVAC systems
• Controlling liquid levels in tanks and reservoirs
• Monitoring pressure levels in pipes and tubing
• Adjusting the pressure of pumps and fans
• Detecting system malfunctions
• Regulating fuel and steam delivery
How Does a Differential Pressure Switch Work?
A differential pressure switch works by monitoring the pressure difference between two points in a system and triggering an alarm or other action when the pressure difference reaches a preset level. This is done by comparing the pressure in two points in the system and activating a switch when the pressure difference reaches the preset level.
The switch can be programmed to activate at a range of different pressure levels, allowing it to be used in a variety of different applications.
Conclusion
Differential pressure switches are a useful tool for facilities management, as they can be used to monitor and control pressure levels in various systems. Differential pressure switches are used to monitor air flow, liquid levels, pressure levels, and system malfunctions, as well as to regulate fuel and steam delivery. They work by comparing the pressure in two points in the system and triggering an alarm or other action when the pressure difference reaches a preset level.
