Understanding the difference between a pressure switch and a vacuum switch is crucial for selecting the right equipment for your industrial needs.
5 Key Differences Explained
1. Type of Pressure Measured
A pressure switch detects and reacts to increases in pressure. A vacuum switch monitors and responds to decreases in pressure, often referred to as vacuum or negative pressure.
2. Operational Mechanism
Pressure Switches:
- Operate by sensing changes in pressure that act upon a diaphragm.
- When the pressure exceeds a predetermined setpoint, the diaphragm compresses a calibrated spring, triggering the switch to change its state.
- This can either close normally open (NO) electric contacts or open normally closed (NC) contacts.
Vacuum Switches:
- Designed to detect changes in negative pressure.
- When the vacuum level reaches a preset sensitivity, the diaphragm in the switch moves, opening or closing the attached circuit.
- This action can power on or off a device.
3. Direction of Pressure Change
Pressure switches are activated by an increase in pressure. Vacuum switches are activated by a decrease, or an increase in vacuum.
4. Common Applications
Pressure Switches:
- Typically used in environments where pressure needs to be regulated.
- Common applications include air compressors, furnaces, and water pumps.
Vacuum Switches:
- Employed in systems where vacuum levels are critical.
- Common applications include vacuum pumps, electric heaters, and transmission systems.
5. Selection Criteria
The choice between a pressure switch and a vacuum switch depends on the specific requirements of the system in which they are to be installed. Each type of switch is designed to monitor and respond to a particular type of pressure change, ensuring the proper functioning of the equipment they are integrated with.
