Introduction to Air Compressor Pressure Switches
Air compressors are vital tools in numerous applications, from powering pneumatic tools to maintaining industrial processes. A crucial component ensuring safe and efficient operation is the pressure switch. Understanding its role is paramount for maintaining optimal performance and preventing potential hazards.A pressure switch, specifically a 175 PSI pressure switch, acts as a critical regulator in an air compressor system.
It’s a safety device that monitors and controls the air pressure within the system, ensuring it doesn’t exceed a predetermined limit, preventing damage to the compressor and ensuring consistent output.
Understanding the Function of a 175 PSI Pressure Switch
A 175 PSI pressure switch is designed to automatically regulate the air pressure within a system. When the pressure reaches 175 PSI, the switch activates, initiating a shutoff mechanism to prevent further pressure buildup. Conversely, when the pressure drops below a predetermined lower limit (typically set by the manufacturer), the switch reactivates the compressor, maintaining the desired operating pressure.
This cyclical process ensures consistent air pressure, protecting the compressor and the equipment it serves.
Operating Principles of a Pressure Switch
Pressure switches employ a variety of mechanisms to detect and respond to pressure changes. A common mechanism involves a diaphragm or bellows that moves in response to the pressure exerted by the compressed air. This movement activates a switch, either mechanically or electronically, controlling the compressor’s operation. Different types of pressure switches use various methods, as detailed in the table below.
Comparison of Pressure Switch Types
The table below Artikels the key differences between common types of pressure switches:
| Type | Mechanism | Advantages | Disadvantages |
|---|---|---|---|
| Mechanical | Uses a diaphragm or bellows connected to a mechanical switch. | Relatively simple and inexpensive. | Less precise than electronic types, subject to wear and tear. |
| Electronic | Employs sensors and electronic circuits to detect pressure changes. | More precise and reliable than mechanical types, often more durable. | More complex and expensive than mechanical types. |
The choice of pressure switch type often depends on the specific application and desired level of precision. Mechanical switches are generally sufficient for basic applications, while electronic switches offer enhanced control and accuracy, ideal for critical environments or precision work.

Common Pressure Ranges
PSI pressure switches are designed to operate within a specific pressure range. This range ensures accurate control and prevents damage to the system. Typically, these switches operate in the range of 0 to 175 PSI, providing precise control over the air compressor.
Operating Pressure and Differential Pressure
The operating pressure for a 175 PSI pressure switch is typically set at 175 PSI, signaling the compressor to shut off when this pressure is reached. A critical aspect is the differential pressure. The differential pressure is the difference between the pressure at which the switch activates and the pressure at which it deactivates. This difference, while often small, ensures the system operates reliably.
For instance, a 2 PSI differential pressure means the switch activates when the pressure reaches 175 PSI and deactivates when the pressure drops to 173 PSI.
Sensing Mechanisms
Various sensing mechanisms are used in 175 PSI pressure switches. The most common involves a diaphragm or a bourdon tube that deforms in response to changes in pressure. This deformation is translated into an electrical signal, activating or deactivating the compressor. Other sensing mechanisms, while less common, include piezoelectric sensors, which convert pressure changes into electrical signals, offering high sensitivity and responsiveness.
Factors Influencing Accuracy and Reliability
Several factors affect the accuracy and reliability of a 175 PSI pressure switch. These include the quality of the sensing element, the accuracy of the calibration process, the environmental conditions, and the quality of the materials used in its construction.
