Square pressure switches are a common industrial device widely used for pressure control of gases and liquids. They typically have female threaded connections and multiple contact configurations for different application scenarios.
1. Female threaded connection
The square pressure switch's female thread design allows it to be easily connected to the piping system. This design not only simplifies the installation process, but also ensures a tight seal to prevent leakage. For example, some models of pressure switches feature a 1/4-inch FNPS female connection, which is suitable for a wide range of piping systems.
2. Contact Configuration
Square pressure switches are typically equipped with a variety of contact configurations, such as double-pole, double-throw (DPST) or normally open/closed contacts. These contact configurations allow the user to choose from a variety of control functions based on specific needs. For example, some models of pressure switches will automatically switch contacts when the pressure reaches a set point, thus controlling the start and stop of electrical equipment.
3. Selection Recommendations
When selecting a Square D pressure switch, users should consider several factors:
Pressure range: Make sure the pressure range of the switch meets the system requirements.
Contact type: Select the appropriate contact configuration for the control requirements.
Connection type: Confirm that the female thread specification matches the piping system.
By understanding these features and selection recommendations, users can better select and utilize square pressure switches for their specific applications.
