FAQ's of Differential Pressure Switch:

Q: How do I install the Differential Pressure Switch in my system?

A: You can install the switch using the included wall or panel mounting bracket. With screw terminal electrical connections, simply follow the supplied manual for step-by-step wiring and mounting procedures. Its universal orientation allows flexible placement in your setup.

Q: What is the benefit of adjustable hysteresis on this pressure switch?

A: Adjustable hysteresis lets users fine-tune the switch's response band, reducing unwanted toggling and increasing system stability-ideal for processes with pressure fluctuations, enhancing operational reliability.

Q: When should the Differential Pressure Switch be used in industrial applications?

A: This switch is recommended when precise monitoring and controlling of pressure differences between two points are needed, especially in HVAC systems, filtration processes, or fluid handling, to maintain optimal performance and safety.

Q: Where can this switch be installed for best performance?

A: Thanks to its IP65-rated, weatherproof aluminum enclosure and robust seals, the switch can be installed in both indoor and outdoor industrial environments where resistance to dust and moisture is required.

Q: What kind of electrical loads can this pressure switch manage?

A: The SPDT contacts support electrical loads up to 5A at 250VAC or 0.25A at 250VDC, making it suitable for controlling pumps, alarms, relays, or other automated devices in your system.

Q: How does the pressure switch ensure accuracy and repeatability?

A: It incorporates a precision-calibrated Bourdon tube sensor and is tested for an accuracy of 1.5% F.S. With repeatability within 1% FS, it consistently triggers at the set differential pressure points, ensuring reliable system operation.
