Reliable Low Pressure SensingDesigned for robust performance, this diaphragm-actuated pressure switch quickly detects system pressure drops within 10 milliseconds. Its compact size and reinforced plastic housing ensure adaptability and lasting durability in demanding environments such as industrial automation, HVAC, and fluid control.
Durable and User-Friendly DesignWith a mechanical life exceeding 100,000 operations and over 50,000 electrical cycles, this switch promises minimal maintenance. The manual set screw allows precise pressure adjustment within a 0.2-6 bar range, while direct threaded connection and IP65 rating ensure simple, secure installation-even in high-humidity and wet conditions.
FAQ's of Low Pressure Switch:
Q: How is the Low Pressure Switch installed in a system?
A: The Low Pressure Switch features a direct threaded connection with 1/4 inch BSP thread size. Simply screw it into the corresponding threaded port on your system, ensuring a tight seal to maintain IP65 protection. No specialized tools are needed beyond standard plumbing wrenches.
Q: What applications is this pressure switch best suited for?
A: This switch is ideally suited for industrial automation, HVAC systems, fluid control systems, and pump protection, where reliable low-pressure detection and rapid response are critical to system safety and efficiency.
Q: When should manual pressure adjustment be performed, and how is it done?
A: Manual pressure adjustment is required when calibrating the switch to your system's pressure requirements or after changes in system configuration. Adjustments are made using the accessible set screw until the switching threshold matches your desired pressure within the 0.2-6 bar range.
Q: Where can this switch be used safely given environmental conditions?
A: Thanks to its reinforced plastic housing and IP65 rating, the switch can be safely used in dusty or humid environments with ambient humidity up to 95% (non-condensing) and temperatures ranging from -10C to 80C.
Q: What are the main benefits of the silver alloy contacts and robust housing?
A: Silver alloy contacts provide superior conductivity and wear resistance, extending electrical life beyond 50,000 cycles. The reinforced plastic housing improves mechanical life and protects the switch from dust and water ingress, ensuring long-term reliability.
Q: How does the switch contribute to pump and system protection?
A: The pressure switch rapidly detects any drop below the set pressure and provides an SPDT output to control pumps or alert systems, preventing damage due to low-pressure conditions and maintaining optimal operation of fluid control systems.
