Cleveland Controls NS2-1287-00 Pressure Switch

The Cleveland Controls NS2-1287-00 Pressure Switch is a high-performance air pressure sensing switch specifically engineered for modern HVAC systems and industrial process controls. This NS2 series diaphragm switch is designed to sense positive, vacuum, or differential air pressure, providing critical feedback to furnace control boards and industrial boiler systems. With its robust glass-filled polycarbonate housing and SPDT electrical contacts, the NS2-1287-00 offers a reliable set point for proving airflow and monitoring filter status in demanding mechanical room environments. This model is a direct replacement for many OEM pressure switches found in commercial compressors and pumps, ensuring that your equipment maintains peak system efficiency and meets safety requirements without unnecessary downtime. The field-proven design provides a stable trip point that prevents short-cycling of burners and induction motors by accurately detecting differential pressure changes.

Veteran Technician Benefits:

• Universal Mounting Compatibility: The NS2-1287-00 fits standard footprint layouts, making it the go-to HVAC replacement part for onsite repairs.
• High-Sensitivity Diaphragm: Precision-molded silicone diaphragm responds to minute pressure fluctuations, ensuring accurate air pressure monitoring.
• Durable Brass Fittings: Standard 1/4 inch compression or hose barb connections provide a secure, leak-proof seal for industrial process control tubing.
• Snap-Action Switching: The industrial grade internal switch mechanism prevents contact arcing and ensures a clean signal to the controller.

Common Questions:

What is the set point range for the NS2-1287-00?
This specific Cleveland Controls pressure switch is factory-set for precision accuracy, though the NS2 series typically handles ranges from 0.05" w.c. to 12.0" w.c. depending on the specific orifice and spring configuration.

Can this be used for both positive and negative pressure?
Yes, the dual-port design allows for differential pressure sensing, meaning it can monitor the pressure drop across a filter or the static pressure in a supply duct.

Is this switch compatible with high-temperature flue gases?
The NS2-1287-00 is rated for standard ambient and process air temperatures typical of industrial HVAC applications. Always verify that the sensing line temperature does not exceed the maximum housing rating at the point of entry.
