Cleveland Controls NS2-1291-00 Pressure Switch
The Cleveland Controls NS2-1291-00 Pressure Switch is a high-precision air pressure sensing switch designed for critical monitoring in industrial and commercial HVAC systems. Engineered with a factory-calibrated set point of .25" w.c., this unit ensures accurate detection of positive, negative, or differential pressure. It features a rugged, glass-filled polycarbonate housing and a high-stability silicone diaphragm, allowing it to maintain a narrow switching differential even in demanding environments with temperatures ranging from -40°F to 180°F. The integral snap-acting switch and color-coded ports (Black for High/Positive, Gray for Low/Negative) simplify field integration. Designed for differential pressure monitoring, the NS2-1291-00 provides a reliable safety interlock for furnace draft inducer motors and air proving applications, ensuring system integrity with a minimum life cycle of 100,000 operations at maximum rated electrical load.
Key Benefits- Precise Calibration: Factory-set at .25" w.c. for immediate installation without the need for field adjustment in matching OEM specifications.
- Durable Construction: The glass-filled polycarbonate body provides superior chemical resistance and structural stability across varying pressure loads.
- Versatile Sensing: Capable of sensing positive, negative, or differential air pressure, making it a universal choice for diverse pneumatic applications.
- Simplified Wiring: Features 1/4-inch 90-degree male quick-connect terminals for fast, secure electrical terminations.
- Environmental Resilience: Rated for wide-ranging operation, performing reliably from -40°F to 180°F.
What is the correct mounting orientation for this switch?
To maintain the factory-calibrated set point and avoid moisture buildup, the switch should be mounted with the diaphragm in a vertical plane. Mounting at an angle may shift the actuation point due to the effect of gravity on the internal diaphragm.
How do I identify the high and low pressure ports?
The ports are color-coded for technician convenience: the Black port is the high (positive) inlet (P1), and the Gray port is the low (negative) inlet (P2).
Can this switch be used for vacuum sensing?
Yes. For negative pressure (vacuum) only applications, connect the sample line to the Gray P2 port while leaving the Black P1 port open to the atmosphere.
