Cleveland Controls NS2-0548-00 Pressure Switch
The Cleveland Controls NS2-0548-00 Air Flow Sensing Switch is a high-precision differential pressure switch engineered for critical HVAC monitoring. This unit is factory-calibrated at a 0.98" w.c. set point, providing reliable air pressure differential detection in furnaces, air handlers, and ventilation systems. Built with a rugged glass-filled polycarbonate housing and a high-grade silicone diaphragm, the NS2-0548-00 ensures long-term stability and consistent switching performance under varying thermal conditions. This model includes a versatile mounting bracket for secure integration into both OEM and field-service applications.
Designed for professional contractors, this HVAC pressure switch features 1/4" quick-connect terminals and supports a variety of sample line connections. It is capable of sensing positive, negative, or differential pressure, making it an essential component for proving airflow and maintaining system safety. The compact footprint facilitates installation in tight equipment cabinets, while the snap-acting switch provides a definitive electrical response, rated for pilot duty at 24V, 120V, and 277V AC. When replacing a failed draft inducer switch or airflow prover, the NS2-0548-00 offers the exact specifications required to restore efficient and safe operations.
Key Benefits
- Precise Factory Calibration: Pre-set at 0.98" w.c. to ensure accurate airflow sensing without the need for field adjustment.
- Enhanced Durability: Constructed with a contaminant-free silicone diaphragm and polycarbonate body for 100,000+ cycle life.
- Seamless Installation: Integrated mounting bracket and color-coded ports (Black for High/Positive, Gray for Low/Negative) simplify labor.
- Broad Compatibility: Electrical ratings up to 15 Amps non-inductive and 300 VA pilot duty make it suitable for diverse HVAC systems.
- System Security: Accurately triggers safety shutdowns if airflow drops below required thresholds, protecting critical heating components.
Common Questions
Is the set point on the NS2-0548-00 adjustable?
No, this specific model is a factory-calibrated, non-adjustable switch. For field-adjustable needs, see the ANS2 series; however, for OEM replacements, maintaining the fixed 0.98" w.c. set point is critical for safety compliance.
What tubing is recommended for the air sampling ports?
The ports are designed for use with 3/16" or 1/4" I.D. flexible tubing. Ensure the tubing material is compatible with the operating temperature range of -40°F to 190°F.
Can this switch be mounted in any orientation?
For maximum accuracy relative to the factory set point, it is recommended to mount the switch with the diaphragm in a vertical plane. Horizontal mounting may cause a slight shift in the actuation point.
