Cleveland Controls AFS-145-045-A Sensing Switch
The Cleveland Controls AFS-145-045-A is a commercial-grade air pressure sensing switch specifically designed for proving airflow in package burners, furnaces, and high-efficiency HVAC systems. This differential pressure switch features a wide adjustable set point range of 0.05" ± 0.02" to 12" w.c., allowing for precise field calibration to meet strictly defined sequence-of-operation requirements. Built with a durable silicone diaphragm, the unit is compatible with air and combustion by-products that do not degrade silicone, ensuring long-term reliability in demanding exhaust or supply air environments. The SPDT contact arrangement (Single Pole Double Throw) provides versatile wiring options for normally open or normally closed circuits, and the integrated amber light offers immediate visual status indication for simplified troubleshooting. With 1/8" NPT sample line connectors, this switch integrates seamlessly into standard pneumatic tubing setups, maintaining a 15 Amp electrical rating at 277 VAC for heavy-duty pilot duty applications.
Key Benefits:- Precise Pressure Monitoring: Features a field-adjustable set point from 0.05" to 12" w.c. to accommodate a broad variety of static or differential air pressure applications.
- Contractor-Focused Design: Includes an amber light for quick visual confirmation of switch actuation, reducing diagnostic time during service calls.
- Industrial Durability: Constructed with a plated housing and a high-quality silicone diaphragm capable of operating in temperatures from -40°F to 180°F.
- Versatile Compatibility: Equipped with dual 1/8" NPT female connectors to enable positive, negative, or differential pressure sensing.
- High Electrical Capacity: Rated for up to 15 Amps, making it suitable for direct control or signaling in complex energy management systems.
- Can this switch be used to sense flue gas? Yes, the silicone diaphragm is designed to handle air and combustion by-products that are non-corrosive to silicone.
- How do I adjust the set point? The AFS-145-045-A features an adjustment screw under the enclosure cover; turn it clockwise to increase the pressure requirement and counter-clockwise to decrease it.
- What mounting position is required? For optimal accuracy at the lowest set points, the diaphragm must be mounted in a vertical plane.
- Does it work for both vacuum and pressure? Yes, by utilizing the "High" and "Low" ports, you can monitor positive, negative, or differential pressure as required by the equipment.
