Cleveland Controls NS2-0111-00 Pressure Switch
The Cleveland Controls NS2-0111-00 is an essential OEM air flow pressure sensing switch specifically calibrated at .45" w.c. for AAON equipment and high-performance industrial HVAC systems. This differential pressure switch utilizes a high-grade silicone diaphragm and a glass-filled polycarbonate housing to provide superior stability in building automation environments. As a veteran-preferred HVAC pressure switch, it features an integral SPDT switch mechanism capable of handling 1.2A at 24 VAC/VDC, making it ideal for monitoring positive, negative, or differential air pressure in sensitive ductwork applications. The inclusion of a compression fitting ensures a secure, leak-free connection to 3/16" ID tubing, maintaining the precise pressure setpoint required to prove fan operation or filter status. Whether you are performing a furnace pressure switch replacement or upgrading a commercial air handler, the NS2-0111-00 offers the narrow switching differential and low setpoint tolerance necessary to prevent short-cycling and ensure equipment safety.
- AAON Compatibility: Factory-calibrated to .45" w.c. for seamless integration with AAON and industrial machinery.
- Reliable Sensing: Equipped with a silicone diaphragm that maintains accuracy across a temperature range of -40° to 190°F.
- Versatile Wiring: Features three 1/4" 90-degree quick-connect terminals for SPDT, NO, or NC configurations.
- Rugged Enclosure: The NEMA 1 rated glass-filled polycarbonate housing provides excellent contaminant protection and durability.
- Pneumatic Security: Built-in compression fittings eliminate vacuum leaks common with standard barbed ports in high-vibration environments.
Common Questions
What is the purpose of the .45" w.c. setpoint on this switch?
The .45" water column setpoint is the specific trip point used to verify that a blower motor is moving sufficient air or that a heat exchanger is maintaining the correct vacuum. In many AAON units, this specific rating is critical for the safety circuit to allow the ignition sequence or cooling stages to proceed.
Can the NS2-0111-00 be used for both positive and negative pressure?
Yes, this switch is designed to sense positive, negative, or differential air pressure. Connect your sample line to the black (P1) port for positive pressure or the gray (P2) port for negative/vacuum pressure sensing.
Is this switch field-adjustable?
While the NS2 series is adjustable, the NS2-0111-00 is factory-set for precision. If adjustment is required for a custom application, it can be fine-tuned using a 7/32" hex wrench, though a manometer is required to verify the new setpoint accurately.
