Cleveland Controls NS2-3130-00 Switch

The Cleveland Controls NS2-3130-00 Air Flow Switch is an OEM air-pressure sensing switch designed for HVAC, combustion-air, and equipment safety applications where reliable proof of airflow or pressure is required.

The NS2 Series uses a glass-filled polycarbonate housing with a silicone diaphragm and an integral snap-action switch. Depending on the installation and pressure-port configuration, it can sense positive, negative, or differential air pressure.

The NS2 platform supports factory-calibrated fixed pressure settings within a range of approximately 0.05" w.c. to 10.0" w.c., with a maximum applied pressure of 14" w.c. It is designed for air and combustion by-products that are compatible with the switch materials.

Typical HVAC applications include fan proving, burner interlocks, inducer verification, airflow monitoring, and equipment safety controls.

Common Questions

What is the Cleveland Controls NS2-3130-00 used for?
It is used to detect or prove airflow and air pressure in HVAC and combustion equipment. Common applications include blower and fan proving, burner controls, inducer monitoring, and safety interlocks.

Can an NS2 switch detect both pressure and vacuum?
Yes. Depending on how the pressure connections are configured, NS2 Series switches can be applied to positive pressure, negative pressure, or differential-pressure sensing.

What pressure range does the NS2 Series cover?
Cleveland Controls specifies factory-calibrated fixed settings within approximately 0.05" w.c. to 10.0" w.c., depending on the exact model configuration.

Is every NS2 Series switch interchangeable?
No. The exact part number and configuration matter. Before replacing an existing switch, verify the pressure set point, electrical contact arrangement, mounting, pressure connections, and equipment model.
