Cleveland Controls NS2-0000-01 Adjustable Pressure Switch Field W/Bleed Hole 0.1"-10" WC

The Cleveland Controls NS2-0000-01 Adjustable Differential Pressure Switch with the purpose of use in HVAC systems. It works based on the pressure variation across a filter, damper, or any other component of the system. The feature known as Field W/Bleed Hole enables making changes to the pressure setpoint in the field without the use of special tools. This switch is especially handy where airflow applications are essential such as HVAC systems. It could be used to measure pressure across air filters and inform the user when the filters are filled to a level where they potentially compromise air quality and efficiency.
