The Cleveland Controls NS2-1166-01 Air Proving Switch is used to check airflow in various HVAC systems. This switch makes use of differential air pressure to check proper airflow. This has two ports, one to measure positive pressure and the other to measure static pressure. When there is enough airflow, the pressure difference triggers an internal switch which gives an electrical signal. It can then be used to switch on or off other apparatus. This maintains the safety of operations for the heating and cooling equipment such as furnaces, unit heaters, rooftops, and other units. Advantages include protection against operation with inadequate airflow, correct combustion, and optimization of the system.
