Designed for sensing the flow of air in duct work, this Johnson Controls(R) compact differential air pressure switch is ideal for use in detecting icing of air conditioning coils and initiation of the defrost cycle. This durable switch can sense a change in the differential pressure (either velocity pressure or pressure drop across a fixed restriction in the duct) as air flow in the duct changes. Model has an easy-to-read point scale and allows a number of mounting options. Probe is not included. Suitable for use in residential, light commercial mid-efficiency furnaces, and direct digital control (DDC) applications.
