Dwyer Instruments ADPS-03-2-N Adjustable Differential Pressure Switch 0.2-2" WC

The Dwyer ADPS-03-2-N Adjustable Differential Pressure Switch functions as an essential control mechanism for HVAC system pressure monitoring operations. The switch functions between 0.20 to 2.00 inches of water column pressure by using a silicone diaphragm to sense pressure changes which enables safe and efficient system operation. The part serves applications well by monitoring air filters while controlling fan speeds and maintaining proper ventilation duct airflow. The part detects pressure differences between points and activates alarms or shuts down systems when thresholds are reached to stop damage from pressure or airflow problems.
