Dual Setpoint Differential Pressure Switch

 

The Cleveland Controls Model DDP-109 Dual Setpoint Differential Pressure Switch provides dual switch action for HVAC and energy management applications. Two separately operated, independently adjustable SPDT snap-acting switches are mounted on a common foot bracket. Since the switches are set independently, an adjustable "deadband" can be established for control circuits requiring both high and low actuation points. The unit can measure differential pressures up to 2" W.C.
