Pressure Switches DBL-205

The DBL Series Differential Pressure Switches are adjustable vacuum, pressure and differential pressure switches designed for both HVAC and Energy Management Applications. They can be used to sense either positive or differential air pressures. The DBL pressure switches are compact and easy to install, since they have an internal, linearly scaled setpoint knob with an adjustable switching differential. They will save installation time and money due to the ease of the calibration and adjustment procedures. A manometer is not necessary but can be used to verify the overall operation of the switches. The DBL Series Pressure Switches are available in ranges from 0.08 to 0.8” W.C. all the way up to 2.0 to 10.0” W.C.. They will automatically reset and have field adjustable setpoints and switching differentials. Each unit contains (1) SPDT contact rated for 250 VAC @ 1.5 Amps. All wiring connections are to be made with spade connectors and a maximum wire size of 16 AWG. The DBL Series pressure switches contain a 1/2” conduit connection and are mounted in a NEMA 4 transparent synthetic housing.
