The DBL Series Differential Pressure Switches are general purpose pressure switches designed for both HVAC and Energy Management applications

  • These pressure switches can be used to sense positive, negative, or differential air pressures when used in conjunction with an DBZ-06, A/SPT or A/VPT Series sampling tube
  • The NEMA 3 (IP54) rated weather proof plastic enclosure contains an On/Off, single stage micro switch and two pressure chambers separated by a silicone diaphragm
  • The enclosure also contains a ½” conduit knockout and guards against accidental contact with the live switch terminal screws as well as the factory calibrated linear set point adjusting knob
  • The set point can be adjusted without comparing to a field gauge, manometer or magnehelic
