The Sensitive Single Pole Switches can be used as Pressure or Vacuum Switches (from .25 inches of water to 45 inches of water) or as Differential Pressure Switches. Making the switch function as a Differential Pressure switch, or a Comparative Pressure switch, would require a two source system. The switch would actuate when the gap between the two sources of pressure is further apart than the set point of the switch. The switch responds to rapid pulsing and the gold plated silver contacts will handle low level switching currents.
Adjustable air bleeds can be supplied on either side of the diaphragm for pulse sensing applications involving safe edges or bellows.
