It may be used to … As pressure increases, available differential increases as well. The switch is actuated by a difference in pressure between the two sensing elements. When the differential pressure exceeds your setpoint, the switch is activated. Often used with ovens, dryers, and HVAC systems, these switches detect small differences in pressure. Pressure Switches Ashcroft®pressure switches are provided in a variety of configurations to meet most installation requirements in nearly every industry. The air differential pressure switch PSS-series is suitable for use in air conditioning systems to provide an indication of fan status or 'filter dirty'condition. Please click here for information on our company’s current status & how we’re responding to COVID-19. In differential adjustment, the cut-in pressure can be increased or decreased on the pressure switch, changing the pressure differential. The LF31 is a favorite with leading manufacturers of gas-fired warm air furnaces and water heaters. A differential pressure switch is designed to sense a difference in pressure between two pressure sources in the plant for control purposes. The contact points in the switch are usually rated for the amount of current they can carry. A wide variety of switches and circuit styles enables control functions needed for any system.
