Supco Air Pressure Sensing Switch, Universal, 0.1 - 10 Inch WC, 14 Inch WC Maximum, SPDT, Barbed, 5 A, 277 VAC, 100000 Cycles, -40 to 190 deg F, 1/4 Inch x 0.032 Quick Connect, Glass Filled Polycarbonate Housing, Includes: Calibration Springs, Calibration Tool (Hex Wrench), Mounting Brackets and Orifice Flow

  • The new universal air pressure sensing switch has field adjustable set points using the included adjustment tool
  • The switch comes in a contractor kit that includes the hardware and replacement hose
  • Robertshaw┬« air pressure sensing switches, this switch is NEMA rated and is practically insensitive to temperature change with an operating range of -40 to 190 deg F
  • The available sensing probe kit works with the universal switch as well as the rest of the Robertshaw┬« air pressure switch products to provide a form fit extension from your air source to the switch, limiting the need to install the switch directly on the air source
  • Conditioned air filters that accumulate particulate matter used to sense the differential pressure or airflow drop across the filter
  • Defrost cycle is initiated by sensing differential pressure or airflow drop across the refrigeration coils when they ice
  • On gas fired units, the switch senses draft down from the blower; switch actuation allows ignition start-up or system shutdown upon insufficient draft
  • On air-supported structures and enclosures, sensing switches ensure proper inflation or internal pressure switch actuation controls the blower to maintain pressure
  • Exhaust fans and fume hoods employ switches to sense draft down from the exhaust fan switch actuation signals condition upon fan failure of insufficient draft
