AIRFLOW SWITCH FOR AIR DUCTS Abstract of the Disclosure An airflow switch for sensing airflow or lack OF same in an air duct comprising a housing base, mounting in side-by-side relation an adjustable range spring and a single-pole double-throw snap action microswitch, with the microswitch having its actuating lever operated by a bellcrank type input lever against an adjustable spring bias applied … WC) 0.06 to 0.6, SPST Switch Type, Pressure Setting Range (In. By accepting cookies you can optimize your browsing experience. The electrical contacts of the switch are closed upon sensing positive air pressure generated by the blower. Static pressure measurements in the 4 to 10-inch range are part of the diagnostics. Five pressure range increments are available. The differential pressure switch is characterised by its simple mounting and high reliability. These sensors can be used to measure static pressure in a large range of liquids and gases. High quality elements guarantee long stability and wide operating ranges for both humidity and temperature. Grainger's got your back. The pressure switch is designed for surface wall mounting or installation into air ducts on the mounting bracket with two Ø 5 mm openings located at 40 mm center-to-center distance. 96 $57.99 $57.99.
