As the static pressure increases, #2 algorithm is applied to control the dampers. Differential Pressure Duct Sensors for VAV Systems Differential Pressure Flow VAV Sensors. HVAC systems, regardless of size, are designed to move a certain amount of air. Pressure sensors are installed on HVAC unit return and supply. An air switch senses positive, negative or differential air pressure and actuates an internal switch. For static pressure testing, make sure the manometer is equipped with two pressure ports. and display pressure to 1/100 of an inch. Switches are extremely reliable and cost-effective where the process variable need only be controlled within upper and/or lower bounds due to lower installed costs and much longer service life when compared with a transmitter of similar quality. Differential Pressure Switches Differential pressure switches are ideal process devices in various Industrial sectors. Static pressure is measured in inches of water column (“WC) and is the amount of pressure needed to displace one inch of water in a water manometer. SOR pressure switches are designed and offered with a number of agency approvals, housing enclosures and switching configurations to meet the demands of global markets.
