Description
Schneider Electric (Square D) 9037HG33RZ20 2-1/2″ Float Switch with Viton Pack operates as a mechanical system for tank and vessel liquid level monitoring in HVAC systems. The system operates through the buoyant force of float that moves the switch at specific points when the liquid level changes. The switch activation leads to the activation of equipment such as pumps or alarms to achieve proper liquid levels. This float switch operates primarily as an overflow prevention part and pump dry-running protector in condensate pans of large air conditioning units and humidifiers. The Viton seal enables performance in demanding HVAC conditions through its ability to resist various chemicals and high temperatures which extends durability.
