Description
The Schneider Electric (Square D) 9037HW32 Float Switch is a liquid level sensor that is used to measure and react to the level of fluid in condensate pans, tanks or drain lines in HVAC systems. It works up to 575 volts and has a float mechanism that closes or opens an electrical circuit depending on the presence of liquid. It is mounted in air handlers, rooftop units, or other equipment and is connected to control circuits to indicate high, or low liquid conditions. It is used in the system to avoid overflow by raising alerts or shutdown measures.
