Description
The Schneider Electric (Square D) 9037HW31 Closed Tank Float Switch is a liquid level detector used in mechanical and HVAC systems. It is mounted in equipment that requires condensate or other liquid containment, and its NEMA 4 enclosure rating offers water and dust resistance. The switch has a float-actuated component that switches as the liquid rises. It is a secure input in the control circuitry of the system, and it notifies the operating system that the liquid has reached a preset level, and it can take the necessary action.
