seelike RF-OH21D Tank Liquid Water Level Sensor Horizontal P.P Black Float Switch NO NC

? A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or other device.
? Wires send an electric signal to the outside of the tank through the watertight seal, making these components essential for accurate monitoring or regulation of fluid levels in many contexts.
? They function as vertically mounted switches, with a doughnut-shaped floats rising and falling with the level of the liquid around stems, actuating reed switches inside the stems.
? Easily mounted through a horizontal NPT fitting or internal through-hole, these liquid level sensors offer superior dependability and economy.
? Combine two switches open (NO) or normally closed (NC) at different levels for high and low level sensing or pump control.
