seelike RF-3001 Aquarium Pool Liquid Water Level Sensor Stainless Steel Float Switch alarms pumps 60mm Length

Description

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.
