Liquid Level switch

This level switch is also called Float sensor, liquid level sensor, reed switch etc.

They are used wherever it is necessary to control and regulate the level of liquids (e.g. water, oil, etc.). The sensor has a float equipped with a magnet, which moves vertically along the guide tube under the influence of the buoyancy force of the liquid, causing the reed switch located in the tube to short circuit or open. They are usually mounted in the bottom or lid of the tank, so they can be used to control the lower or upper level of the liquid. They are made of stainless steel and can be used in a wide range of temperatures.
