What is the level switch?

level switch, also commonly referred to as a float switch, is a device that senses the liquid level in the water tank. It is a specialized type of pressure switch that is capable of sensing the pressure with the plastic tube. For example, in the sink, the plastic tube runs from the surface switch inside the control bracket and continues from the outside of the bathtub.

The plastic tube in the level switch is filled with air. In the example of the bath, the water enters the bathtub and some of them get into the plastic tube. The water in the plastic tube then rises and pushes the air inside the air. This in turn causes the air pressure to increase. Finally, the air pressure reaches the point at which the switch triggers.

The level switch is usually available in small and large sizes. In addition, these devices can range from simple to very complex designs. The simplest form of the level switch includes a mercury switch located inside the hanging -out. The more complex model uses complex sensors.

obeThe virtues are adjustable. It is also possible to buy a two -stage switch. This can be quite useful because it can prevent floods.

At the two -stage switch, the liquid in the object in the first phase is raised to the boot point. After activating the pump, the liquid will continue to rise if the pump is blocked or if it cannot function properly. In this case, the second phase of the switch will enter into force, turn off the pump, postpone the alarm or both.

level switch can also be universal enough to detect wet and dry conditions. In addition, it can detect liquid on the liquid interface and can determine whether the substance is foam, air or liquid.
