SEN-PPI150 PP vertical magnetic water level switch liquid level switch float level switch

A float switch may be a sort of level sensor, a tool wont to detect the extent of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices.

One sort of float switch uses a mercury switch inside a hinged float. Another common type is a float that raises a rod to actuate a microswitch. One pattern uses a reed switch mounted during a tube; a float, containing a magnet, surrounds the tube and is guided by it. When the float raises the magnet to the reed switch, it closes. Several reeds are often mounted within the tube for various level indications by one assembly. Some float switches contain a two-stage switch. As liquid rises to the trigger point of the primary stage, the associated pump is activated. If the liquid continues to rise (perhaps because the pump has failed or its discharge is blocked), the second stage are going to be triggered. This stage may cut the source of the liquid being pumped, trigger an alarm, or both.

Where level must be sensed inside a pressurized vessel, often a magnet is used to couple the motion of the float to a switch located outside the pressurized volume. In some cases, a rod through a packing box are often wont to operate a switch, but this creates high drag and features a potential for leakage. Successful float switch installations minimize the chance for accumulation of dirt on the float that might impede its motion. Float switch materials are selected to resist the deleterious effects of corrosive process liquids. In some systems, a properly selected and sized float are often wont to sense the interface level between two liquids of various density.
