Float level switch FQ-OV31

1.Special designed
2.Low cost
3.Simple installation
4.Wide application

5.Material:PP

Brief

The single unit or multiple reed switch units are housed tightly in stainless steel or engineering plastic stem, and the permanent magnet is sealed into the middle of the specified float ball(s). You can mount the float ball to penetrating through the stem, and then the liquid buoyancy will deliver the float ball up and down at the specified position by graduating rings
When the float internal magnet approaches the reed switch, it will actuate the reed switch contact point to create an open or close circuit. We can apply such on-off output signals to reach liquid level controlling and monitoring purpose
Features
Multiple points measuring, multiple level points are available for custom-built.
It is used the magnet to actuate the reed switch without any extra electric power source.
Each reed switch is durable for operation life reaching 2 million times.
All output signal wiring is simplified in same junction box (housing) to economize the external wiring construction
The housing protection rating up to IP65..
Rugged construction and multiple options for materials from engineering plastics as PVDF, PP, PVC, and stainless steels as SUS304, SUS316, float switches can be applied to versatile applications in chemical corrosion of acidity and alkalinity liquid, solvents or oil fuels.
The reed switch and lead wire are isolated absolutely with liquids. All stainless steel switches are applicable to high pressure and high temperature performances. .

Movement explaination:

When the float ball rises or falls with the liquid to the level of the switch, The magnetic force of magnet which inside of the float ball will cause the reed switch to turn ON. When the float ball move away from the reed switch, the reed switch will turn OFF.
