Fine Tek Level Sensor


1.Mini Float Level Switch-FC/FD Series

Principle

When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch “snaps” the contact together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch does not touch. The circuit is open.

Features

  • Compact simple design and principle, high reliability, low price.

  • Over 30 kinds of materials & specifications are optional.

  • PP, PVDF, NYLON, POLYSULFONE materials are suitable for corrosive environment.

  • SUS304 / 316; Max. operating temperature 200°C; Max. operating pressure 60kg/cm².

  • Side-Mounting, Top-Mounting, Bottom-Mounting.

  • Mounting screw type have M8 ~ M16, 1/8″~1/2″PF / PT / BSP and etc.

  • The materials of lead wire and cable are PVC, XLPE and PTFE. ses the electrical circ

  • Mini Float Level Switch has obtained UL approved.

  • OEM / ODM and special specification are acceptable.

  • Since technologies of the product have more and more advance, the products need comply with a requirement for more safe, convenient and low cost. The float switches are extremely compact, simple and are easy to install on any small space.

These switches are not effected by electrical interference. They can withstand to chemicals, high temperatures and pressures if the correct material of float switch is selected by the customers. 2.Magnetic Float Level Switch-FC/FD Series

Principle

The single unit or multiple reed switch units arehoused tightly in stainless steel or engineeringplastic stem, and the permanent magnet issealed into the middle of the specified float ball(s). You can mount the float ball to penetrating through the stem, 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. The figures below show the float orientations on N.O. (Normal Open) and N.C. (Normal Close). 23aryp[

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 are simplified in same junction box (housing) to economize the external wiring construction.

  • FC(D) type magnetic float level switches are more economical in budget than other level switches by comparison in multiple points.

  • 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 andhigh temperature performances.
