Horizontal Float Switch 'KF-200/KFG-200'

Horizontal Float Switch 'KF-200/KFG-200'

KF-200 series side-mounted float switch with a simple structure that reliably captures the liquid level - special specification!

Introducing the special specifications of the horizontal mounting float switch in the KF-200 series, which reliably captures the liquid level with a simple structure! - Float with Bellows: Model KF-209 The bellows prevent the intrusion of fine solid particles mixed in the measuring liquid into the float's moving parts, ensuring it continues to operate. - Rust-resistant Bellows Float Switch: Model KF-207BR To prevent rust caused by standard stainless steel materials in seawater, the float is made of PVC, and the liquid contact parts are coated with tar epoxy. - Horizontal Type Vertical Mounting: Model KF-207F When viscous liquids or liquids mixed with impurities and debris are mounted horizontally, there is a possibility of them entering the moving parts. This model is suitable for cases where vertical mounting from the top of the tank is desired. Additionally, we manufacture level switches suitable for various applications, including explosion-proof specifications, heat-resistant specifications, models with operation confirmation test levers, two-contact output specifications, and products that have obtained NK certification. If you have any concerns regarding liquid level measurement, please feel free to contact us.

Horizontal Float Switch 'KF-200/KFG-200'

Horizontal Float Switch 'KF-200/KFG-200'

Capable of handling difficult applications with a rich variety of options! Reliably captures liquid levels with a simple mechanism! Horizontal float switch KF-200 series.

The horizontal float switch is a sensor that detects liquid level by utilizing the buoyancy of a float. Its operating principle involves the ON-OFF switching of contact output through the mutual magnetic action between a magnet attached to the end of the float and a magnet inside a case separated by a partition. In addition to the standard KF-207 model, we also offer custom-made options tailored to the measuring liquid and conditions. - For stable measurement of high-viscosity liquids or liquids containing impurities, we have the KF-207F model, which is mounted vertically. - If the liquid contains fine solids, such as sewage or scum, which may prevent the float from moving, we offer the KF-209 model with a bellows. - For use in ships where chattering needs to be prevented, we provide the KF-207K model with a larger float size (φ40-200L). Additionally, we manufacture level switches suitable for various applications, including explosion-proof specifications, heat-resistant specifications, screw-mounted specifications, models with operational test levers, two-contact output specifications, and products certified by NK. If you have any concerns regarding liquid level measurement, please feel free to contact us.
