Magnetic Float Switch
is specially suitable for high and low level signalization or automatic level control (by starting & stopping pumps or opening & closing of valves) in vessels. Horizontal mounting type directly on vessel or on External Chamber.
Compact & rugged construction consisting of a free moving pivoted float assembly and a switch enclosure in non - magnetic material
to achieve undisturbed magnetic flux. It employs dual magnets, one carried by the float arm and other by the contact carriers housed in the switch enclosure. A change in liquid level brings the like poles of dual magnets opposite to each other and resulting repulsion force ensures a changeover of contacts with snap action. The magnetic transmission is glandless, leaving no scope for leakages from vessel into switch housing. These switches are manufactured in various materials, enclosures & special features to suit broad range of media / applications. They are designed to provide high repeatability and to minimizes effects of shock, vibration & Pressure.
Mounted internally or externally through a chamber. External mounting is resorted to, where space is a limiting factor or mechanical devices like stirrers operate within the tank. Besides, in applications like boilers, reaction kettles etc., with external mounting, isolating is possible for regular servicing. The switch is normally side-mounted, however for applications like slurry, top installation is preferred. The switch can be wired directly "to make or break electrical circuits", of burners, heaters, motor pumps, alarms and other such electrically operated devices.
