PRINCIPLE
The Side Mounted Magnetic Level Switch has a 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 carries 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 and special features to suit broad range of media and applications. They are designed to provide high repeatability and to minimise effects of shock, vibration and pressure.
