NBR Side Mounted Level Switch

It is an economical, maintenance free and a very reliable device used for high, low or intermediate point level switching. It is ideal for tanks with inaccessible tops or bottoms and where insertion depths of top mounted models are exceeded. The construction is compact & rugged with a free moving pivoted float assembly. The Switch assembly is mounted in a non-magnetic material to achieve undisturbed magnetic flux. It employs dual magnets, one linked with the float arm and other by the contract carriers housed in the switch enclosure. Change in the liquid level brings the like poles of dual magnets opposite to each other & resulting repulsion force ensures a changeover of contacts with snap action. The magnetic transmission is gland less so there is no scope of leakage from vessel into switch housing. These switches are manufactured in various materials and enclosures to suit broad range of media/applications. They are designed to provide high repeatability and to minimize effects of shock, vibration & pressure.
