Lovato LVFS Black Water Float Switch


Lovato LVFS Black Water Float Switch

The Lovato LVFS Black Water Float Switch is used for the civil and industrial control of levels of black water, e.g. sewage or waste water from industry. The regulator comprises a one-piece external blow-moulded polypropylene casing, with a fixed internal counterweight located in the cable exit area. The regulator contact is positioned centrally in its own watertight chamber. This insulated from the external casing by injecting closed-cell foam. This solution further increases protection against moisture leakage and heat insulates the watertight chamber housing the contact, eliminating the formation of condensation.
