The LMK 457 marine level transmitter has a capacitive ceramic sensing diaphragm which is compatible with sea water and salt spray when the copper nickel alloy option is specified.

The LMK457 marine level transmitter is Germanischer Lloyd (GL) and Det Norske Veritas (DNV)approved for marine use and can be used on seawater ballast, fuel, oil, service and waste water systems.

ATEX approved for intrinsically safe use in hazardous environments the LMK-457 marine approved level transmitter can also be used on ship systems which are handling flammable and volatile chemicals such as oil, gas, liquid petroleum gas (LPG) and liquid natural gas (LNG).

The LMK-457 ballast level sensor comes in a range of pressure fittings for either lowering into a tank, screwing into a pipe or flange mounting to the wall of a tank.
