Product Description

This seawater level transmitter probe has a slim 22 mm outer diameter so that it can be easily installed in 1 inch diameter pipes.

The body is made from titanium alloy providing excellent corrosion resistance to salt water for long periods of time. The diaphragm is made from a ceramic alumina which is also highly corrosion resistant to saltwater conditions

The LMK487 ship draught and ballast tank level sensor has been approved by DNV-GL and Lloyd’s Register for use on a marine vessel, and ATEX / IECEx intrinsically safe approved for use in hazardous areas.

The 4-20mA current loop output can be custom scaled in the factory to any pressure, depth or level, and calibrated for a particular sea water specific gravity (SG).

Applications

Graving dock tidal inlet valve pit

Monitor the level of tidal seawater from a inlet valve pit which is used to fill a graving dock.
