The LMK458 submersible level sensor with nose cone protection is designed for measuring seawater level in floating dry dock ballast tanks. It has a range of 0 to 14 feet and is IP68 rated for long-term submersion. The sensor provides a 4 to 20mA output signal for easy integration with monitoring and control systems.
The LMK458 submersible level sensor with nose cone is designed for measuring the seawater level in floating dry dock ballast tanks. The sensor has a measurement range of 0 to 14 feet, making it suitable for most ballast tank depths. The sensor’s nose cone protects the diaphragm from damage during installation and use. The sensor is installed by lowering it into the ballast tank until the nose cone reaches the required measurement point. The measured seawater level is sent using a 4 to 20 milliamp current output signal through the submersible IP68 sealed cable to the floating dock monitoring and control system.
The LMK458 is a highly reliable and accurate sensor that is ideal for use in floating dry dock ballast tanks. The sensor is made of seawater-compatible materials and is IP68 rated for long-term submersion in seawater. The sensor’s 4 to 20 milliamp current output signal is compatible with most monitoring and control systems.
Floating dry docks are used to raise sea vessels out of the water so that maintenance can be carried out on the hull of the vessel. The structure contains many buoyancy chambers which are emptied and flooded to sink and raise a docking platform above and below the waterline. The level of seawater in each ballast compartment provides an exact measurement of the amount of buoyancy, so that the whole structure can be trimmed to maintain stability. Ships and boats enter the floating dry dock when the docking platform is below the surface and then seawater is pumped out of the ballast tanks to increase buoyancy gradually, and raise the platform and vessel slowly out of the water.
The LMK458 submersible level sensor is an essential part of the floating dry dock ballast tank system. The sensor provides accurate and reliable level measurement, which is essential for maintaining the stability of the floating dry dock.
