Product Highlights
The DMK458 Pressure Transmitter offers a wide range of applications with its nominal pressure ranging from 0…40 mbar up to 0…20 bar. It provides a 2-wire output signal of 4…20 mA, and other output signals can be requested. The product is distinguished by its impressive product characteristics, including the LR-certificate from Lloyd’s Register, DNV-approval from Det Norske Veritas, ABS-certificate from the American Bureau of Shipping, and CCS-certificate from the China Classification Society.
It exhibits high overpressure resistance and excellent long-term stability. Optional versions are available, such as the IS-version (Ex ia), which ensures intrinsic safety for gases. Additionally, the transmitter can be equipped with a diaphragm made of AI2O3 99.9% for added durability, and the pressure port is constructed with CuNiFe material, making it resistant to seawater.
Applications
The monitoring of pressure during loading and unloading processes is a key application for the DMK 458 Pressure Transmitter. In the maritime industry, ensuring the safe and efficient transfer of liquids or bulk materials is paramount. This transmitter provides continuous and accurate pressure readings, allowing operators to closely monitor the flow and pressure within pipelines and tanks during these critical operations. This helps prevent overfilling, detect potential blockages, and maintain optimal conditions for cargo handling, thereby enhancing safety and operational efficiency.
Another vital function of the DMK 458 is the monitoring of a ship’s position and draught. The draught, which is the depth of the ship below the waterline, is crucial for safe navigation and stability. By measuring the hydrostatic pressure at various points, the transmitter can accurately determine the ship’s draught. This information is essential for captains and crew to ensure the vessel can safely pass through shallow waters, enter ports, and maintain proper trim and stability, especially when carrying varying loads.
The DMK 458 is also utilized in anti-heeling systems. Heeling refers to the undesirable tilting of a ship, often caused by uneven loading or external forces. Anti-heeling systems work by rapidly transferring ballast water between tanks to counteract this tilt and maintain the vessel’s upright position. The pressure transmitter plays a critical role by providing real-time data on the water levels and pressures within these ballast tanks, enabling the system to make precise adjustments and ensure the ship’s stability and safety.
For level measurement in ballast and storage tanks, the DMK 458 Pressure Transmitter offers reliable and accurate data. Ballast tanks are crucial for a ship’s stability, and storage tanks hold essential fluids like fuel, fresh water, or other cargo. The transmitter measures the hydrostatic pressure exerted by the liquid column, which directly correlates to the liquid level. This precise level information is indispensable for effective tank management, ensuring proper weight distribution, preventing overflows, and optimizing the use of onboard resources.
