Product Highlights
The DMK456 Pressure Transmitter offers a wide range of nominal pressure options, starting from 0 … 40 mbar up to 0 … 20 bar. Its output signals are available in a 2-wire format, ranging from 4 … 20 mA, with other output signal options available upon request. The product boasts several notable characteristics, including an LR certificate from Lloyd’s Register, DNV approval from Det Norske Veritas, ABS certification from the American Bureau of Shipping, and CCS certification from the China Classification Society.
The pressure transmitter features a durable stainless steel field housing and is available in an IS version (temperature class T6) that is intrinsically safe for gases. It also offers high overpressure resistance, ensuring reliability in demanding environments. Optional versions of the DMK456 include a diaphragm made of AI2O3 99.9% and various inch threads and flush versions, providing flexibility for different application requirements.
Applications
The monitoring of the pressure during loading and unloading processes is a critical application for the DMK 456 Pressure Transmitter, especially in marine and industrial environments. During the transfer of liquids or gases, maintaining the correct pressure is essential to ensure safety, prevent overfilling, and avoid spillage. The DMK 456 provides accurate, real-time pressure readings, allowing operators to control the flow and detect any anomalies that could indicate leaks or blockages. This helps to optimize the efficiency of loading and unloading operations while minimizing risks to personnel and the environment.
Another important use is the monitoring of a ship’s position and draught. The draught of a vessel—the vertical distance between the waterline and the bottom of the hull—changes as cargo is loaded or unloaded. By measuring the pressure at specific points, the DMK 456 can help determine the ship’s draught and, consequently, its position in the water. This information is vital for ensuring the vessel’s stability, safety, and compliance with maritime regulations, as well as for optimizing cargo distribution.
The DMK 456 is also well-suited for use in anti-heeling systems. Heeling refers to the tilting of a ship to one side, which can occur due to uneven loading or external forces such as wind and waves. Anti-heeling systems use pressure transmitters like the DMK 456 to monitor the distribution of ballast water or other fluids within the ship. By providing precise pressure data, the transmitter enables the system to automatically adjust fluid levels and maintain the vessel’s balance, enhancing safety and operational efficiency.
For level measurement in ballast and storage tanks, the DMK 456 offers reliable performance even in harsh marine environments. Accurate level measurement is essential for managing ballast water, which is used to stabilize ships, as well as for monitoring the contents of storage tanks. The transmitter’s robust design and high resistance to corrosion make it ideal for continuous level monitoring, helping operators to prevent overfilling, detect leaks, and ensure optimal tank management.
Finally, the DMK 456 is used for monitoring of the internal pressure in liquid gas cargo tanks. Transporting liquefied gases requires strict control of internal tank pressure to prevent dangerous situations such as over-pressurization or leaks. The DMK 456 provides precise pressure readings, enabling operators to maintain safe conditions within the tanks and comply with safety regulations. Its stainless steel construction and field housing ensure durability and reliability, even in demanding marine and industrial settings.
