Seawater-resistant pressure transmitters designed for shipboard and marine applications are essential components for monitoring and controlling various systems within vessels and offshore platforms. These specialized pressure transmitters are engineered to withstand the challenging conditions encountered at sea, including exposure to seawater, salt spray, humidity, and fluctuating temperatures.
Advantages
- Corrosion Resistance: The wetted materials used in these transmitters are carefully selected to resist corrosion caused by seawater and other harsh marine elements. This ensures long-term reliability and accuracy in pressure measurement. Common materials used for wetted parts include titanium, Hastelloy C-276, and Copper-Nickel alloys.
- Marine Certifications: These transmitters comply with stringent marine standards and regulations, such as those set by the International Maritime Organization (IMO) and classification societies like DNV GL, Lloyd’s Register, and ABS. These certifications ensure the transmitters meet the safety and performance requirements for use in the marine environment.
- 4-20mA Current Loop Output: The 4-20mA current loop output is a standard signal widely used in industrial automation and process control. This signal provides a reliable means of transmitting pressure readings over long distances, even in environments with electrical noise.
Applications
These pressure transmitters can be used to monitor various parameters on ships, including:
- Engine Cooling Systems: Maintain optimal engine performance by monitoring seawater pressure within the cooling system. This helps ensure efficient heat exchange and prevents overheating.
- Bilge Systems: Monitor pressure in bilge pumps and piping to ensure proper operation and prevent flooding. Detect blockages or leaks that could compromise the system.
- Ballast Pumps: Optimize ballast operations by monitoring seawater pressure during ballast intake and discharge. This helps ensure efficient pump performance and prevents damage.
- Desalination Systems: Control and monitor the pressure of seawater within desalination systems. This ensures optimal system performance and the production of fresh water.
- Seawater Intake Systems: Monitor the pressure of seawater intake lines to ensure a consistent supply of water for various onboard systems, including cooling, firefighting, and desalination.
- Seawater Ice Makers for Trawlers: Maintain efficient operation of seawater ice makers, crucial for preserving the catch on fishing trawlers. Monitor pressure in the system to ensure optimal ice production and prevent equipment malfunctions.
