Sea water contains a significant level of salt which makes it highly corrosive to many materials. This makes seawater compatibility an essential consideration in the design of marine equipment used for ships, offshore platforms and other marine based structures.
Pastics, ceramics and special metal alloys have very good resistance to seawater corrosion and are often used in the design of smaller sensitive components, particular those which are very thin which and quickly affected by pitting and corrosion.
All voyage and safety critical equipment on a ship must be certified by the same approval body such as LR (Lloyd’s Register), GL (Germanischer Lloyd), DNV (Det Norske Veritas), ABS (American Bureau of Shipping) and CCS (China Classification Society) that audited and registered the whole ship, in order for it to be fitted and used on marine systems.
Pressure transmitters are measurement devices which combine an amplified 4 to 20 milliamp current loop output signal conditioning electronic module with a transducer for measuring the pressure of a liquid, vapour or gas.
