Inductive Maritime - DNV-Approved For Ships, Ports And Offshore!

For 20 years, sensors made by Contrinex have proved their reliability in ships, ports and offshore. The Maritime range of embeddable inductive sensors, certified by DNV, offers unrivalled performance features based on Full Inox technology. With a one-piece housing in V4A/AISI 316L stainless steel and an enclosure rating of IP68/IP69K, they are not only impervious, but also corrosion-proof and resistant to salt water. Their EMC protection also meets specific maritime requirements, particularly with regard to power supply variations and low frequency immunity. They offer the longest service life of any inductive sensor on the market, even in the harshest marine environments. The maximum operating pressure is 80 bar or 500 bar (peak 800 bar) for P12G high-pressure types. Depending on sensor size (M12, C23, M18 or M30), operating distances of 6, 7, 10 or 20 mm are available. In the PNP version, sensors also include an IO-Link interface for point-to-point communication with the controller of the system.

The range also includes DNV-approved M10 types with Classics technology.

DNV is an internationally accredited certification body that establishes and maintains technical standards for the construction and operation of ships and other offshore mobile structures in international waters. Its classification standards comprise safety, reliability and environmental requirements. DNV is authorized by 130 maritime administrations to perform certification or verification on their behalf.

DNV was created in 2013 with the merger of Det Norske Veritas (Norway) and Germanischer Lloyd (Germany).
