Enhancing Maritime Safety with DNV-Approved Inductive Sensors

In the dynamic and challenging world of maritime operations, reliability and durability are paramount. For two decades, Contrinex has been at the forefront, delivering cutting-edge sensor technology that has stood the test of time in ships, ports, and offshore applications. Our Maritime range of embeddable inductive sensors, certified by DNV, promises unparalleled performance features, setting a new standard for maritime sensor solutions.

DNV-Approved Excellence:

Contrinex's Maritime range boasts DNV certification, ensuring approval for deployment in ships, ports, and offshore installations. This endorsement speaks volumes about the sensors' reliability and adherence to the rigorous standards set by DNV. The sensors are meticulously designed to meet the demanding requirements of the maritime industry, providing a level of performance that surpasses expectations.

Full Inox Technology:

At the heart of Contrinex's Maritime sensors is the Full Inox technology. This innovative approach features a one-piece housing crafted from V4A/AISI 316L stainless steel, rendering the sensors impervious to the harsh marine environment. The enclosure is rated IP68/IP69K, making them not only corrosion-proof but also resistant to saltwater. This robust construction ensures longevity and reliability, even in the most challenging maritime conditions.

EMC Protection for Maritime Excellence:

Contrinex understands the unique challenges posed by the maritime environment, especially concerning electromagnetic compatibility (EMC). The Maritime sensors are engineered with EMC protection that meets specific maritime requirements, including resistance to power supply variations and low-frequency immunity. This ensures consistent and reliable performance, contributing to the safety and efficiency of maritime operations.

Versatility and Performance:

Contrinex's Maritime range offers a range of sizes (M12, C23, M18, or M30) with varying operating distances (6, 7, 10, or 20 mm), catering to diverse applications. In the PNP version, sensors come equipped with an IO-Link interface, facilitating seamless point-to-point communication with the system controller. The P12G high-pressure types boast a maximum operating pressure of 80 bar or 500 bar (peak 800 bar), making them ideal for high-pressure maritime applications.

DNV-Approved M10 Types:

In addition to the extensive range, Contrinex offers DNV-approved M10 types featuring Classics technology. These sensors provide a reliable option for specific applications where the M10 size is preferred, ensuring that Contrinex has a solution for every maritime need.

Beyond DNV Certification:

While the DNV-approved Maritime range stands out for its excellence, Contrinex also recommends other sensor ranges for maritime use. The Extreme, Washdown, Analog Output, Basic C44 series are reliable options for various applications within maritime environments, offering flexibility and performance tailored to specific needs.


Contrinex's commitment to excellence and innovation shines through in the Maritime range of inductive sensors. With DNV certification, Full Inox technology, and a host of performance features, these sensors redefine reliability in maritime applications. As the maritime industry continues to evolve, Contrinex remains a trusted partner, ensuring safety, efficiency, and durability through its state-of-the-art sensor solutions.
