Explosive Area Oil Detectors

Autonomous non-contact sensor for detection of oil in explosive environments. Highly accurate, easy to maintain, finds oil spills and leaks early so you can respond faster.


The ROW ATEX EXD oil detector is designed to be installed within hazardous areas where ignitable concentrations of flammable gases or vapours often exist. These industrial areas are classified as Zone 1 based on established international standards ATEX/IECEx

The ROW ATEX EXD oil detector is encased in a flameproof (explosion-proof) enclosure made from 316 stainless steel, making it ideal for the toughest environments. The whole system is certified ATEX/IECEx by DNV Presafe for Zone 1 installations.

With the ROW’s optical technology for non-contact monitoring, there is no marine biofouling or oil contaminating the sensor. This limits the need for regular cleaning.

The Science

To detect oil slicks as thin as a single micron from up to 10m above the water, the ROW pulses a UV beam at the surface and excites any oil molecules in the target area. Using oil’s native fluorescence, ROW is calibrated to identify the specific wavelength signal of oil and send out an alert.

After 20 years of developing remote-sensing systems, LDI has mastered the technology better than anyone else.

Industry leading Sensitivity – 1µm

Advanced software algorithms are calibrated to detect oil down to single-micron layers and minimize false alarms.
