ROW: Oil Spill Detector - ATEX EXD

ROW: Oil Spill Detector - ATEX EXD

LDI's Remote Optical Watcher (ROW) ATEX EXD is an autonomous, non-contact sensor designed to detect oil on water surfaces in hazardous environments. With a 316 stainless steel flameproof enclosure, it is ATEX/IECEx certified for installation in Zone 1 areas.

The ROW ATEX EXD is an advanced sensor developed by Laser Diagnostic Instruments (LDI) to continuously monitor water surfaces and quickly detect the presence of oil in hazardous environments where flammable concentrations of flammable gases, vapours or mists are frequently present. Using UV fluorescence technology, the ROW can identify oil films as thin as 1 micron, enabling early detection and minimising the risk of false alarms. The sensor is designed for 24/7 operation in varied and demanding environmental conditions, from Arctic cold to extreme heat. With a robust IP68-certified hermetic design and an LED lifetime of up to five years, ROW requires minimal maintenance. Its low power consumption of less than 2 W enables off-grid installations with solar panels, batteries and wireless telemetry. The ROW is available in various enclosures, including aluminium, stainless steel and ATEX EXD, to suit different installation needs.

Features & benefits

  • High sensitivity: Capable of detecting oil films as thin as 1 micrometre, enabling early detection of oil spills.
  • 24/7 operation: Designed for continuous monitoring in all light and weather conditions.
  • Robust construction: IP68 certified hermetic design to withstand harsh environments and minimise maintenance needs.
  • Low power consumption: Consumes less than 2 W, allowing off-grid installations with alternative energy sources.
  • Flexible installation: Available in different housings (aluminium, stainless steel, ATEX EXD) to suit specific installation requirements.
  • Compatibility: Can be integrated with existing telemetry systems via RS-485 (Modbus), 4-20 mA and relay outputs.

Applications

  • Industrial plants: Monitoring water discharges to prevent environmental pollution and protect equipment.
  • Water treatment plants: Detection of oil pollution to ensure effective clean-up and protect water quality.
  • Harbour surveillance: Identification of oil spills from ships to maintain marine environmental standards.
  • Offshore installations: Continuous monitoring of water surfaces around oil platforms to quickly detect and respond to spills.
  • Environmental monitoring: Protecting sensitive ecosystems through early detection of oil pollution in lakes, rivers and seas.
