The Marinelite EML9000 Electromagnetic Speed Log is a professional marine navigation instrument designed to accurately measure a vessel’s Speed Through Water (STW) and calculate the total distance traveled. Utilizing advanced electromagnetic sensing technology based on Faraday’s Law of Electromagnetic Induction, the EML9000 delivers fast, stable, and highly accurate speed measurements without relying on moving mechanical parts. This design ensures reliable operation with minimal maintenance and excellent performance in a wide range of sea conditions.
The system features a 7-inch color touchscreen display that provides real-time speed, trip distance, total mileage, and system status information in a clear, user-friendly interface. It incorporates built-in diagnostic functions and alarms for sensor faults, power failure, overspeed, and system abnormalities, enhancing navigational safety and operational reliability. The EML9000 supports NMEA 0183 communication, enabling seamless integration with ECDIS, Radar, AIS, Autopilot, Voyage Data Recorder (VDR), GPS, and Integrated Bridge Systems (IBS).
Designed for commercial cargo ships, tankers, offshore support vessels, ferries, fishing vessels, and research ships, the Marinelite EML9000 offers rugged marine-grade construction with waterproof and corrosion-resistant components for continuous operation in harsh marine environments. Its high measurement accuracy, simple installation, and dependable performance make it an ideal solution for modern ship navigation and voyage monitoring.
