The Walker 7070 Mk 2 Electromagnetic Speed Log is a type-approved solution, designed for precise speed measurements on larger vessels. Ideal for ships exceeding 500 GRT or 50 meters in length, this advanced system records both forward and reverse speeds, with a full-scale range from -20 to +80 knots. Its rugged design and reliable performance make it a go-to choice for commercial vessels navigating diverse conditions.
The Walker 7070 system features the robust P303 electronic unit, housed in a stainless-steel enclosure suited for placement near the hull. This durable setup ensures accurate data capture from the log sensor, even in the challenging environment at the vessel’s base. The control unit transmits NMEA0183 or 200PPNM signals to other onboard equipment, allowing seamless integration with navigation systems on the bridge. A shorter cable run to the sensor further enhances installation flexibility.
The P1248 Log Data Display is built to meet stringent maritime standards, including EN 60945:2002 for environmental and EMC requirements. The OLED display delivers crisp readings at any time of day, while a dimmer and optional remote dimming (P1275) make it adaptable to varied lighting conditions. Alarms and easy troubleshooting LEDs on the display add to its user-friendly design.
The system also supports retractable log sensors (P99), making maintenance simpler without requiring drydock access. With options for hull materials like steel, aluminum, and GRP/wood, and the ability to expand with multiple indicators via a daisy chain, the Walker 7070 Mk 2 delivers versatile and dependable speed tracking for maritime needs.
