The Sperry Marine 2863-AB Speed Log Preamplifier Rev-AA is a critical component of the Sperry Marine NAVIKNOT Speed Log System, designed to process low-level signals generated by the vessel's speed log transducer. Installed between the transducer and the electronics unit, the preamplifier amplifies, conditions, and converts sensor signals into stable digital data for accurate vessel speed measurement.
Designed for continuous marine operation, the 2863-AB improves signal quality and minimizes electrical interference, ensuring reliable speed information is transmitted to the navigation system. The processed speed data is then distributed to bridge equipment including:
- Radar Systems
- ECDIS
- AIS
- Autopilot
- Voyage Data Recorder (VDR)
- Integrated Bridge Systems (IBS)
- Speed Repeaters
- Navigation Computers
The 2863-AB Rev-AA is commonly installed on commercial vessels equipped with Sperry Marine NAVIKNOT electromagnetic speed log systems, where dependable speed information is essential for safe navigation, collision avoidance, voyage planning, and maneuvering. The preamplifier is compatible with several NAVIKNOT speed log configurations and works alongside Sperry electromagnetic speed log sensors and electronics units.
At WAVETECH MARITIME, we supply used, reconditioned, and fully tested Sperry Marine 2863-AB Speed Log Preamplifiers sourced from commercial vessels. Every unit undergoes detailed inspection and functional testing before shipment. Worldwide shipping and technical support are available for shipowners, ship managers, shipyards, and marine service companies.
Whether replacing a failed module or maintaining your NAVIKNOT speed log system, the Sperry Marine 2863-AB Rev-AA Speed Log Preamplifier provides reliable signal processing and long-term operational performance.
