The Walker 5002 Ultrasonic Wind and Weather System is a comprehensive, solid-state meteorological monitoring solution manufactured by Lilley & Gillie (Walker Marine Technology) in the United Kingdom. Designed for commercial shipping, research vessels, offshore platforms, and naval auxiliaries, the Walker 5002 integrates solid-state ultrasonic wind sensing with multi-parameter meteorological data distribution into a single bridge display console.

By eliminating mechanical cups and vanes, the system provides friction-free wind speed and direction measurement with zero mechanical wear or calibration drift. In addition to wind parameters, the system processes barometric pressure, ambient temperature, and relative humidity data. The compact bridge display features high-contrast digital readouts, variable night-vision dimming, and comprehensive NMEA 0183 serial outputs for ECDIS, RADAR, VDR, and Integrated Bridge Systems (IBS).

Key Features:
• Solid-State Ultrasonic Sensing: Contains no mechanical moving parts, delivering high accuracy and low maintenance in severe ocean environments.
• Comprehensive Weather Monitoring: Displays relative wind speed, wind direction, barometric pressure, temperature, and relative humidity.
• Clear Digital Bridge Indicator: High-visibility multi-information display with front-panel night backlighting dimmer.
• NMEA 0183 Serial Output: Transmits standard IEC 61162-1 data sentences directly to bridge navigation equipment and data loggers.
• Programmable Alarm Limits: User-configurable audible and visual alerts for high wind speed limits and gust thresholds.
• Heavy-Duty Construction: Masthead sensor array is housed in corrosion-resistant marine alloys designed for high vibration and extreme weather exposure.
