The Walker 2090 Heated Ultrasonic Wind System is a high-precision, solid-state wind measurement solution manufactured by Lilley & Gillie (Walker Marine Instruments) in the United Kingdom. Designed specifically for commercial vessels, icebreakers, research ships, and offshore platforms operating in freezing or arctic environments, the Walker 2090 utilizes ultrasonic transducer technology paired with an integrated heating element to prevent ice build-up on the sensor head.

Eliminating moving mechanical parts such as cups and vanes, the system provides zero-maintenance, highly responsive measurements for wind speed and direction. The complete system consists of an aerodynamic, heated ultrasonic sensor head and a dedicated bridge indicator display that provides clear wind readouts and outputs standard digital NMEA 0183 data directly to ECDIS, RADAR, VDR, and integrated bridge systems.

Key Features:
• Solid-State Ultrasonic Sensing: Contains no mechanical moving parts, preventing wear, mechanical drag, and calibration drift.
• Thermostatically Controlled Sensor Heating: Heavy-duty internal heating element automatically prevents ice formation on transducers in sub-zero climates.
• Dual Wind Parameter Output: Accurately measures relative wind speed (knots, m/s, Beaufort scale) and wind direction across a 360-degree sector.
• High-Visibility Bridge Indicator: Crisp digital display with variable night-vision dimming control for easy reading on the bridge.
• Comprehensive NMEA 0183 Data Output: Generates standard IEC 61162-1 wind sentences ($WIMWV, $WIMWD) for vessel bridge networks.
• Extreme Weather Durability: Rugged, marine-grade sensor casing designed to withstand heavy salt spray, vibration, and polar sea conditions.
