Ultrasonic Wind Speed and Direction Sensor
No Moving Parts · Maintenance-Free Design · High-Precision Dual Measurement
The Dexonmarine Ultrasonic Wind Speed and Direction Sensor is a high-precision meteorological instrument designed for accurate and long-term wind measurement in marine and industrial environments.
Unlike traditional mechanical anemometers, it has no moving parts, ensuring zero maintenance, long service life, and high reliability even in harsh weather conditions. This sensor measures both wind speed and wind direction simultaneously using ultrasonic technology. It requires no on-site calibration and can be easily connected to a computer, data logger, or monitoring system via standard communication interfaces.
Core advantages
· Reliable for Long-Term Use — Ultrasonic technology with no mechanical wear ensures years of stable operation.
· Plug-and-Play Integration — Connects easily via RS232 or RS485 to data loggers, computers, or monitoring systems.
· Zero Maintenance — No calibration or mechanical upkeep required, reducing lifecycle costs.
· Accurate & Real-Time Data — Delivers precise wind speed and direction readings for navigation and safety monitoring.
· Durable Marine Construction — Lightweight, corrosion-resistant housing designed for harsh coastal conditions.
