RS485 wind direction sensor 3S-WD-MB

ModbusModbus RTUIP54

Product description
The 3S-WD-MB Wind Direction Sensor is a vane-driven Hall-effect instrument for continuous measurement of horizontal wind direction (°). It comprises a rotating vane and a sensor body and provides a digital Modbus RTU output over RS485 for direct integration with data loggers and control systems. Supplied with mounting hardware and a 3 m weather-resistant cable.

Applications

• Industrial meteorological stations and site monitoring
• Photovoltaic plant monitoring (module temperature/wind interaction)
• Wind assessment for structural and warranty documentation
• Agricultural and environmental monitoring systems
