Modbus wind direction sensor WV4403/5H25

RS4854-20 mAModbus RTU

Wind direction sensor designed for different industries and sectors. WV4403 detects the vane position by using magnetic sensors avoiding wear and tear. It generates a 4-20mA analogue output or RS485 MODBUS signal, depending on version. The heated version generates 4-20mA output and works from -20 ºC. When the temperature is higher than +6º C, the heater switches itself off automatically to reduce the consumption. High resistance to radio frequency interference (RFI) and electromagnetic interference (EMI) RS485 MODBUS signal or 4-20mA passive analogue output Magnetic measuring principle, with no wear and tear or dead zones Stainless steel bearings WV4403/5H25 has been designed to be used in industrial applications. Connected to devices such as dataloggers, PLCs, analogue signal displays (see our references WM44-EVO11, V10, V12, BS100/3 4-20mA), it measures the wind direction and/or activates predefined alarm values. Application examples: Irrigation control system, automation in greenhouses, solar trackers, ropeways at ski resorts, cranes, wind turbines, weather stations etc. All those applications that contribute to a greater control and greater security. Besides, WV5H25 has been designed for those applications that involve working with sub-zero temperatures. OPERATING Survival speed: 200 km/h of wind speed It gives a RS485 MODBUS signal or 4-20 mA analogue output which depends on the wind speed. (see graphic) The vane must be orientated north as shown in the orientation section. RS485 version gives the wind direction in degrees. It calculates the average position in the last second. In static position it has 20 positions of 18º each one.
