One unit device for industrial application
Ultra sonic sensor for wind speed and direction with MODBUS RS485 or ANALOG 4-20 mA output
WUS4423 measures the wind movement by using ultrasonic transducers to detect speed and direction in one unit. Using this principle avoids wear and tear. It generates RS485 MODBUS signal or analog 4-20 mA.
WUS4423 has been designed to be used in industrial applications. It measures the wind speed and direction and normally is connected to PLCs or similar devices, examples:
- Irrigation control system
- automation in greenhouses
- solar trackers
- ropeways at ski resorts
- cranes
- wind turbines
- weather stations
- all those applications that contribute to a greater control and greater security.
Operation
Wind speed measurement up to 160 km/h
Survival speed: 200 km/h of wind speed.
It gives a RS485 MODBUS signal or analog 4-20 mA output. (see modbus section).
The WUS4423 must be oriented to north as shown in the mounting section to obtain a correct output.
The unit must be fixed on a vertical position
Heater
In heated WUS versions, the integrated heater significantly reduces the risk of malfunction caused by ice or snow accumulation on the transducers, ensuring reliable operation. The system is designed for energy efficiency, consuming power only when necessary.
- Automatic operation: Activates below +4ºC and deactivates above +6ºC.
- Same wiring: The connection remains identical to non-heated versions.
- Power consumption: Increases by 12W when active.
