Product advantages
The user-friendly all-in-one solution
The u[sonic]WS7 Modbus is the most compact and versatile sensor in the LAMBRECHT meteo weather sensor series. It measures wind direction and speed using ultrasonic measurements. It also provides data on global radiation, air temperature, humidity, and air pressure; the dew point is also calculated. The temperature and humidity sensor's vane shelter protects against unwanted weather influences, ensuring even more accurate measurements. The sensor's Modbus connection allows for easy integration into existing systems and facilitates communication with other devices.
- Measurement standard for global radiation: Spectrally flat Class C (ISO 9060:2018), moderate quality (WMO No. 8)
- Smart heating that depends on wind speed and direction
- Lamella protective shelter for precise measurements of the temperature and humidity sensor
- No moving measuring elements, therefore no wear
- Easy installation and high serviceability
