The u[sonic]WS is the newest, most compact and system-capable addition to the Lambrecht meteo weather sensor series. Wind direction and speed are measured by ultrasound sensors, beyond the wind parameters the air temperature, humidity and pressure values are also determined; the dew point is calculated. The lamella shelter of the humidity and temperature sensor protects the sensor from the deteriorating effects of the climate and ensures improved and more accurate measurements.
- The WS7 measures 7 weather parameters: wind direction and speed, air temperature, rel. humidity, barometric pressure, global radiation, dew point
- Without moving measuring elements
- Intelligent heating depending on wind speed and wind direction
- Lamella shelter for accurate measurements of the temperature-humidity sensor
- Easy installation, easy to maintain
- With ModBus protocol

The perfect weather sensor for industrial use as well as under extreme environmental conditions. The WS7 measures wind direction and speed, air temperature, rel. humidity, barometric pressure, global radiation, and dew point with independent, integrated sensors for high accuracies of each individual parameter.
The WS7 does not have any moving parts meaning there is minimal need for maintenance and very easy to service.
Features:
- Extremely robust, compact weather sensor with highquality, pollutant-resistant housing made of anodized aluminium
- Ideal for use in extreme environmental conditions, e.g. deserts, tropics, high mountains
- Version with integrated heating system for year-round icing-free operation
- Lamella shelter for accurate measurements of the temperature-humidity sensors
- With ModBus protocol
- Power supply 6...60 VDC with integrated overvoltage protection
- Storage, evaluation and display of the measured values using the MeteoWare CS evaluation software
- Easy, space-saving mounting on 50 mm standard pipe
Applications:
- Land applications under any conditions
- Wind turbines
- Railway line monitoring
- Traffic meteorology
