Product advantages
Seven meteorological parameters in one device
The u[sonic]WS7 is the most versatile sensor in the LAMBRECHT series and provides precise weather data in a very small space. It measures wind direction and speed using ultrasound, as well as global radiation, temperature, humidity, and air pressure. The dew point is calculated automatically for comprehensive analysis. The slatted protective shelter reliably protects the humidity and temperature sensor from the effects of weather and ensures particularly accurate measurements. The intelligent, wind-dependent heating system guarantees reliable operation even in adverse conditions.
- Measurement standard for global radiation: Spectrally flat Class C (ISO 9060:2018), moderate quality (WMO No. 8)
- Smart heating: Automatic adjustment to wind direction and speed
- Lamella sensor shelter: For precise temperature and humidity measurements
- Robust and easy to integrate: Maintenance-free, no moving parts, with flexible interfaces
