Seven meteorological parameters in one device

The u[sonic]WS7 is the most compact and versatile sensor in the LAMBRECHT meteo weather sensor series. Wind direction and speed are determined through ultrasonic measurement. In addition, global radiation, air temperature, humidity, and air pressure are provided; the dew point is also calculated. The lamella shelter of the temperature and humidity sensor eliminates unwanted weather influences, ensuring even more accurate measurements. A wide variety of interfaces and protocols are available. The applications of the u[sonic]WS7 know no bounds.

  • Measurement standard for global radiation: Spectrally flat Class C (ISO 9060:2018), moderate quality (WMO-No. 8)
  • Intelligent heating that depends on wind speed and direction
  • Lamella shelter for precise measurements of the temperature and humidity sensor
  • No moving measuring elements, thus no wear and tear
  • Easy installation and high service friendliness
