Seven meteorological parameters in one device

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. A wide variety of interfaces and protocols are available. There are no limits for the u[sonic]WS7 when it comes to its applications.

  • No moving measuring elements, no wear
  • Seven weather parameters: wind direction and speed, air temperature, rel. humidity, barometric pressure, global radiation, dew point
  • Intelligent heating depending on wind speed and wind direction
  • Lamella shelter for accurate mea­surements of the temperature-humidity sensor
  • Easy to install, easy to maintain
