Weather sensor


  • professional meteorological application
  • wind turbines on- and off-shore
  • ship weather station
  • building automation and environmental engineering
  • traffic and industrial meteorology
  • wind warning and event engineering
  • photovoltaic large-scale plants
  • alpine applications

For 6 weather parameters

The u[sonic]WS is the newest, most compact and system-capable addition to the Lambrecht meteo weather sensor series. 
The sensor has no moving measuring elements and is therefore low-maintenance. The intelligent heating system works in relation to the wind speed and direction and keeps the sensor ice-free even under extreme weather conditions. 
The u[sonic]WS6 easily meets the special challenges of alpine and maritime applications.
A wide variety of interfaces and protocols are available. There are no limits for the u[sonic]WS6 when it comes to its applications.

  • without moving measuring elements
  • 6 weather parameters: wind direction and speed, air temperature, rel. humidity, barometric pressure, dew point
  • intelligent heating depending on wind speed and wind direction
  • lamella shelter for accurate mea­surements of the temperature-humidity sensor
  • easy installation, easy to maintain

METEO-LCD-IND · Digital indicatorMETEO-LCD-IND Digital indicator

This indicator is extremely versatile and flexible. The high contrast display can be adjusted by a dimmer to the prevailing lighting conditions. The compact design proves to be very advantageous and cost efficient when mounted into control panels. The instruments are reliable and cross-linkable. They can, when series connected, display all 6 measured main parameters at the same time.

  • Big, graphic, high-resolution display with background illumination
  • Contrast and brightness adjustable
  • Variety with waterproof front plate design
  • Low mounting depth
  • Galvanically separated supply and signal channels
  • Momentary, mean and extreme values
