The user-friendly all-in-one solution

The u[sonic]WS7 Modbus is the most compact and versatile sensor in the LAMBRECHT meteo weather sensor series. It measures wind direction and speed using ultrasonic measurements. Additionally, it provides data on global radiation, air temperature, humidity, and air pressure; the dew point is also calculated. The lamella shelter of the temperature and humidity sensor protects against unwanted weather influences, ensuring even more accurate measurements. The Modbus connection of the sensor allows for easy integration into existing systems and facilitates communication with other devices.

  • 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
