The maritime, all-in-one sensor for six weather parameters

u[sonic]WS6-NAV is a compact weather sensor with no moving parts. The wind parameters are measured with ultrasonic technology. Its robust, seawater-resistant aluminum housing ensures use under harsh conditions on ships and on wind turbines. The integrated heating keeps the weather sensor ice-free even in extreme conditions down to -50 °C. The sensor has an NMEA 0183 output according to marine standard.

Safety is a top priority on the high seas. The u[sonic]WS6-NAV has been tested by official institutions and is certified according to the EN 60945 standard for marine equipment. Minimum maintenance is needed for the sensor, routine calibrations are not required. The lamellar protective housing can be easily disassembled to clean or replace the sinter cap of the humidity-temperature sensor inside.

  • Six measurement parameters: Wind direction, wind speed, air temperature, air humidity, barometric pressure, dew point temperature (calculated value)
  • Simple installation with only one cable connection
  • Wear-free operation because no moving measuring elements
  • Easy to service due to removable lamella protection shelter
