Description
 

The Lufft WS600 Weather Sensor simultaneously measures air temperature, humidity, pressure, precipitation & wind with an integrated electronic compass for corrected wind direction on moving platforms.

Lufft WS600 Features

  • 24GHz Doppler radar measures precipitation drop speed and calculates quantity & type

  • Easily mounts to 2" diameter pipe with integrated bracket mount & U-bolts

  • SDI-12 output for integration with data loggers

Overview
The Lufft family of multi-parameter weather sensors offer a cost-effective, compact alternative for the acquisition of a variety of measurement parameters on land- and buoy-based weather stations. Depending on the model, each Lufft weather sensor will measure a different combination of weather parameters to meet a wide variety of applications.

Air Temperature & Humidity
Temperature is measured using a highly accurate NTC-resistor, while humidity is measured using a capacitive humidity sensor. Both sensors are located in a ventilated radiation shield to reduce the effects of solar radiation.

Pressure
Absolute air pressure is measured using a built-in MEMS sensor. The relative air pressure referenced to sea level is calculated using the barometric formula with the aid of the local altitude, which is user-configurable on the equipment.

Wind Speed & Direction
The wind sensor uses four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Compass
The integrated electronic compass can be used to check the north-south adjustment of the sensor housing for wind direction measurement. It is also used to calculate the compass-corrected wind direction.

Precipitation
Tried and tested radar technology is used to measure precipitation. The precipitation sensor works with a 24GHz Doppler radar, which measures the drop speed and calculates precipitation quantity and type by correlating drop size and speed.
