Lufft WS400 Multi-Parameter Weather Sensor
The Lufft WS400 Multi-Parameter Weather Sensor simultaneously measures air temperature, humidity, pressure & precipitation in a compact platform with ventilated housing.
- 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 NexSens and other data loggers
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 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.
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.
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.
