Lufft WS510 Multi-Parameter Weather Sensor
The Lufft WS510 Multi-Parameter Weather Sensor integrates the Kipp & Zonen CMP10 pyranometer along with sensors for air temperature, humidity, pressure & wind.
- Integrated Kipp & Zonen CMP10 pyranometer for solar radiation measurements
- 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.
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.
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.
The pyranometer is based on the Kipp & Zonen CMP10 that uses the ISO 9060 Secondary Standard for measurements in the spectral range from 285 to 2800nm. The output is expressed in Watts per square meter.
