RADAR PRECIPITATION SENSOR - LUFFT WS100

Lufft WS100 is a sensor with radar technology and adjustable heating.
Using a 24-GHz Doppler radar, it measures the speed of all forms of condensed water. These include rain, freezing rain, hail, snow and sleet.
The low-energy sensor detects precipitation from the first drop.

Technical data

Measurement surface: 9 cm²
Precipitation types: Rain, snow, sleet, freezing rain, hail, drizzle; No precipitation (SYNOP 4677)
Principle: Doppler radar
Accuracy: ±0.16mm or ±10% of the measured value for liquid precipitation*
Resolution liquid precipitation: 0.01 / 0 .1 / 0.2 / 0.5 / 1.0 mm (pulse interface)

Measurement ranges
Droplet size: 0.3...5.0 mm
Drop Size Distribution: 11 drop size classes with bandwidth of 0.5 mm
Precipitation intensity: 0.01...200 mm/h / 0...7.874 inch/h
Particle velocity: 0.9...15.5 m/s
Solid precipitation: 5.1...~30 mm

*) Under laboratory conditions by means of Lufft test system: Reference drop simulator with 2.8 mm drop diameter and adjustable intensity between 10 and 200 mm/h.
