WS100 Radar Precipitation Sensor / Smart Disdrometer
Absolutely maintenance-free and extremely fast measurement of precipitation type (Rain, snow, sleet, freezing rain, hail) and intensity, thanks to radar measurement technology. The smart radar rain sensor & present weather detector!
Parameters measured: Rain/precipitation quantity, rain/precipitation type (Rain, snow, sleet, freezing rain, hail)
Measurement technology 24GHz Doppler radar
Product highlights Very fast response time, maintenance-free measurement, present weather detection
Interfaces RS-485 semi-duplex two-wire, SDI-12, pulse interface / UMB protocol, Modbus
Model: 8367.U04 T
The Lufft WS100 is our rain 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.
