Lufft WS100 Radar Precipitation Sensor / Smart Disdrometer

WS100 Radar Precipitation Sensor / Smart Disdrometer

Maintenance-free and extremely fast measurement of rain, snow, sleet, freezing rain, hail and intensity, thanks to radar measurement technology. The smart radar rain sensor & present weather detector!

Using a 24-GHz Doppler radar and adjustable heating, the Lufft WS100 measures the speed of all forms of condensed water: rain, freezing rain, hail, snow and sleet.
The low-energy sensor detects precipitation from the first drop. Uses include: hydrology and water management, agricultural and environmental science, building automation, meteorology or airport and traffic control.

  • 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.

Product Advantages of the Lufft WS100 Radar Precipitation Sensor

Absolutely maintenance-free and low-energy 24-hour operation

  • Maintenance-free operation through ingenious technology without any moving parts
  • Energy-saving sensor thanks to the improved ECO mode (0.4 VA)
  • Extended heating capacity allows operation in summer as well as in winter
  • Improved heating power with lower power consumption: Sensor heating integrated directly on the dome wall, power consumption with 9 VA heating.
  • Very long service life and high operational reliability due to high quality components.

Every second counts: Precise precipitation measurement from the first drop

  • Extremely fast measurement from the first raindrop
  • Detection of precipitation and rainfall (rain, freezing rain, hail, snow and sleet)
  • Detection of drop size (0.3 to 5 mm)
  • Differentiation between 11 classifications of drop sizes
  • Sensor provides rain intensity with higher resolution starting from 0.01 mm
  • Improved measurement accuracy thanks to patented self-developed radar module

Precision sensor with radar technology designed for all industrial needs
