Precipitation Sensors

Smart disdrometer

WS100 Radar Precipitation Sensor/Smart Disdrometer

The Lufft WS100 is our maintenance-free radar precipitation sensor. It recognizes the type and amount of precipitation from the first drop. The sensor is suitable for hard-to-reach places.

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

Rain gauge

Rain Gauge WTB100

Tipping bucket rain gauge with bounce-free reed contact.

Parameters Measured: Rain/precipitation quantity

Measurement Technology: Tipping bucket with bounce-free reed contact (normally closed)

Product Highlights: Resolution can be switched from 0.2 to 0.5 with reduction ring, connectable to any WS-sensor without precipitation measurement

Interfaces: Impulse output (reed contact)

Road precipitation sensor

Radar Precipitation Sensor R2S-UMB

The radar precipitation sensor Lufft R2S-UMB allows fast measurement of precipitation intensity and distinguishs between precipitation type (Rain, snow, sleet, freezing rain, hail). The operation is maintenance-free, thanks to radar measurement technology.

Parameters Measured: Rain/precipitation quantity, rain/precipitation type (Rain, snow, sleet, freezing rain, hail)
