Description

SWS-200 Weather Sensor

Monitors extended present weather to identify visibility and precipitation, easily integrated into meteorological networks and data controllers


Feature

  • Selectable measurement range
  • Precipitation type, intensity and accumulation outputs
  • Instantaneous and averaged visibility outputs
  • Date and time stamp on data strings
  • 2 adjustable relays and 1 fault relay
  • Analogue outputs of visibility range
  • Extended self test and maintenance information

Spesification

Visibility and precipitation measurements
  • measurement range
*selectable: 2 km, 10 km, 20 km, 32 km or 50 km
  • measures
visibility (MOR – Meteorological Optical Range) reductions caused by : fog, haze, smoke, sand, drizzle, rain, snow and general precipitation
  • measurement accuracy
<=10% maximum
  • measurement principle
forward scatter meter with 45o angle
  • precipitation detection
rain: 0.015 mm/hr (0.0006 in/hr)
  • resolution:
snow: 0.0015 mm/hr (0.00006 in/hr)
  • maximum rain rate
250 mm/hr (10 in/hr)
  • rain rate accuracy
<=15%
  • intensities
light (-). moderate, heavy (+)
Outputs and reports
