OWI-432 DSP-WIVIS Present Weather and Visibility Sensor

Categories: Weather & Meteorological Instrumentation, Weather Sensors & Stations, Visibility and Snow Depth Sensors,

The OWI-432 Present Weather Sensor optically measures precipitation induced scintillation and extinction coefficient and applies algorithms to automatically determine the precipitation type, precipitation rate, and visibility.

OWI-432 delivers accurate measurement of precipitation in all weather conditions. Equipped with a dual measurement system, the WIVIS can use both the precipitation and visibility information for a more robust algorithm to optimize performance.

Designed for rugged, unattended operation, more than 1,000 WIVIS have been field proven in adverse environments in North America, Europe, the Far East, and even Antarctica. As of 2005, OSI has accumulated more than 100 million hours of field experience with optical precipitation and visibility sensors!

OWI -432 is equipped with added data processing capacity: 4 analog channels and a secondary serial communication port are available through the auxiliary connector.

You can add:

  • Meteorological temperature and humidity probes
  • Digital and analog wind sensors
  • Cloud height sensors (ceilometers)
  • Digital and analog barometric pressure sensors Other analog or digital sensors.

OWI-432 features

  • Reports over 50 NWS / WMO codes Supports add-on sensors
  • Unaffected by dust or buildup on lenses
  • No field calibration required
  • Virtually no maintenance required
  • Built-in self diagnostics & testing.
