OPTICAL SCIENTIFIC INC (OSI) OWV-300 Optical Wind & Visibility Sensor

Categories: Weather & Meteorological Instrumentation, Dust & Particulate Monitors, Flow & Velocity,
Brand:

Measures Turbulence/ wind movement and atmospheric visibility over long path lengths (50-200m).
Uses combination Long Path Optical Extinction and Optical Scintillation technology.

All the electronics are housed in the OWV with a folded path being established by placing a corner cube reflector down-range at the desired distance.

OWV can distinguish between different types of visibility – fog/haze vs dust/smoke.
Provides 1D/2D and 3D wind movement as well as turbulence strength.
Can be configured for wake vortex detection at airports – tested by NASA.
Long- Term reliability, low maintenance, rugged all weather design, easy installation.

Communications – choose between RS-232 or RS-485, directly or through network via Ethernet.
