Optical Weather Identifiers

The OWI-430 DSP-WIVIS™ is the most advanced present weather and visibility sensor ever made. The fully automated instrument provides accurate visibility, present weather and precipitation measurement in a single sensor. This 3rd generation intelligent sensor uses all digital signal processing (DSP)
for no-drift high-accuracy results. OSi’s patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 200 million field hours of real-world data from our sensors installed around the world. The result is the most advanced weather sensor in the world.

The DSP-WIVIS™ measures visibility and detects and quantifies rain, snow, drizzle, freezing and mixed precipitation conditions. The -DSH model identifies whether visibility impairments are caused by haze/fog vs. dust/smoke. The sensor is designed for year-round continuous operation in all climates from Antarctica to tropical rain forests. OSI’s advanced weather sensors provide critical weather information to airport, highway, military, research and meteorological weather information systems all over the world with over 3000 systems fielded. Sensing the environment is not a sideline business for us – it is our primary focus. When you need superior present weather information and high reliability, nothing else can match OSi’s DSP-WIVIS™.

Thanks to the new DSP electronics, the typical need for field calibration is completely eliminated. The single enclosure makes integration and installation simple. Adding the optional HIP-100 acoustic sensor provides for enhanced hail and ice pellet discrimination. The DSP-WIVIS™ is widely used by airports and regional DOT’s across the US and throughout the world. No other weather instrument can provide this powerful combination of high performance, low cost and proven reliability! No other company can provide the proven level of support and customer satisfaction that OSi does!

The OWI-650 LP-WIVIS™ has been designed from the ground up for quick deployment anywhere. The LP- WIVIS is the first present weather and visibility sensor designed for battery powered or solar powered applications.

The LP-WIVIS™ is more than just a sensor. It is a system. Other sensors including
wind, temperature, relative humidity, and barometric pressure may be easily added. The LP-WIVIS™ serves as both sensor and data acquisition system. No separate data acquisition system is required.

The fully automated instrument provides accurate visibility, present weather and precipitation measurement in a single sensor. This next generation intelligent sensor uses all digital signal processing (DSP) for no-drift high-accuracy results. OSi’s patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 25 year’s experience and over 200 million field hours of real-world data from our sensors installed around the world. The result is the most advanced/easily deployable weather sensor in the world.

The LP-WIVIS™ is already a low power present weather and visibility sensor but to further reduce the power requirements the LP-WIVIS™ may be operated in intermittent mode. In intermittent mode, the sensor is automatically powered up for one minute, reports present weather and visibility measurements and then is powered down. The heaters are independently controlled. In many environments the heaters are never powered on. Advanced detection algorithms report dew or frost on lens and control heater function.
