The CS120A Atmospheric Visibility Sensor and PWS100 Present Weather Sensor give visibility information; the PWS100 and CS125 Present Weather and Visibility Sensor also provide present weather as METAR codes. These sensors comply with CAA and ICAO guidance, and meet or exceed all recommendations and specifications. (This includes CAP437, CAP670, and CAP746.)
Campbell Scientific data loggers are reliable and robust, and more than capable of all data collection and signal processing required. Calculations of QFE and QNH from pressure sensors, including comparisons between multiple sensors, are possible.
We offer a variety of products that can be used to create systems for Aviation Weather. Many of the major components used to create these systems are listed below. Please let us know if we can help you configure a system.
