CWS has integrated a dual barometric pressure sensor option for the Weather MicroServer. Developed in collaboration with one of our international representatives for a small airport application, this installation will be a Capricorn FLX Weather Station. The Weather MicroServer can be used with any of our weather station models. (While CWS weather stations are not FAA certified, they are used by many small airports in the US and around the world that are not subject to FAA certification.)
The dual barometer measurements are used to report the two (redundant) pressure readings, the difference between them, and calculated QNH and QFE based on average value of the two sensors.
The dual barometer sensor unit includes a weather shield outdoor installation kit. Depending on accuracy requirements, Class A or Class B barometers can be specified.http://www.columbiaweather.com/products/weather-monitoring/microserver/
