FAN ASPIRATED METEOROLOGICAL MEASUREMENT SYSTEM PROVIDING HIGH ACCURACY DATA FROM BAROMETRIC PRESSURE, TEMPERATURE, AND RELATIVE HUMIDITY SENSORS. THIS FULLY INTEGRATED SYSTEM IS HOUSED IN ENVIRONMENTAL ENCLOSURES ALLOWING INDOOR OR OUTDOOR MOUNTING. A SOLAR RADIATION SHIELD PROTECTS THE TEMPERATURE AND HUMIDITY SENSORS FROM PRECIPITATION AND SOLAR RADIATION. THE UNIT UTILIZES A HIGH PERFORMANCE PRESSURE PORT TO REDUCE DYNAMIC PRESSURE ERRORS CAUSED BY WIND. MICROPROCESSOR BASED ELECTRONICS PROVIDE FULLY TEMPERATURE COMPENSATED AND LINEARIZED OUTPUTS VIA A BI-DIRECTIONAL RS-232/485 INTERFACE. THE SERIAL INTERFACE ALLOWS COMPLETE REMOTE CONFIGURATION AND CONTROL OF ALL OPERATING PARAMETERS INCLUDING RESOLUTION, SAMPLE RATES, CHOICE OF ENGINEERING UNITS, INTEGRATION TIME AND SAMPLING COMMANDS. OTHER FEATURES INCLUDE INSTRUMENT STATUS LED INDICATORS. THE UNITS POWER REQUIREMENTS ARE 11 TO 14 VDC AND ITS WEIGHT IS 4.26 KG.
