The ultrasonic wind sensor is seawater-resistant and designed without mechanical parts as they have been used with traditional \u201ccups and vanes\u201d.\u00a0 The sensor is heated to remove frost and ice formation from the sensor.<\/p>\n<p>The digital or analog output delivers instantaneous, average, min or max value with flexible measuring rate. We recommend using the Modbus RTU protocol for applications with Ammonit Meteo-40 data loggers.<\/p>\n<h3>Wind speed and direction<\/h3>\n<p>The wind measurement element uses 4 ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.<\/p>\n<h3>Virtual temperature<\/h3>\n<p>Due to the physical relationship between the velocity of propagation of sound and the air temperature, the approximate ambient temperature can be determined with the aid of ultrasound sensors.<\/p>\n<h3>Air pressure<\/h3>\n<p>The air pressure is measured by an integrated air pressure sensor.<\/p>\n<p>&nbsp;<\/p>\n<table border=\"1\" width=\"662\" cellspacing=\"1\" cellpadding=\"1\">\n<thead>\n<tr>\n<th colspan=\"4\" scope=\"col\">Wind Speed<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Measuring range<\/td>\n<td colspan=\"3\">0 &#8230; 90 m\/s<\/td>\n<\/tr>\n<tr>\n<td>Accuracy<\/td>\n<td colspan=\"3\">\u00b1 0.3 m\/s or 3 % (0 &#8230; 35 m\/s) RMS, \u00b1 5 % (&gt;35 m\/s) RMS<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td colspan=\"3\">0.1 m\/s<\/td>\n<\/tr>\n<tr>\n<th colspan=\"4\">Wind Direction<\/th>\n<\/tr>\n<tr>\n<td>Measuring range<\/td>\n<td colspan=\"3\">0 &#8230; 359.9 \u00b0<\/td>\n<\/tr>\n<tr>\n<td>Accuracy<\/td>\n<td colspan=\"3\">&lt; 3 \u00b0 RMSE &gt; 1.0 m\/s<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td colspan=\"3\">0.1\u00b0<\/td>\n<\/tr>\n<tr>\n<th colspan=\"4\">Air Pressure<\/th>\n<\/tr>\n<tr>\n<td>Principle<\/td>\n<td colspan=\"3\">MEMS capacitive<\/td>\n<\/tr>\n<tr>\n<td>Measuring range<\/td>\n<td colspan=\"3\">300 &#8230; 1200 hPa<\/td>\n<\/tr>\n<tr>\n<td>Accuracy<\/td>\n<td colspan=\"3\">\u00b1 1.5 hPa (0&#8230;40 \u00b0C)<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td colspan=\"3\">0.1 hPa<\/td>\n<\/tr>\n<tr>\n<th colspan=\"4\">Virtual Temperature<\/th>\n<\/tr>\n<tr>\n<td>Measuring range<\/td>\n<td colspan=\"3\">-50 &#8230; 70 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Accuracy<\/td>\n<td colspan=\"3\">\u00b1 2.0 K (without heater and without solar irradiation or wind speed &gt; 4 m\/s)<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td colspan=\"3\">0.1 \u00b0K<\/td>\n<\/tr>\n<tr>\n<th colspan=\"4\">Data Output Digital<\/th>\n<\/tr>\n<tr>\n<td>Interface<\/td>\n<td colspan=\"3\">RS485 Half-\/Full-duplex, isolated<\/td>\n<\/tr>\n<tr>\n<td>Baud rate<\/td>\n<td colspan=\"3\">1200 &#8230; 57600<\/td>\n<\/tr>\n<tr>\n<td>Meas. rate instant. value<\/td>\n<td colspan=\"3\">1 &#8230; 10 s<\/td>\n<\/tr>\n<tr>\n<td>Meas.
