P4.30-2 Meteo Dataloggers & Sensors: sensors 21.11.01 Datalogger DL2e, standard hardware system Datalogger with a memory for 32.000 measurements (extendable to 128.000) housed in a weather resistant (IP65), synthetic housing. Sensors The various sensors, together with a datalogger, can be used to construct a customer specific measuring system. Precipitation 16.98.47 Aerodynamic synthetic rain  gauge The design of the synthetic rain gauge is such that the disturbing influence of air-currents is reduced to a minimum. Wind 16.98.31 Wind speed sensor The wind speed sensor has a measuring range of 0.25 - 75 m/sec and an accuracy of 1% +/- 0.1 m/sec. For every 1.25 m wind passage a signal is given to the datalogger. 16.98.34 Wind direction sensor Sensor for the registration of the wind direction of air-currents. The wind vane will respond to wind speeds as low as 0.6 m/sec. Air pressure 16.98.29 Air pressure sensor Air pressure sensor for connection on DL2e datalogger.   16.99.29 Air pressure sensor Air pressure sensor for connection on Datahog 2 datalogger.
