General Description
The 05103AP-10 Wind Monitor for Alpine Applications measures horizontal wind speed and direction. It is rugged and corrosion resistant, yet accurate and light weight. External housing surfaces are coated with a special ice resistant coating to improve performance in harsh alpine conditions. Both the propeller and vertical shafts use stainless steel precision grade ball bearings. The 05103AP-10 connects directly to Campbell Scientific dataloggers (CR1000, CR10X, and CR23X).Wind Speed
Propeller rotation produces an AC sine wave signal with frequency proportional to wind speed. This AC signal is induced in a stationary coil by a six pole magnet mounted on the propeller shaft. Three complete sine wave cycles are produced for each propeller revolution.
Wind Direction
Vane position is transmitted by a 10K ohm precision conductive plastic potentiometer which requires a regulated excitation voltage. With a constant voltage applied to the potentiometer, the output signal is an analog voltage directly proportional to wind direction angle.
Construction and Mounting
The instrument mounts on standard one inch pipe, outside diameter 34 mm (1.34 in). Campbell Scientific supplies a 10-inch pipe for mounting the Wind Monitor to the 019WM Crossarm. An orientation ring is provided so the instrument can be removed for maintenance and reinstalled without loss of wind direction reference. Both the mounting post assembly and the orientation ring are secured to the mounting pipe by stainless steel band clamps. Electrical connections are made in a junction box at the base. A variety of devices are available for signal conditioning, display, and recording of wind speed and direction.
