3 Overview

Magnetic induction wind meter is a measure of the instantaneous wind direction and speed instruments, mainly for field observation, by the anemometer and wind direction table composition. The key member includes a wind vane and wind cups. Vane by wind vane shaft is rotated around to drive the wind direction pointer on the compass direction. Wind cup Wind cup shaft is rotated around by wind, driven by the wind cup shaft lower end of the magnet is rotated to form a rotating magnetic field around the magnet The induction coil generates eddy currents in a changing magnetic field. Induction coil under the action of the electromagnetic force, the magnet rotates along the square To deflect. Induction coil deflected to a certain angle after reaching the torque balance and gossamer. Winds pointer The induction line Deflection angle in the circle indicates the wind speed wind speed dial.

4 legal management requirements

4.1 units of measurement Magnetic induction wind table should respectively "m/s" and "(°)" as wind speed and direction units. 4.2 The maximum permissible error Wind direction magnetic induction meter maximum permissible error of ± 22.5 °, wind speed maximum permissible error of ± (0.5m/s 0.05v). Note. v standard wind speed, m/s. 4.3 legal metrology marking and measuring instruments logo 4.3.1 legal metrology flags include the following. --- Measurement equipment manufacturing license logo and number (test prototype should stay out of the corresponding position); --- Induction wind flags and table type approval number (test prototype should stay out of the corresponding position; this entry is not mandatory provisions set); --- Product certification (with magnetic induction wind provided separately from the main unit). 4.3.2 measuring instruments identified include the following. --- Name induction wind table specification (model); ......
