The PCE-A420 is a cup anemometer for measuring wind speed. The three horizontally aligned spherical cups, which are fixed crosswise or in a star shape on the vertical axis of the cup anemometer, record the wind speed during a measurement. The measuring principle is simple: the stronger the wind blows, the faster the half-open plastic cups turn. The speed of the cross rotation determines the wind speed.
This PCE wind flow meter, also referred to as the cup anemometer, offers a significant advantage in comparison to the standard impeller anemometers. The wind direction is not of crucial importance in the measurement of the flow rate. In order to be able to measure the wind speed accurately, the cup anemometer, in contrast to the impeller anemometer, does not have to be kept exactly in the wind direction. The orientation of the half-cups in different directions ensures that the cup star is set in motion independent of the direction. Thus, the smooth and light cup-cross reacts to even the smallest flow velocities. With a resolution of 0.1 m / s or 0.1 km / h, the measuring range of the cup anemometer is from 0.9 m / s up to 35 m / s or from 2.5 km / h up to 126.0 km / h. There are different units for the flow velocities with m / s, km / h, knots, miles / h, ft / min available.
The cup anemometer records the number of rotations per minute and thus the wind speed very accurately. The wind speed can be conveniently read-out via the LC display (28 x 19 mm) of the cup anemometer. The anemometer of PCE Instruments stores maximum and minimum values, which can be conveniently read again on the display later. To ensure that the last measurement results displayed can be viewed again, the cup anemometer also has a practical Data-Hold function. The measurement data are recorded and stored via a useful 100-point data logger. The cup anemometer is marked IP 65, meets all the conditions and is thus protected against the penetration of dust and moisture. To save the battery of the cup anemometer when not in use, the meter is equipped with an Auto-Power-Off function. After a short while, the cup anemometer turns off by itself.
