The Wind Speed sensor is built around an AC generator (without brushes) and a rectifier. It has a very low starting speed, while measuring up to 200 km/h. All external sensor parts are made of highly resistive plastics.

The Wind Direction sensor is based on a precision potentiometer.

Both sensors are absolutely maintenance free (periodical cleaning apart to free moving parts from e.g. cob webs) and maintain their original accuracy for many years. The statistical drop out rate of the sensor is less than 3 % within the first 8 years of operation.

This sensor is a top quality product Made in Switzerland. Permanent quality control based on an ISO-9000 equivalent Norm, executed by SCS, provides the product with the "Swiss-Calibration" quality mark. According to multilateral agreements this quality mark is approved and accepted in the following countries: A, CH, D, DK, F, GB, IE, I, N, NL, S, SF, RSA

The sensor comes complete with a mast mounting arm, 2 pipe clamps, 2m of cable and some cable ties.

Useful Accessories:
In a default setup a wind speed reading is taken once per minute and averaged over 15 minutes. This will give you accurate information about average wind speed, but it blanks out gusts. If you also need accurate information about the top wind speeds occurring within a given period, e.g. 15 minutes, you should look at the A508 WindMAX. Click here to read more!
