Page 6: Operating Principle
User manual and maintenance t031-di TVV-TVVR.docx 2.1 Operating principle The 3 cups at the top of the sensor rotate clockwise. When the wind blows the movement is transmitted by a steel shaft inside the sensor body, on the end of the shaft a 6-pole magnet is fixed, which rotates together with the shaft. -
Page 7: Installation And Maintenance
The TVV transducer is normally positioned (according to WMO standards) at a height of about 10 meters from the ground level. Normally, in Siap+Micros weather stations, it is installed with brackets equipped with 40mm diameter U-bolts (sensor stem diameter) fixed to the pole. -
