Wind speed and direction sensor VMT 107A
Wind transmitter VMT107A is a combined sensor for wind speed and wind direction.
- Small dimensions
- Low-threshold starting speed
- Resistant to all weather conditions
- Anodized aluminum and plastic
- Different output signal
- Type calibrated in wind tunnel
- Minimal maintenance
- Suitable for national met office
For wind speed part of the sensor a lightweight three-cup assembly (Robinson's cup) is used which, with a stroboscope disc and optoelectronic elements, gives frequency output proportional to the wind speed.
