Wind transmitter VMT 107A is a combined digital optoelectronic sensor for wind speed and wind direction. It is made from naturally anodised aluminium and stainless steel. Quality sealed ball bearings are used for both speed and direction measuring systems.

For wind speed part of the sensor a lightweight three-cup assembly is used which, with a stroboscope disc and optoelectronic elements, gives frequency output proportional to the wind speed.

For wind direction part, a vane with the 6-bit optoelectronic Gray encoder is used. All electronic elements are protected against overvoltages by resistors and Zener diodes. Normal additional mechanical load (freezing) cannot damage the sensor.

On the bottom of VMT 107A there are support for mounting the sensor and 10-pole connector.
