Wind speed and direction sensor KVT 60A
KVT60A is a combined rotation sensor for wind speed and wind direction.
- 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
KVT60A is made of naturally anodized aluminium.
For the wind speed sensor, a three-cup Robinson's cross is used, which, with a perforated rotated disc and optoelectonic transducer gives frequency proportional to the wind speed.
For the wind direction part of the sensor, a square rudder is mounted outside, and inside on the axis, a coding disc is fixed. In combination with the optoelectronic elements, this gives coded wind direction data. The six channel Gray's angle coding system is used in the directional part of the transmitter.
On the top of the wind speed axis there is a ertalyte radial bearing and on the bottom there is a double sapphire bearing. The directional axis is mounted on two ball bearings.
The electronic elements are protected from overvoltage by resistors and zener diodes. The normal additional load (icing) cannot damage the transmitter.
On the bottom of the sensor there is an aperture of 25 mm in diameter and 40 mm in depth for mounting the sensor. There is also a ten pin waterproof connector. The sensor can be delivered with wind tunnel calibration.
