Sensors for measuring wind speed and wind direction MS&E PISPV-4
Sensor MS&E PISPV-4 is in production list of the Consortium "MS&E" since the end of 2008 and is designed to measure speed and direction of the wind from automatic weather stations models MS&E-3, MS&E-4 and automatic anemometer MS&E DL Wind-2. It consist of bodies of aluminum alloy, impeller, wind vane from aluminum alloy and 10 m signal cable.
Sensor MS&E PISPV-4 is composed of two separate sensors: for wind speed and for wind direction. Sensors are provided with anti-icing heating, driven by electronic thermostats.
Transducers: Proximity – optocouplers
- Speed - frequency directly proportional to wind speed
- Direction - 7 bit parallel code of Gray;
Electronics for the sensors:
- DC, from 10 to 15V
- Current consumption at 12 V - 80 mA.
To heat sensors
- DC 12 to 20V
- Current consumption at 15 V - 2 A.
Metrological characteristics of the wind direction:
-Measuring range from 0 ° to 360 °;
-Resolution of <3 °;
-Absolute measurement error of - ± 1.5 ° including the error for finding the North
