Wind direction - Compact type

Wind vane anemometer with 0-1 Vcc output generated by Hall effect transducer

------

With compact size and high mechanical strength, DDNA212 sensor is particularly suiited for use in strong wind applications, where long term reliability without maintenance is required, as in wind farms and wind turbine surveys. Ideal also for portable and light AWS and for wind-alarm applications where wind speed and direction are both important issues. On this regard, LSI LASTEM data loggers can detect specific alarm conditions and open digital outputs when wind speed is over a programmable value and wind direction is coming from a defined angle.

-------

Highlights

      -  Completly made in anodized aluminium assuring long life time with high protection grade to

          severe weather conditions and strong winds

      -   0÷1V output. 10÷30 Vdc power supply

      -   High precision magnetic encoder for true full 0-360° measurement range.

      -   Supplied with water-proof free connector (3-wires+ground) for easy connection to cable

Wind Direction - Standard type - direct and analog output

Range of wind direction sensors. Analog and Ohm outputs

------

Wind direction sensor with analogue outputs. These wind vanes are ideal when requirements calls for simple integration with third-parties systems. DNA301.1-311.1 thanks to the 0-1 V output are ideal to be connected also to LSI-LASTEM’s acqui-sition systems. Low Delay Distance values and high precisiong magnetic encoder allow to obtain good accuracy even at very low wind speed conditions. DNA311.1-DNA811-815 version are equipped with heaters to avoid ice formation on their body in very cold environments.

------

Highlights

      -  Analogue outputs: 0÷1/5 V, 0/4÷20 mA.

      -  Very good values of Delay Distance and Damping ratio, according to VDI3786 and ASTM 5096-96

          standards

      -  Heated version for cold weathers

      -  Completly made in anodized aluminium assuring long life time with high protection grade to

          severe weather conditions and strong winds

       -  Protected bearings to avoid water and dirtness to access inside the their camera. This avoid to

          replace the bearings along the whole sensor life.
