  • Page 28: Functional Description

    ✔ ✔ The transmitters use Vaisala WINDCAP sensor technology for wind measurement. The wind sensor has an array of three equally spaced ultrasonic transducers on a horizontal plane. The unit determines wind speed and wind directions by measuring the time it takes the ultrasound to travel from one transducer to the other two.

  • Page 29: Precipitation Measurement Principle

    ✔ ✔ ✔ The transmitter uses Vaisala RAINCAP Sensor 2-technology in precipitation measurement. The precipitation sensor comprises of a steel cover and a piezoelectrical sensor mounted on the bottom surface of the cover. The precipitation sensor detects the impact of individual raindrops. The signals from the impact are proportional to the volume of the drops.

  • Page 30: Ptu Measurement Principle

    Chapter 3 – Functional Description Precipitation current intensity is internally updated every 10 seconds and represents the intensity during the one minute period before requesting/automatic precipitation message sending (for fast reactions to a rain event, during the first minute of the rain event, the intensity is calculated over the period rain has lasted in 10-second steps instead of a fixed period of one minute).

  • Page 35: Figure 16 Recommended Mast Location In Open Area

    WXT530 Series User Guide M211840EN-D Following World Meteorological Organization (WMO) guidelines, a general recommendation is that there is at least 150 m open area in all directions from the mast. Any object of height (h) does not significantly disturb wind measurement at a minimum distance of 10 times the height of the object.

  • Page 36: Figure 17 Recommended Mast Length On Top Of Building

    Additional protection is needed in regions with frequent, severe thunderstorms, especially when long line cables (> 30 m) are used. Vaisala recommends using a surge protector, such as WSP150 and WSP152, in all sites with an elevated risk of lightning strike.
