Product Description
Wind Measurement
Both wind speed and direction are measured using the advanced Vaisala WINDCAP Sensor. The sensor uses ultrasound to determine horizontal wind speed and direction. The array of three equally spaced ultrasonic transducers on a horizontal plane is an ideal, Vaisala proprietary design. The design ensures accurate wind
measurement from all wind directions, without blind angles or corrupted readings.
The wind sensor has no moving parts, which makes it maintenance free. The measurement range for wind speed is from 0 to 60 m/s and for wind direction from 0 to 360 degrees.
Precipitation Measurement
The precipitation measurement is based on the Vaisala RAINCAP Sensor, which detects the impact of individual rain drops. The signals exerting from the impacts are proportional to the volume of the drops. Hence, the signal from each drop can be converted directly to the accumulated rainfall.
Compared to traditional precipitation gauges, the Vaisala RAINCAP Sensor gives more detailed information about precipitation. The WXT510 measures accumulated rainfall, rain intensity and duration of the rain all in real time. Due to the measurement method, flooding, clogging as well as wetting and evaporation losses in rain measurement are eliminated.
The Vaisala RAINCAP Sensor is the only maintenance free precipitation sensor on the market.
PTU module for barometric pressure temperature and humidity
Barometric pressure, temperature and humidity measurements are combined in an advanced PTU module utilizing capacitive measurement method for each parameter.
Barometric pressure is measured using the silicon-based Vaisala BAROCAP Sensor. The sensor has minimal hysteresis and excellent repeatability, as well as outstanding temperature and long-term stability. The measurement range for pressure is from 600 to 1100 hPa.
Temperature measurement is based on the ceramic Vaisala THERMOCAP Sensor. The measurement range is from -52 to +60 C.
Humidity measurement is based on the Vaisala HUMICAP technology. The Vaisala HUMICAP Sensor is highly accurate and it offers excellent longterm stability in a wide range of environments and negligible hysteresis. The measurement range for humidity is 0...100 %RH.
The whole PTU module is replaceable and available as a spare part.
Accurate and Stable Measurement
The PTU module is mounted in a specially designed radiation shield. The shield protects the sensors from both scattered and direct solar radiation and
precipitation. The plastic material in the plates offers excellent thermal
characteristics and UV stabilized construction. The white outer surface
reflects radiation, while the black inside absorbs accumulated heat.
