WINDCAPâ Ultrasonic Wind Sensor WMT700 Series - 1

WINDCAP® Ultrasonic Wind Sensor WMT700 Series WMT700 Series has been designed for professional use in meteorology, aviation, maritime, wind energy, and many other applications. VAISALA Features • WMO and ICAO compliant • Data output rate 4 Hz and 8 Hz • Stainless steel structure • Maintenance-free • Three-transducer layout provides accurate data • Data format outputs: polar coordinates and vectors • Fully compensates effects of temperature, humidity, and pressure • Measurement range up to 90 m/s (201 mph) • Heating up to 250 W • IP66 and IP67 • Large transducers provide high ultrasound power • Optional bird prevention kit • Wind gust calculated according to the WMO guidelines • US National Weather Service and the FAA rely on Vaisala WINDCAP® technology Vaisala WINDCAP® Ultrasonic Wind Sensor WMT700 Series is a robust and reliable ultrasonic anemometer. It measures surface wind, which is one of the key parameters for meteorology and aviation. WMT700 series meets the updated -WMO-No.8 guide, 7th edition - and ICAO requirements. Accurate and Maintenance-free WMT700 series has a durable full steel structure with welded arms, clear North indication, and onepoint, quick bayonet-style mounting. It has no moving parts, and it is resistant to contamination and corrosion. It measures accurately and produces reliable data in demanding wind conditions and climates without periodic or on-demand maintenance. Selfdiagnostics and validation of measurement are standard features. The 60-minute average is available for polar coordinates and vectors. Measurement Based on Ultrasound WMT700 series uses ultrasound to determine horizontal wind speed and direction. The measurement is based on transit time, the time it takes for the ultrasound to travel from one transducer to another, depending on the wind speed. The transit time is measured in both directions for a pair of transducer heads. Using two measurements for each of the three ultrasonic paths at 60° angles to each other, WMT700 computes the wind speed and direction. The wind measurement is calculated in a way that completely eliminates the effects of altitude, temperature, and humidity. Standard and Heated Models WMT700 Series operates with a power supply of 9 ... 36 VDC. For the heated model, an additional heating power supply of 24 ... 36 VDC is required. Thermostatically controlled heaters in the transducer heads and arms of the heated model prevent build-up of freezing rain or snow. A model with a heated transducer, arms, and body is also available for operation in the harshest and coldest environments. In addition, accessories are available for mounting and connecting WMT700. To minimize interference from birds, a bird prevention kit is avail
