|Modèle :||WMT700 WINDCAP®|
|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.|
Accurate and Maintenance-free
The WMT700 series has a durable full steel structure with welded arms, clear north indication, and one-point, quick bayonet-style mounting. It has has no moving parts, and it is resistant to contamination and corrosion.
Measurement Based on Ultrasound
The 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.
Standard and Heated Models
The sensor 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.
|Easy to install|
The WMT52 is delivered fully assembled and configured from the factory. With the Vaisala Configuration Software Tool you can change the settings, such as averaging times, output mode, update intervals, measured variables and message contents.
The WMT52 can be mounted either on top of a pole mast or on a cross arm.
When using the optional mounting kit, the north alignment needs to be performed only once.
The optional heating available in the WMT52 assists measurements in the freezing weather conditions and during snowfall.
As the heating circuit is independent of the operational power, separate supplies can be used. Heating is switched on automatically at low temperatures, well before the freezing point.
|Proven Vaisala performance|
The Vaisala WINDCAP® Ultrasonic Wind Sensor WMT52 incorporates decades of Vaisala experience in wind measurement using ultrasound to determine horizontal wind speed and direction.
With no moving parts, the WMT52 has high sensitivity as the measurement time constant and starting threshold are virtually zero. This makes it superior to the conventional mechanical wind sensors.
The WMT52 is designed to operate without periodic field calibration and maintenance.
