2. Product Overview Introduction to WMT700
WMT700 measures wind speed and direction, and sends the measurement results to data acquisition systems. WMT700 is suitable for systems and standalone installations.
The WMT700 series consists of four product types with different measurement ranges:
WMT701, WMT702, WMT703, and WMT704. You can select heating functions that shield the array and/or the transducers and the sensor body from ice and snow buildup in cold climates.
The WMT700 series wind sensors are based on the advanced, patented Vaisala WINDCAP
wind measurement technology that ensures accurate results in all wind directions. The effects of temperature, humidity, and pressure are fully compensated.
Since the wind sensors have no moving parts, they are virtually maintenance-free. The performance of the sensors does not degrade with wear nor is it affected by natural contaminants such as salt, dust, or sand.
The WMT700 series wind sensors support a wide range of communication options. You can connect the wind sensors directly to a variety of data acquisition systems without additional converters or adapters.
WMT700 is configured at the factory according to your order, and it is ready for operation directly after the installation. You also have a wide range of configuration options and measurement settings.
WMT700 can be equipped with accessories to tailor the instrument to match different user- specific needs. The accessories include a bird deterrent solution and a field-usable calibration verifier.
