The Vaisala WINDCAP WMT700 ultrasonic wind sensor detects the wind speed and direction, and sends the measurement results to the data acquisition systems. WMT700 is a part of Vaisala's meteorological data measurement offering, and it is suitable for both system-based and stand-alone use. In stand-alone installation WMT700 must be equipped with a PJB480 power box.

The WMT700 series consists of 4 product models 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 build-up 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 neither degrades 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 prevention kit, a zero wind verifier, mounting adapters, and cables.
