PRODUCT OVERVIEW
This chapter introduces the features, advantages, and the product
nomenclature of WMT701, WMT702, and WMT703.
NOTE
In this manual WMT700 series wind sensors WMT701, WMT702 and
WMT703 are commonly referred to as WMT700.
Introduction to WMT700
Vaisala WINDCAP
®
Ultrasonic Wind Sensor WMT700 measures wind
speed and direction and sends the measurement results to data acquisition
systems. WMT700 forms part of the Vaisala weather measurement
offering suitable for systems and stand-alone installations.
The WMT700 series consists of three product types with different
measurement ranges: WMT701, WMT702, and WMT703. Additionally,
you can select heating functions that shield the array and/or the
transducers from ice and snow build-ups 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 also fully compensated.
Since the WMT700 series 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 the customer's order,
and it is ready for operation directly after the installation. If required, the
