Warning alerts you to a serious hazard. If you do not read and follow
instructions very carefully at this point, there is a risk of injury or even
death.
Caution warns you of a potential hazard. If you do not read and follow
instructions carefully at this point, the product could be damaged or
important data could be lost.
Note highlights important information on using the product.
To protect personnel (and the wind sensor)
installed with the tip at least one meter above WMT700. The rod must be
properly grounded, compliant with all local applicable safety regulations.
Do not install the wind sensor above the top of the lightning protection
rod.
If ice or snow accumulates on WMT700 or the mast, it can fall and cause
injury to persons below.
Some WMT700 product versions provide heating for transducers and/or
array arms. To avoid injury, do not touch the heated parts of the wind

CHAPTER 2
PRODUCT OVERVIE W
This chapter introduces the features, advantages, and product
nomenclature of 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 standalone 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 and the sensor body from ice and snow
buildups 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 user also has a wide range of configuration options
for the wind sensor and the 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.

Ordering Options
A WMT700 unit can be configured by ordering options to suit
versatile customer needs. You can reconfigure the following
options:
- Digital communication interface
- Digital communication profile
- Digital communication units
- Analog output signals for wind speed channel
- Analog output signals for wind direction channel
Measurement Range
Ordering option 1, Measurement Range, defines the wind speed
operation range for the sensor. The maximum reported value of
wind speed 40, 65, or 75 m/s, depending on the selected option as
shown in Table 5 below.
Table 5 Measurement Ranges of Different Sensor Types
Temperature Range
Ordering option 2, Temperature Range, defines the operating
temperature range for the sensor as shown in Table 6 below.
Table 6 Temperature Ranges
Note that the temperature range is not connected to heating in any
way. If you operate in a demanding environmental climate where
ice accumulation is expected, Vaisala recommends that you use a
heated sensor; see Option 4 in Table 7 on page 24.
