WMT52 Ultrasonic Wind Sensor for
Accurate and Stable Measurement
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.
The Vaisala WINDCAP
®
Ultrasonic Wind Sensor WMT52 - stable and inexpensive
wind measurement for demanding applications.
Applications
The WMT52 is ideal for use in marine
applications as the housing with
the mounting kit is water resistant.
The WMT52 is also suitable for
wind energy and environmental
monitoring, for example, for
measuring the distribution of air
pollution and road tunnel ventilation.
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.
Heating
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.
Low power consumption
The WMT52 has very low power
consumption; during the idle mode
the device typically consumes about
2 ... 3 mW.
