WMT50 Ultrasonic Wind Sensor for Accurate and Stable Measurement

Proven Vaisala performance

The Vaisala WINDCAP® Ultrasonic Wind Sensor WMT50 incorporates Vaisala’ s decades of experience in wind measurement using ultrasound to determine horizontal wind speed and direction.

Accurate measurement

The triangular design in the WMT50 solves the mechanical shading of transducers on measurement paths. This ensures accurate wind measurement from all wind directions, without blind angles or corrupted readings.The WMT50 is free from problems the conventional mechanical sensors often have such as inertia, friction, time-constant, over-speeding, and starting threshold.

Easy settings

The WMT50 is supplied pre-configured from the factory. With the Vaisala Configuration Tool you can change the settings, such as averaging times, output mode, update intervals, measured variables, and message contents.

Heating

Wind can also be measured in freezing weather and during snowfall, thanks to the optional heating available in the WMT50. As the heating circuit is separate from the operational power, separate supplies can be used. Heating is switched on automatically only at low temperatures.

Flexible output options

The WMT50 communicates with the host via a bi-directional serial line. It offers a choice of four configurable serial interfaces: SDI-12, RS-232, RS-485, and RS-422. The screw terminals inside the lower part of the transmitter are easy to access. An industry standard 8-pin M12 connector is optionally available.
