WS600-UMB compact weather station measures air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, air pressure, wind direction, and wind speed. Relative humidity is measured by a capacitive sensor element while a precision NTC measuring element measures air temperature.

The WS line of weather stations (including the economical WS200 ultrasonic anemometer) are now available with built in SDI-12 communication protocol, says LUFFT USA. Its weather stations and anemometers are now plug and play with any SDI-12 ready datalogger.  Lufft Intelligent Weather Stations and Anemometers still have the same

Cup anemometers or ultrasonic versions: Which works best where icing is worst? That is the questions to be answered after a 12 month study by Windpole LLC.

Windpole Ventures LLC of Arlington, Mass. has teamed with Garrad Hassan Americas to conduct a twelve month comparative study of ultrasonic and cup anemometers. The test will take place at locations in Illinois, Iowa, and Indiana, where winter-anemometer icing can be severe.

Both sensors will be unheated during the test. Boom configuration will be standardized and recommended by the third-party engineering firm.

The Aurora PVI-7200 W Wind Interface is intended for turbines with a max 7.2 kW output.

The power conversion efficiency rating of the Aurora Wind Interface model PVI-7200 W is 99.4%. It accepts three-phase input from a permanent-magnet generator (PMG) and outputs a max 7,200 W. The inverter has a fused wind input feature and an automatic brake function for the maximum 530 Vdc and an optional external brake resistor is available.
The PVI-7200 W, manufactured by Power-one, accepts an input of 0 to 400 Vac, an operating
