Sentrex Wind Services Inc., is a Canadian company providing services to the wind energy industry. We take pride in providing our clients with a one-stop service centre for their wind assessment needs.

Whether you are a wind developer, turbine manufacturer or any other party with a need to characterize the wind, we have a team of professionals ready to assist in making your project a success.

The Sentrex field crew has extensive experience in installing, maintaining, and decommissioning both tubular and lattice towers.
results. Careful attention is paid to every detail when commissioning and decommissioning components, whether they are delicate wind instruments requiring precise installation and alignment, or large communication antennas.

We have a mobile crew with remote site experience willing to travel to any location to meet and exceed the needs of our clients.

Instrumentation installation and data-logger programming are also provided for Renewable NRG Systems, Vaisala, Campbell Scientific and other vendors.

In addition to basic programming for these data-loggers, we also provide advanced programming and configuration support for Campbell Scientific measurement and control data-loggers. This includes control of various transducers, such as motors and solenoids. Contact our engineers for your specialization needs.

We have in-house expertise in all types of wind measurement instrumentation (all makes of anemometers and vanes, including Renewable NRG sensors, WindSensor, Vector, Vaisala, Thies, Ornytion, RMY and more).

SODAR is a wind measurement technology based on sonic detection and ranging. It provides a “virtual met tower” up to 200m in height and does so by emitting audible “chirps” up into the air. By then measuring the time delay, intensity and Doppler shift of the returned signal, the Wind Finder can provide a clear profile of the wind at that specific site.

AQ SODAR WIND FINDER

We are now pleased to offer our clients installation, maintenance and data analysis for the AQ Wind Finder, which offers several advantages to other wind measurement technologies. AQSystem have been Europe’s leading wind industry sodar manufacturer for over ten years.

ADVANTAGES OF AQ SODAR

• Dedicated speakers for each beam direction for tight focus and high accuracy
• More power per beam allowing for a high availability of data at all levels in more atmospheric conditions
• 5m vertical resolution from 40m to 200m (data every 40m, 45m, 50m…)
• Accurate Turbulence Intensity (TI) measurements with high data availability
• Reliable diesel based power and heating systems. Proven by hundreds of deployments through Scandinavian winter conditions over many years.
• No annual fee for online data access
• Intuitive online interface with graphical representation of data
• AQ510 performance has been independently verified by many leading wind consultancies including DNV-GL (Garrad Hassan and is the only sodar to have been independently verified as capable to meet the stringent requirements of draft standard IEC 61400‐12‐1 rev 2.

ADVANTAGES OF REMOTE SENSING

What are the advantages of SODAR?

• Mobile and easily deployed.
• Can be used to “extend” an existing met tower to hub height or beyond through measurement and correlation.
• Can produce a wind profile across the rotor, and provides information on wind veer in addition to wind shear.
• Profiles are based on observation instead of extrapolation.
• Vertical wind measurements provide information about turbulence and upflow or downflow conditions.
• Provides a tool for confirming wind flow models in complex terrain.
• Provides output data in an easy to use “virtual met mast” format.
