GENERAL

Biral's mechanical cup and vane wind speed and wind direction sensors are industrial grade instruments manufactured by Thies Clima who have over 50 years experience and supply sensors to national weather services and the WMO (World Meteorological Organisation).

Cup and vane sensors are the traditional method of measuring wind and generally all cup and vane sensors should have the following features:

• reliable measurement of horizontal wind speed and direction
• sensitive to small fluctuations in wind speed
• low maintenance
• provides good repeatability of data and decent error accuracy
• models are available with digital and analogue interfaces
• can be interfaced / adapted to existing systems

In addition the Thies Clima cup and vane sensors from Biral also feature:

• free-flowing due to high quality bearing systems
• data can be polled, output automatically or averaged
• First Class series sensors has a rugged, durable aluminium construction suitable for all environments
• Compact series sensors provide excellent cost / performance ratio
• Heating is available on most models
• high heating efficiency, where relatively low power input is needed as only the key areas are heated when required which also avoids unnecessary power loss
• various output configurations are available for volume orders
