Description

Ultrasonic Wind Monitoring for Interpretation of Structural Dynamics

Vaisala WMT52 is a solid-state ultrasonic wind sensor designed for
accurate real-time measurement of wind speed and wind direction in structural
and infrastructure monitoring applications.

Wind is a primary external excitation source for vibration, tilt, and dynamic
response in tall and exposed structures. Reliable wind data is essential for
correlating measured structural behavior with environmental loading and
distinguishing normal wind-induced response from abnormal structural conditions.

Measured Parameters

• Wind speed
• Wind direction

Sensor Capabilities

• Ultrasonic measurement principle with no moving parts
• High reliability for long-term outdoor installations
• Fast response suitable for dynamic load correlation
• Designed for continuous 24/7 operation

Data Output & Integration

• Industrial digital and analog output interfaces (model-dependent)
• Suitable for continuous environmental data logging
• Compatible with structural monitoring and SHM platforms
• Permanent installation on buildings and exposed structures

Typical Applications

• High-rise buildings
• Bridges and long-span structures
• Towers, masts, and stacks
• Offshore and coastal infrastructure

infrascan Integration

Vaisala WMT52 wind sensors are integrated into InfraScan monitoring systems to
correlate wind conditions with vibration and tilt response, enabling accurate
interpretation of structural dynamics and environmental loading effects.

These sensors are typically deployed alongside vibration accelerometers,
tilt sensors, and GNSS displacement monitoring to build a complete dynamic
monitoring architecture.
