Description

Reference-Grade Temperature & Humidity Monitoring for Structural Health Monitoring

Vaisala HMP7 is a high-accuracy industrial temperature and humidity
probe designed for long-term environmental monitoring in Structural Health
Monitoring (SHM) and infrastructure monitoring applications.

Ambient temperature and humidity are critical environmental parameters that
directly influence structural behavior, material response, and sensor readings.
Accurate and stable environmental reference data is essential for correct
interpretation of tilt, vibration, displacement, and crack monitoring results.

Measured Parameters

• Ambient air temperature
• Relative humidity

Sensor Capabilities

• High measurement accuracy and long-term stability
• Designed for permanent outdoor and industrial installations
• Excellent resistance to humidity drift and contamination
• Continuous 24/7 operation

Data Output & Integration

• Industrial analog and digital output interfaces (model-dependent)
• Suitable for continuous environmental data logging
• Compatible with monitoring dashboards and SHM platforms
• Designed for long-term unattended operation

Typical Applications

• Buildings and civil infrastructure
• Bridges, tunnels, and retaining structures
• Industrial facilities and outdoor installations
• Structural Health Monitoring reference stations

infrascan Integration

Vaisala HMP7 sensors are integrated into InfraScan monitoring systems as
reference-grade environmental inputs, providing essential context for
interpreting structural response and separating environmental effects from
true structural behavior.

These sensors are typically deployed as baseline environmental nodes and
combined with vibration, tilt, GNSS, and crack monitoring sensors to build
robust and interpretable SHM architectures.
