Description

High-Stability Barometric Pressure Monitoring for Structural and GNSS Applications

Setra Model 278 is a high-accuracy barometric pressure sensor
designed for continuous environmental monitoring in Structural Health Monitoring
(SHM) and infrastructure monitoring systems.

Atmospheric pressure variations influence GNSS positioning, long-span structures,
and dynamic structural response. Reliable barometric pressure data provides
critical environmental context for interpreting displacement, vibration, and
tilt measurements.

Measured Parameters

• Atmospheric (barometric) pressure
• Long-term pressure trends

Sensor Capabilities

• High measurement accuracy and long-term stability
• Low drift performance for permanent installations
• Designed for continuous 24/7 operation
• Industrial-grade enclosure

Data Output & Integration

• Industrial analog output interfaces (model-dependent)
• Suitable for continuous environmental data logging
• Compatible with GNSS and SHM monitoring platforms
• Designed for permanent installation

Typical Applications

• GNSS reference stations
• Long-span bridges and large structures
• High-rise buildings
• Infrastructure monitoring systems

infrascan Integration

Setra 278 sensors are integrated into InfraScan monitoring systems to provide
barometric pressure data used for environmental compensation and improved
interpretation of GNSS displacement and structural response measurements.

These sensors are typically deployed alongside temperature, humidity, and wind
sensors to form a complete environmental reference layer.
