Description

Rugged Structural Temperature Monitoring for SHM Applications

OMEGA PR-21 RTD Temperature Sensor is a robust industrial temperature
sensor designed for continuous monitoring of surface and material temperature
in structural and infrastructure applications.

Unlike ambient air temperature sensors, surface and embedded temperature
measurements are critical for understanding thermal expansion, contraction,
and stress development in concrete, steel, and foundation elements.

Measured Parameters

• Surface or material temperature
• Long-term thermal trends

Sensor Capabilities

• RTD-based temperature sensing (Pt100 / Pt1000)
• High measurement stability and repeatability
• Rugged stainless-steel probe construction
• Suitable for harsh industrial and outdoor environments
• Continuous 24/7 operation

Data Output & Integration

• RTD output for direct connection to data loggers or monitoring systems
• Compatible with industrial temperature transmitters
• Suitable for permanent installation on structural elements

Typical Applications

• Concrete and steel structures
• Equipment foundations and slabs
• Retaining walls and structural elements
• Industrial and civil infrastructure

infrascan Integration

OMEGA PR-21 sensors are integrated into InfraScan monitoring systems to provide
direct structural temperature measurements used for thermal compensation and
interpretation of tilt, displacement, crack, and vibration data.

These sensors are typically deployed alongside ambient temperature and humidity
sensors to build a complete environmental reference layer for SHM projects.
