Precision Wired Sensors for Structural Health Monitoring
High-precision accelerometers and strain gauges engineered for accurate, continuous monitoring of bridges, buildings, tunnels and industrial infrastructure — built for the harshest field conditions.
Benefits Built for Accuracy
From bridge decks under live traffic loads to industrial machinery experiencing high-frequency vibration — Sentra wired sensors deliver the data precision engineers rely on for confident structural health decisions.
High-Precision Detection
Capture minute vibrations and micro-strain with exceptional accuracy across a wide dynamic range — delivering comprehensive structural health assessment data.
Rugged & Reliable
IP67-rated weatherproof enclosures survive full immersion, extreme temperatures and harsh site conditions without signal degradation.
Predictive Analytics
AI-powered cloud analytics identify patterns and trends, enabling proactive maintenance before failures occur — reducing lifecycle costs significantly.
Easy Integration
Seamless connectivity with LoRaWAN, 4G LTE, RS-485 and Bluetooth. Integrates with existing SCADA, BIM and cloud platforms without reconfiguration.
What Makes Our Wired Sensors Different
Enterprise-grade hardware and software designed for mission-critical structural monitoring applications.
3-Axis MEMS Accelerometer
Captures acceleration across all three axes simultaneously with a ±16g range — ideal for vibration, seismic response and modal analysis on any structure type.
Strain Gauge Technology
Spot-weldable and 4100-series strain gauges for direct surface bonding on steel and concrete — measuring micro-strain under static and dynamic loading conditions.
Multi-Protocol Connectivity
Supports LoRaWAN for long-range wireless, 4G LTE for cellular backhaul, Bluetooth for local configuration and RS-485 for wired SCADA integration.
Cloud Analytics Platform
Real-time dashboards, historical trend analysis and automated threshold alerts accessible via web or mobile. BIM and GIS integration ready out of the box.
Real-Time Alerts
Configurable threshold-based alerts via SMS, email and push notifications — instant notification when sensor readings exceed safe operating parameters.
Long Battery Life
Up to 10 years on replaceable battery cells. AC/DC power input and solar panel options available for permanent installations requiring zero maintenance.
