Frequently Asked Questions (FAQ)

Resensys Wireless Structural Health Monitoring Systems

General FAQs
Do Resensys systems support both temporary and permanent monitoring?

Yes. Resensys systems are designed for both short-term and long-term applications. They are widely used for:
• Proof and load testing
• Construction-phase monitoring
• Temporary structural assessments
• Post-event inspections (e.g., overloads, seismic events)
• Long-term structural health monitoring (SHM)
The ultra-low-power architecture makes them especially well-suited for permanent infrastructure monitoring.

How is data collected and accessed?

Sensor data is transmitted wirelessly to a local gateway. The gateway securely uploads data to Resensys’ monitoring platform, where users can:
• View real-time and historical data
• Monitor strain trends and load events
• Configure alerts and thresholds
• Download reports and export data
Remote access eliminates the need for frequent site visits.

Can Resensys systems integrate with existing monitoring platforms?

Yes. Resensys systems support integration with third-party platforms and legacy monitoring systems. Data can be shared via APIs or exported in standard engineering formats. Hybrid systems combining Resensys wireless sensors with conventional instruments are also supported.

Does Resensys provide support during project deployment?

Yes. Resensys provides:
• Application engineering support
• Installation guidance
• System configuration assistance
• Data interpretation support
• Training for field personnel
Our team works closely with clients to ensure accurate deployment and meaningful data interpretation.

Can Resensys systems be customized for specific projects?

Yes. System parameters can be customized to meet project requirements, including:
• Sampling rates (standard and burst modes)
• Triggering thresholds
• Measurement ranges
• Gauge types and orientations
• Environmental protection levels
Customization ensures alignment with structural type and monitoring objectives.

Wireless Strain Gauge Technology
What makes Resensys wireless strain gauges different from conventional wired gauges?

Resensys wireless strain gauges eliminate long cable runs, significantly reducing installation time, labor cost, and system complexity. Key advantages include:
• Ultra-low power consumption (multi-year battery life)
• Full-bridge sensing for improved temperature compensation
• High-resolution measurements
• Event-triggered burst sampling
• Minimal maintenance requirements
Wireless architecture also reduces vulnerability to cable damage and electrical noise.

How accurate are Resensys wireless strain gauges?

Resensys strain gauges use full-bridge sensing transducers that provide:
• High-resolution microstrain measurements, 1.0 microstrain resolution or betetr
• Automatic temperature compensation
• Stable long-term performance
• Minimal drift over time
Factory calibration ensures measurement reliability suitable for engineering-grade structural analysis.

How does temperature affect strain measurements?

Resensys full-bridge strain gauges are designed to cancel out uniform temperature changes.
If temperature variations induce actual mechanical strain in the structure (e.g., restrained expansion), that strain is accurately captured and reported. The system also monitors slow-varying thermal trends separately from dynamic load events.

What is burst mode sampling?

Resensys sensors operate in ultra-low-power monitoring mode but automatically switch to high-frequency burst sampling when a strain threshold is exceeded.
Burst mode typically records high-resolution data (e.g., ~20 samples per second), capturing events such as:
• Heavy truck loads
• Overweight vehicles
• Sudden structural responses
• Impact events
This approach ensures detailed event capture without draining battery life.

What is the expected battery life?

Depending on configuration and event frequency, battery life typically ranges from several years for permanent installations. Optimized power management and synchronized communication protocols maximize operational longevity.

Technology & System Design
How reliable is wireless data transmission in large infrastructure projects?

Resensys uses industrial-grade synchronized wireless communication designed for structural environments. The system:
• Supports long-range transmission
• Maintains stable communication across large bridges and structures
• Minimizes data loss through coordinated transmission timing
Gateway placement is optimized during project planning.

How is data accuracy maintained over long monitoring periods?

Accuracy is maintained through:
• Factory calibration
• Full-bridge temperature compensation
• Continuous sensor health diagnostics
• Automated offset correction algorithms
• Stable electronics design
The system is engineered for multi-year monitoring without recalibration requirements under normal operating conditions.

What types of structures can be monitored?

Resensys systems are widely used on:
• Highway and railway bridges
• Cable-stayed and suspension bridges
• Tunnels
• Buildings and high-rises
• Offshore and marine structures
• Industrial facilities
• Space and aerospace infrastructure

Installation & Deployment
How long does it typically take to install a Resensys monitoring system?

Individual wireless strain gauges can typically be installed in minutes per location. Complete deployment time depends on project size but is significantly faster than traditional wired systems due to:
• No conduit installation
• No centralized wiring
• Minimal cabling

What level of technical expertise is required?

Field technicians with basic technical training can perform installation. Resensys provides detailed documentation and support to ensure proper setup.

Can installation be done without lane closures?

In many cases, yes. Because the system is wireless and compact, sensors can often be installed from accessible locations, minimizing or eliminating traffic disruption.

Data & Software
Is historical data retained for long-term analysis?

Yes. The platform supports long-term storage and trend analysis, enabling:
• Seasonal behavior evaluation
• Fatigue assessment
• Load pattern studies
• Performance benchmarking

Can data be exported?

Yes. Data can be exported in formats suitable for:
• Engineering analysis
• Finite element model calibration
• Regulatory reporting
• Asset management systems

How secure is the monitoring data?

Resensys uses secure communication protocols and controlled access to protect system data. Network security and cloud security practices follow industry standards to ensure data integrity.

Future-Proofing & Scalability
Can additional sensors be added later?

Yes. The system is fully scalable. Additional sensors can be added without rewiring or major infrastructure changes.

Is the system adaptable to changing monitoring requirements?

Yes. Sampling intervals, triggering thresholds, and communication settings can be adjusted remotely to accommodate evolving project needs.

How does Resensys support long-term infrastructure resilience?

By continuously monitoring structural behavior, Resensys enables infrastructure owners to:
• Detect overload events
• Identify early signs of deterioration
• Reduce inspection frequency
• Extend asset service life
• Implement data-driven maintenance strategies
This proactive monitoring improves safety, reliability, and lifecycle management.
