Scour is recognized as the leading cause of bridge failure in the United States, with 58% of bridge failures due to hydraulic conditions, according to the Federal Highway Administration (FHWA) and the National Bridge Failure Database. Effective monitoring of scour critical bridges is important to ensure their safety and longevity, especially during and after severe flood events.
Resensys provides cutting-edge wireless technology and tools designed to meet the specific needs of scour critical bridges. The system contributes real-time data on water levels, soil erosion, and bridge movement, enabling proactive measures to protect bridge.
Our solutions offer a range of benefits that make monitoring more efficient, reliable, and cost-effective:
•
Wireless Sensors and Devices: No wiring required, minimizing lane closures during installation.•
Maintenance-Free Sensors: 10+ years of battery life without the need for replacement, maintenance, or calibration.•
Easy Installation: Self-adhesive for steel or flange-mounting for concrete.•
Small and Lightweight: Compact sensors suitable for various materials, including steel, concrete, timber, and composites.•
Rugged and Weatherproof: Designed to operate in harsh conditions such as rain, snow, ice, high humidity, and extreme temperatures (-40°C to +65°C or -40°F to +150°F).•
Long Communication Range: Wireless communication up to 1 km in free space.•
High Precision Measurements:
1. Water Level Meter: High resolution of 0.1 ft (3 cm) for accurate water level monitoring.
2. Tilt/Inclinometer SenSpot™: Extremely high resolution of 0.00016 degrees (0.5 arcseconds) for precise inclination monitoring.•
Infrastructure-Free: Battery-operated and energy self-sufficient, with no need for additional communication infrastructure at the bridge site.
This system not only reduces installation costs and time but also provides real-time data critical for monitoring scour-prone bridges. The ultra-low power usage of Resensys sensors allows for both short and long-term monitoring, providing continuous safety.
Moreover, Resensys offers the option to integrate Wireless Solar Powered Cameras with the system. This combination allows for complete condition awareness through visual feeds, enabling quick assessments after severe floods and improving overall remote monitoring capabilities.
Our wireless monitoring system utilizes a combination of sensors to provide a holistic view of scour conditions:
Wireless SenSpot™ Sensors and Devices: These are strategically attached to scour-critical structural members. The number of sensors required depends on the bridge’s design, existing issues, and monitoring needs. Key sensors include:
- Wireless Tilt/Inclination SenSpot™
- Wireless Ultrasonic Water Level Meter SenSpot™
- Wireless Solar Powered Camera
SeniMax™: A wireless data logger gateway that collects SenSpot™ sensor data on-site and transmits it to a cloud database server via cellular or satellite networks. One SeniMax™ can support up to 100 SenSpot™ sensors within its communication range.
SenScope™: This powerful tool offers data analysis, visualization, export, automated alert management, and scour critical bridge data analysis. It also provides real-time alerts via email or text when pre-set thresholds are exceeded, ensuring timely responses to potential issues.
