SenSpot™ Wireless Structural Monitoring

SenSpot™ wireless structural monitoring sensors offer a breakthrough technology for real-time and long-term structural monitoring.

SenSpot™ is a complete wireless solution for remote structural monitoring consisting of 3 parts: SenSpot™, SeniMax™ & SenScope™:

SenSpot™

Sensor that is physically attached to structure. Used as many as needed, typically 10-200 per structure.

SenSpot™ sensors can be used to monitor:

  • Bridge piers and abutments – monitoring tilt, horizontal displacement, settling, deflection, instability of foundation
  • Structural elements – monitoring strain (stress) in girders, beams, truss members, detecting over-strain, fatigue
  • Bearings and expansion joints – monitoring bearing tilt, movement of joints, temperature response, detecting bearing malfunction
  • Bridge load rating – fast, easy, reliable load carrying capacity calculation assisted by strain response of bridge elements
  • Other structures – air frames, pipelines, tunnels, towers, buildings, cranes, etc.

SeniMax™

Collects data from on-site SenSpot™ sensors and sends it to a remote server (one unit can cover up to 250 SenSpot™).

SeniMax™ is a high performance wireless data collector and remote communication gateway designed for years of uninterrupted and reliable monitoring. SeniMax™ uses Resensys’s proprietary breakthrough energy efficient communication and scheduling technology. As a result, even when it is disconnected from solar cells, it still has a full month of energy reserve for reliable operation.

SeniMax™ has the option to interface with Cellular (HSPA/CDMA/GPRS), Wi-Fi, Ethernet, and satellite services.

SenScope™

Software package that analyzes data & generates alerts. SenScope™ is a software package for real-time monitoring and structural diagnosis. SenScope™ is capable of converting large volumes of data into specific structural diagnostics information. The information generated by SenScope™ facilitates decision making and accelerates the course of action for maintenance/repair.

Other types of SenSpot™ includes:

  • Wireless Strain Gauge SenSpot™
  • Wireless Displacement/Crack meter SenSpot™
  • Wireless Humidity and Temperature SenSpot™
  • Wireless Tilt/Inclination SenSpot™
  • Wireless Vibration/Acceleration SenSpot™
  • Wireless Anemometer SenSpot™
