Description

The Wireless Enhanced Strain Gauge IoT SenSpot™ by Resensys is a stand-alone product and cost-effective solution for distributed structural integrity monitoring. This wireless IoT strain gauge sensor measures data from two separate strain gauges and features an easy installation with either flange or adhesive mounts. Equipped with a high-capacity lithium-ion battery charged by a solar panel, it operates maintenance-free.

Based on the SeniMax™ Lite architecture, IoT SenSpot™ sensors can be applied easily to as many critical spots on a structure as needed with minimal installation effort.

With its robust design and IP68 weatherproof protection, it is ideal for strain monitoring in outdoor and hard-to-reach locations. The strain gauge IoT sensor uses a Nano SIM card with 4G LTE for remote data transmission without needing an intermediate device for sending the data, reducing overall project costs, especially for smaller projects.

 

Benefits of Wireless IoT Strain Gauge Sensor

  • Stand-alone IoT Device: all-in-one device capable of sensing, collecting, and uploading data to the remote server.
  • Robust design: IP68, weatherproof and durable for harsh environments.
  • Long battery life: Solar-powered operation for extended service life.
  • High accuracy: Precise displacement measurements for critical applications.
  • Real-time data: Instant access to displacement data for informed decision-making.

Featured Applications

  • Structural Health Monitoring: Assess the structural integrity of bridges, buildings, dams, tunnels, Storage Tanks & Silos and other critical infrastructure.
  • Bridge Health Monitoring: Monitor bridge expansion joints, bearings, crack formation and timber structures.
  • Civil Infrastructure Monitoring: Monitor displacement in railways and retaining walls.
  • Construction Monitoring: Monitor the stability of construction sites and structures.
  • Wind Turbine Monitoring: Monitors tower foundation for performance and safety.
