Strain Sensor and Temperature, High Precision, Wireless RFID UHF EPC, Battery-Free or Data Logger for Structural Health Monitoring (SHM)

The SHM Strain Sensor can be read with a fixed RFID reader or hand held reader. The on-board non-volatile memory allows for long term historical measurement comparison that facilitates “at a glance” alarming changes in structure integrity.

Structural Health Monitoring Strain Gauge and Temperature Sensor

  • High Strain Sensitivity and Range.
    • +/- 250 micro-strain, 2 micro-strain resolution.
    • *Strain sensors are typically custom-configured for each application.  Contact us with your requirements.
  • Temperature Accuracy ±2°F (+/-1°C) typical. Greater accuracy is available at additional cost.
  • On-board temperature sensor can be used for strain compensation.  Precision temperature compensation available.
  • Read with a standard Intermec or ThingMagic UHF EPC RFID reader.
  • Wireless communication allows for multiple embedded installation options
    • metal mount
    • inside wall
    • inside concrete
  • Battery-free sensor allows for long life with no maintenance.
  • Data logger battery typically lasts for 10 years.  After the battery dies, the sensor can be read in a “read now” battery-free RFID mode.
  • Data logger can store 300 to 800 time-stamped readings.
  • On-board non-volatile read/write memory can store customized information about the sensor or structure.
  • Zero-offset, temperature compensated and time-stamped data.
  • Read multiple tags with one reader.
  • Small form factor for tight spaces or moving applications.
  • Custom versions available for specific environments.

This wireless sensor is ideal for monitoring:

  • Structural health including bridges, roads and chassis.

The system also features a “calibrate in place” feature that allows the installer to set a zero-offset after the strain sensor is adhered to the structure to be monitored.  Watch the video for a demonstration of this feature.
