Crack Sensor Node

The Crack Sensor Node is used to monitor structural movement including pile separation, crack movement and expansion joint movement.

The Crack Sensor Node interfaces to a linear displacement sensor. It’s high precision sampling circuit powers the sensor and reports its measurements through Senceive’s wireless communications network to a Gateway. It has been successfully used in many applications, including those measuring:

  • Crack movement
  • Pile separation
  • Structural movement
  • Expansion joint monitoring
