Crack sensor
Used to monitor structural movement including pile separation, crack movement and expansion joint movement.
The crack sensor node connects to a linear displacement sensor. It is high-precision sampling circuitry that drives the sensor and reports its measurements via Senceive's wireless communication network to a gateway. It has been successfully used in many applications, including those measuring:
- Crack motion
- Pole separation
- Structural movement
- Joint monitoring of enlargement
Features
- Watertight, robust connectors for easy installation
- Automatic sensor type detection
- Extremely low sound performance
- 16-bit resolution (65,536 steps across the full scale)
- Integrated long life battery
- 12-15 year battery life
- Internal temperature sensor
- One and two channel variants offered as standard
- Waterproof to IP66 / IP67 / IP68
- Various mounts available for easy on-site installation
FlatMesh crack sensor node - FM3N-CS and GeoWAN crack sensor node - LR3N-CS
