Sensor Interface / Crack Sensor Node
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
- Waterproof, robust connectors for simple installation
- Automatic sensor type detection
- Extremely low noise performance
- 16-bit resolution (65,536 steps over the full scale)
- Integrated long life battery
- 12-15 years’ battery life
- Internal temperature sensor
- One and two channel variants offered as standard
- Waterproof to IP66 / IP67 / IP68
- Variety of fixings available for easy installation on site
