Vibrating wire sensor node
Our vibrating wire sensor interface enables high precision and low power monitoring of a wide range of structural and geotechnical sensors.
The Vibrating Wire Sensor Interface Series provides a wide range of vibrating wire sensors to our systems. It is a highly integrated system that can excite and sample vibrating wire sensors and report measurements via Sencive's wireless communication network to a gateway.
Example of supported sensors:
- Piezometers
- Strain gauge
- Load and pressure cells
- On site inclinometers
- External temperature
- Extensometers
- Crack gauge
- Sensors for soil moisture
Features
- High-performance, easy-to-connect multi-channel connectors
- Watertight, robust connectors for easy installation
- Resolution of 0.001 Hz and repeatability of ±0.02 Hz
- Integrated long life battery
- 10-15 year battery life, including when acting as a relay node in the mesh communication network
- Integrated temperature sensor
- Versatile mounting options
- Waterproof to IP66 / IP67 / IP68
- Firmware can be remotely upgraded via the gateway, which reduces costly site visits (FlatMesh)
- Supports an NTC sensor on each connector
- 1 and 4 channel versions available
