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 brings 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.
Examples of supported sensors:
- Piezometers
- Strain gauge
- Load and pressure cells
- On-site inclinometers
- External temperature
- Extensometers
- Crack gauge
- Soil moisture sensors
Features
- High-performance, easy-to-connect multi-channel connectors
- Waterproof, robust connectors for easy installation
- Resolution of 0.001 Hz and repeatability of ±0.02 Hz
- Integrated long-life battery
- 10-15 years of 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 upgraded remotely via the gateway, reducing costly site visits (FlatMesh)
- Supports one NTC sensor on each contact
- 1 and 4 channel versions available
