Sensor Interface / Vibrating Wire Sensor Node
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 for use in variety of sectors.
The Vibrating Wire Sensor interface range brings a wide variety of vibrating wire sensors into our systems. It is a highly integrated system which is capable of exciting and sampling vibrating wire sensors and reporting measurements through Senceive’s wireless communications network to a gateway.
Examples of the sensors supported:
- Piezometers
- Strain gauges
- Load & pressure cells
- In place inclinometers
- External temperature
- Extensometers
- Crack gauges
- Soil moisture sensors
