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.

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
  • Tiltmeters
  • Crack gauges
  • Soil moisture sensors
