Construction Monitoring with Vibrating Wire

A vib wire sensor measures forces using a wire that vibrates at a high frequency. The applied external force changes the tension on the wire, this changes the frequency. The frequency is measured and indicates the amount of force on the sensor. A build-in thermistor is used to compensate thermal effects in the sensor. For data acquisition the system “plugs” the wire with a coil like a guitar string and then “listen” to the sound. The measurement data are acquired as micro strain.
