Vibrating wire sensors

Please contact us for any datasheet you need:

The vibrating wire sensors (first introduced in France by engineer André Coyne) measure different physical quantities (pressure, deformation, stress, force, inclination and displacement) of a work item by measuring the frequency variation of a wire stretched inside the body of the sensors.


In-situ measurement of the visco-elastic properties of the concrete.


Corrosion resistant Vibrating Wire Sensor for Pressure


Extensometer Vibrating Wire Sensor for siding joints and cracks.


Extensometer Vibrating Wire resistant to radiation.

These sensors, still often called audible indicators are used in the auscultation of Civil Engineering works. They have a reputation of being extremely reliable and can reach lifespans of over fifty years. Cementys develops a multitude of vibrating string sensors


Water content and temperature sensor.
