The MicroVib© sensor is designed to measure locally the total deformations undergone by concrete (shrinkage deformations, thermal deformations, pathological swellings, mechanical deformations) or steel.

logo-trust-techSensors for strain and stress measurements

The MicroVib© sensor is designed to measure locally the total deformations
undergone by concrete (shrinkage deformations, thermal deformations, pathological
swellings, mechanical deformations) or steel.

The measurement is based on the proven vibrating rope technology, which guarantees
maintenance-free monitoring with long rope lengths and over long periods.
The MicroVib© sensor consists of a flexible monolithic test body, which has two
cheeks defining the measurement length. The measurement of this frequency can
be carried out over large wiring distances.
The MicroVibRR© version is made of radiation resistant materials.
