Vibrating wire crack meter

The vibrating wire crack meter is used for the continuous measurement of the evolution of the structural opening joints, cracks and construction joints in concrete.
The tool is constituted of a cylindrical body inside which is housed the displacement transducer and a sliding rod connected to the same vibrating wire transducer translates the movements (widening or narrowing) of the slot to be monitored into an differencial frequency.
The two ends of the sensor are fixed, by means of blocks, straddling the same crack.
It can have different measuring ranges depending on the type of application.
To evaluate the three-dimensional movement of the crack, you can install the crack meter arranged in three main directions. (x-y-z).
