Mechanical 3D Deformometer

The mechanical 3D joint meter is a very simple and extremely strong instrument that allows automatic or manual measurement of the movements of cracks or joints in concrete and rock, in the three directions X, Y, Z.

The 3D deformometer consists of two steel elements (3D block), positioned either side of a crack, on which three linear displacement transducers of vibrating wire can be applied.

The vibrating wire 3D joint meter can be read either with our portable units (DEC 3000 and DEC 5) or with our dataloggers (CUM3000, VW hub 2, VW hub 8, CRio VW). Manual reading by analog or digital dial gauge is always possible.

Our joint meters can be integrated into automatic monitoring systems and manage phenomena and alarms locally and remotely in real time.

For specific needs and requests, we are able to develop and manufacture customized products different to standard.

Applications

Normally used with:
-Slots
-Joints
-Dams
-Bridges
-Galleries
-Buildings
-Viaducts
-Rock

Features and Benefits

-Simple
-Sturdy
-Able to perform measurements in both automatic and manually
-Made of stainless steel

Measurement Principle

The 3D deformometer is made entirely of stainless steel, it is constituted of two separate parts, applied to the two adjacent blocks whose movements are to be measured.
Measurement is performed manually or with comparator gauge, or automatically by applying vibrating string transducers or other types of sensors on request.
Manual and automatic measurement instruments are supplied separately.
