Sliding micrometer (GM) measuring tube

The sliding micrometer measuring line is formed by the measuring tubes installed in the ground, rock or structure.

The measuring tubes consist of telescopic couplings and connecting tubes. Standard connecting tubes are made of HPVC, steel or stainless steel, depending on the application. The connection between the telescopic coupling and the capillary tube can be made watertight under pressure.

Sliding micrometer measurements are sometimes combined with borehole inclinometer measurements to determine not only the axial displacements but the entire displacement vector. In addition to sliding micrometer measuring tubes, Solexperts also offers tubes for combined measurements with the borehole inclinometer.
