Settlment and Displacement

Structural cracks, structural joints, rock fall etc.
The wire extensometer DS821 measures the displacements between two points placed horizontally or vertically, spaced from each other by a minimum of 0.5mt to a maximum of 10mt. The sensor is mounted on one of the points of interest and the end of the wire is fixed to an anchor placed on the other point. The DS821 model integrates a spring system that keeps the wire under tension once it is pulled and fixed. It is advisable to protect the wire with a protective tube to avoid damage. The standard mounting kits are of two types: one for vertical mounting and one for horizontal mounting. For specific cases, on request, it is possible to customize the mounting kit. The electrical transducer, available in standard measuring ranges between 100 and 8000mm, provides an electrical signal proportional to the displacement. Thanks to its sturdiness and protection IP65 they are particularly suited to an external mounting in harsh environment conditions, ensure high reliability. Wire extensometer has various technical configurations, based on: range (100…8000mm), supply-out (1…24Vcc) and output (mV/mA).
Every sensor is provided with a calibration certificate that attests the results of the test performed and all electromechanical features.
