Product Description

Overview

The Enviko SK-DMP series multi-point extensometers are installed directly in boreholes to monitor deformation or settlement across multiple slip surfaces and zones. Apart from the rod protection tubes and anchors, the instruments are made entirely of stainless steel. They offer high accuracy, a simple and shock-resistant construction, easy installation and stable long-term readings, and support long-distance transmission and automated monitoring. A built-in temperature sensor records the temperature at the installation point, and a smart ID chip can be fitted on request.

Key Features

2 to 6 measuring points in one borehole (borehole diameter ≥ 130 mm)
Stainless steel construction, except rod protection tubes and anchors
Waterproof to 2 MPa (up to 3 MPa on custom versions)
High accuracy with stable long-term readings
Good shock resistance and simple installation
Long-distance signal transmission and automated monitoring
Built-in temperature sensor; optional smart ID chip

Applications

Hydropower and water-conservancy projects
Mines and underground caverns
Railways and highways
Slopes
