In-place borehole inclinometer are instruments designed for automated monitoring of deformation and lateral displacements in soil and structures. They are intended for geotechnical and civil engineering applications in highly critical environments. Each in-place inclinometer consists of a fully sealed and resin-potted stainless steel body, housing a tri-axial MEMS sensor, a balance wheel carriage, and a tubular extension element (in steel or carbon fiber). In-place inclinometers are installed inside inclinometer casing, arranged in continuous chains (connected by rigid rods and special joints) or discontinuous configurations (connected to the casing head via a suspension cable). Electrical connection is made either through a signal cable or, alternatively, via waterproof connectors. Each probe is equipped with wheel carriages that run inside the inclinometer casing guides, ensuring correct orientation and measurement repeatability. The continuous chain configuration enables automated monitoring along the entire measurement column, allowing reconstruction of the displacement profile over time and identification of potential critical zones along depth. Thanks to the availability of both analog outputs (0–5 V or 4–20 mA) and digital output (RS-485 with Modbus RTU protocol), the inclinometer can be easily integrated with data acquisition units and remote monitoring platforms. The modular configuration, with variable gage spacing, allows installation to be adapted to site-specific requirements, concentrating measurement points in the most critical zones. High long-term reliability and ease of installation make the GESTECNO inclinometer an effective solution for permanent monitoring and geotechnical and structural control applications.
