Automated Subsurface Displacement Monitoring
Installed continuously along a borehole, the RT-1010 automatically measures lateral displacement at different depths, reducing repeated manual inclinometer surveys. Optional components integrate groundwater level, water temperature and settlement monitoring at multiple depths in the same borehole, reducing the need for additional boreholes.
Applications & measurement profiles
Primarily designed for subsurface displacement,
with horizontal settlement and arched convergence applications.
Installed vertically inside borehole inclinometer casing, the array continuously measures lateral displacement at different depths. Comparing profiles over time helps identify depths where deformation is concentrated.
Installed in an arch along a structural cross-section, the array measures convergence at each point relative to one end. Comparing cross-sectional profiles from different dates reveals changes in the structure's shape.
Installed horizontally along a roadbed or dam, the array measures settlement at each position relative to one end. Profiles show the distribution of settlement along the monitoring line and how it changes over time.
Example profiles use different installation arrangements; they are not simultaneous outputs from one string. The animations follow the sampling dates.
Installation
The continuous flexible sensor string is installed along inclinometer casing and secured with fixing and protection components at the borehole opening. Connect it to an RT-1000 or RT-2000 data logger, or the project's existing data acquisition equipment, for automatic measurements.
A water-level sensor integrated at the bottom of the string measures groundwater level and water temperature together. Combine these readings with displacement data to assess the relationship between water-level changes and deformation.
Settlement monitoring components can be integrated into selected sections. Used with magnetic settlement rings, they measure settlement of soil layers at different depths.

Built-in temperature measurement enables automatic temperature compensation to reduce the effects of temperature changes on readings. Settlement and convergence monitoring also include automatic torsion correction.
A sealed waterproof structure with lightning and electrostatic protection is designed for submerged boreholes and long-term outdoor monitoring. Select the appropriate product version for the site's water pressure.
An RS485 interface supports standard Modbus, ASCII and a proprietary hexadecimal protocol for connection to data acquisition equipment and monitoring systems.
Product selection
Confirm the monitoring target and installation arrangement, then select the section length, precision version and integrated components. Finally, check water pressure, power and data acquisition requirements.

Selection & integration
Yes. The RT-1010 uses an RS485 interface and supports standard Modbus, ASCII and a proprietary hexadecimal protocol. Check power supply, protocol and channel configuration during equipment selection. RT-1000 and RT-2000 data loggers are also available.
The available functions depend on the installation arrangement and selected components. Vertical borehole installation primarily measures subsurface lateral displacement; groundwater level, water temperature and settlement at multiple depths require the corresponding components. Settlement profiling uses horizontal installation, while convergence uses arched installation. These applications do not all operate simultaneously by default on one sensor string.
Built-in temperature measurement supports automatic temperature compensation. Water temperature is measured by the optional combined groundwater-level and water-temperature sensor. Their purposes and measurement locations differ, so select the configuration for the actual monitoring requirements.
Displacement along the sensor string is calculated from section inclination and section length, relative to a selected reference point. Confirm the reference point and initial measurement state during installation, then compare subsequent deformation using the same reference.
