Settlement Monitoring
Settlement Monitoring with Depth
an automated settlement monitoring system designed to provide precise measurements of vertical displacement at depth.
Engineered for accuracy and flexibility, the IPX can be installed in standard boreholes and retrofitted where needed, allowing multiple sensors in a single installation.
Ideal for construction, excavation, and consolidation projects, it delivers reliable, high-resolution data while reducing the need for manual readings and site visits.
Features
Settlement Monitoring with Depth
Simple and smart automation of magnetic extensometers. Easy to install, adjust and retrieve, the IPX offers complete flexibility in settlement monitoring.
Low Power
Osprey Measurement Systems’ advanced protocol allows us to carry out sophisticated measurements and data processing without compromising battery life. Our low power design offers compatibility with battery operated data loggers without the need for an external power supply.
Easily Modify Sensor Positions
Our patented mounting system and coiled cable allows the installer to easily adjust the position of the IPX up or down the rod, without impacting the position of those above or below it. This can be useful where the stratum or a magnet is not at the expected depth.
User Defined Digital Commands
The digital output means only one signal cable is required to read an entire string of In-Place Extensometers. We offer a selection of RS-485 command lists, giving you the flexibility to link your system to a wide variety of data acquisition and telemetry devices.
Move With Your Project
Inevitably, extensometers are needed where ground level is either raised or lowered and the In-Place Extensometer is designed for adaptation. Thanks to our unique mounting and support design, extending or shortening an installation is made easy without compromising the other sensors.
How it works
The IPX is installed within standard magnetic extensometer installations, including standard 42mm access tube and 70mm inclinometer casing.
Sensors are positioned inside the access tube to align with the installed spider or plate magnets, held in position by a fiber reinforced rod. The sensor characterises the magnetic field created by the spider magnets and reports its position along the probe in millimetres.
Specially designed cable provides flexibility in positioning the sensors when on site. The sensors are easily relocated along the FRP rod using grub screws to secure the sensor in place.
The sensors communicate over an RS-485 serial bus allowing easy data retrieval by most geotechnical data logging devices.
The output precisely tells you the position of the magnetic target, so no data conversion is necessary.
