MS-DS10-IPX-In-Place Extensometer
The In-Place Extensometer (IPX) automates new or existing magnetic extensometer installations to provide high precision vertical displacement measurements in near-real time.
The IPX has been designed to enhance the many benefits of traditional magnetic extensometers such as offering a high capacity for number of measurement points in a single borehole, a large measurement range, and the flexibility to adapt the system with construction activities such as embankment raises or excavation.
Product Features
- Low profile – can be installed in standard 33mm magnetic extensometer access tube
- High density – up to 40 instruments per borehole
- Single cable bus system allows easy, low-cost data logging and telemetry options
- Top or bottom supported installation to suit your application
- Low power – no external power supply or solar panels
- Compatible and retrofittable with most existing magnetic extensometers1
- Designed specifically for ease of extension with fill raises or shortening with excavation
- Output in engineering units – no data conversion necessary
- Consolidation of soil and fill during embankment construction
- Heave during and post excavation
- Subsidence of tunnels or mines
- Tunnel convergence
- Slope stability – cuttings, embankments or natural slopes
- Lateral displacement beneath an embankment or in a slope
Applications
Field connections made easy – the in-line submersible connector allows you to quickly connect and disconnect data loggers or additional instruments.
Top SupportCan be used to suspend the string from the top of the casing in top supported installations. Includes an M12 socket for secure fitting of survey markers or prisms.
GRP Support RodHigh-quality plastic-coated GRP rod – 6mm OD – comes with stand and reel with braking mechanism for safe and efficient installation. Refill lengths also available.
Magnetic Target(Supplied by others) The IPX is compatible with most standard magnetic targets. Magnetic targets are grouted within the borehole and move with the surrounding ground independently of the access tube.
Access Tube(Supplied by others) The IPX is compatible with standard 1” (25.4mm) ID access tube provided care is taken to ensure a straight installation. Osprey recommends the use of 35mm ID access tube where lateral deformation is likely.
Bottom SupportProtects GRP support rod during installation and throughout operational life. High quality stainless steel with two 2mm set screws for securing to the rod.
In-Place ExtensometerHigh precision digital magnet displacement sensor, 20mm OD, Digital Serial BUS, 2mm set screws for mounting on 6mm GRP Rod.
