MAGNETIC EXTENSOMETER GXM RANGE
The GEO-XM settlement system is a magnet extensometer system used typically to monitor settlement and heave in foundations, excavations and embankments.
Data received identifies the depth and position where settlement has occurred as well as the total amount of settlement.
It can also be installed behind retaining structures, such as sheet piles and slurry walls, and above underground openings, such as tunnels and shafts.
Description
The system comprises a central access tube along which magnetic targets are positioned at various locations. Settlement is measured by the relative position of the magnetic targets using a Reed Switch Probe lowered down through the central access casing.
There are several variations to suit individual applications:
- GXM-100 Central access tubing and spider magnets for use in boreholes
- GXM-100P Central access tubing and settlement plates for use in fill
- GXM-100T Central access tubing with telescopic joints for larger movement
- GXM-200 Combined settlement/heave and inclination using inclinometer casing as the access tubing with spider magnets
- GXM-200P Combined settlement/heave and inclination using inclinometer casing as the access tubing with settlement plates
- GXM-200T Combined settlement/heave and inclination using inclinometer casing with telescopic joints for larger movement
- GXM-300 Central access tubing de-bonded by an outer corrugated pipe with magnetic targets
- GXM-300i Combined settlement/heave and inclination using inclinometer casing as the access tubing de-bonded by an outer corrugated pipe with magnetic targets

IPX IN-PLACE EXTENSOMETER
In stock
The In-Place Extensometer (IPX) offers automated monitoring of standard magnetic extensometer installations. The system is designed for a simple, adaptable installation with a single cable connection at the top of the borehole. Its large measurement range accommodates large levels of settlement or heave, and ease of adjustment means it can be reconfigured for changed site conditions such as embankment filling or cutting.
BOREHOLE ROD EXTENSOMETER
In stock
The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock.
It consists of a reference head and one or more in-hole anchors each of which is placed at a known depth and connected to the reference head by either a rigid or flexible rod running inside a flexible sleeve, which keeps the rod de-bonded from the grout.
NANO TRIAXIAL TILT SENSOR
In stock
The Nano range uses the same core platform as our other tilt sensors, so it can deliver a similar level of performance and reliability, all in a small and robust enclosure. Nanos have been successfully used in many applications, including:
- Tunnel distortion
- Tunnel heave/settlement
- Embankment slippage (used in conjunction with stake mounts)
- Structural movement
- Rail track heave/settlement
- Rail trackbed cant and twist

The structural infrastructure must always meet requirements such as performance, stability and durability. These requirements will have a lasting effect on our mobility in the future. The corrosion risk and the corrosion activity of the reinforcing steel largely define these requirements and are determined by various impact and material parameters.
