IPX IN-PLACE EXTENSOMETER
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.
- Compatible
The IPX can be installed in most standard magnetic extensometer installations. It is compatible with most leading digital geotechnical data loggers and its low power consumption allows over 50 sensors to be connected to a single battery powered logger.
- Adaptable
Easily raised through fill or reduced with cutting – the IPX’s distinct bottom-supported configuration allows easy extension or reduction without interfering with the existing sensors.
- Adjustable
A unique coiled cable system allows adjustment of the sensor spacing according to site conditions. The cable’s coiled section allows 500mm of adjustment to the sensor’s position within the borehole.

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
PORTABLE MEMS INCLINOMETER

TILT BEAM MEMS
In stock
MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
