EXTENSOMETER GEO-XW100
The GEO-XW100 Rotary Wire Extensometer is designed to monitor the changes in distance between two anchor points up to a maximum of 30 meters apart.
It comprises a rotary potentiometric displacement gauge, an opposing anchor and a stainless steel wire that runs between the displacement gauge and the opposing anchor. With a wire extension kit, the length of the wire can be extended up to a maximum distance of 30 meters.
The displacement gauge is housed within a rugged steel enclosure with a mounting plate for horizontal or vertical mounting.
Two options for installation are available as follows:
- Exposed wire in combination with expansion anchor and eyebolt typically for attaching to rock or concrete.
- Wire running within a protective sleeve where the bottom anchor is mounted in the bottom cap at the end of the protective sleeve. The protective sleeves can either be mounted on posts above ground or buried typically used for slope and/or landslide monitoring.

PORTABLE MEMS INCLINOMETER
In stock
The MEMS Portable Inclinometer system utilises modern communication and Smart devices to enable the tilt data generated by the probe to be managed, stored and transferred directly from site via FTP, API, email or other communication platforms.
It is available for vertical, inclined and horizontal applications.
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.

HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
