DIGITAL TAPE EXTENSOMETER
The Digital Tape Extensometer is a portable device used for measuring displacement between reference anchors fixed to an excavation or structure.
The instrument consists of a precision punched steel tape incorporating a repeatable tensioning system and dial gauge readout. The tape winds onto a reel, which incorporates a tape tensioning device and a digital LCD readout.
The body of the extensometer has a hook connector that connects to the first eyebolt. An identical hook on the free end of the tape connects to the opposing eye bolt. The user then tensions the instrument and records the readings from the digital LCD display. The measurements are not absolute, but relative to the previous measurement. This provides an accurate record of displacement over time.
These can be installed on a structure or in an excavation such as a tunnel or shaft.

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.

MAGNETIC EXTENSOMETER GXM RANGE
In stock
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.
