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.
Description
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.

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

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.
