The Geosense Spiral Probe is used to measure the spiral in installed inclinometer casing. Within a vertical inclinometer installation there will be a combination of borehole spiral deformation (twist) which is a combination of the properties of the inclinometer casing during manufacture plus the quality of the installation. In deep installations (>50m) the affects of this can be significant and therefore it is important to understand the magnitude of any twist.
It can be used with any compatible vertical inclinometer system by using the same cable, reel, and hand-held readout. It is only necessary to read one data set; no 180 degree second reading set is required. Inclinometer Software processes the resulting spiral data set.
INCLINOMETER SPIRAL SENSOR
The MEMS Inclinometer Spiral Sensor is used to determine down-hole helical deformation of installed inclinometer casing. Installed casing spiral is a function of the manufacturing process, casing coupling, and installation technique.

Rated 0 out of 5
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.

Rated 0 out of 5
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
TILT BEAM MEMS

Rated 0 out of 5
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.

DRIVE-IN PIEZOMETERS WP-3400 & SGP-3500 SERIES
In stock
Rated 0 out of 5
Drive-in piezometers, also referred to as push-in piezometers, are designed for installing in soft clays, organic or fine grained cohesionless soils typically with a SPT-N value less than 10. They are available with a CPT fitting or 1” BSP thread.
Depending on the depth and type of soil, they can either be pushed directly into the soil from ground level to the required depth or pushed into the base of a CPT test or drilled borehole.
