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.
Categories: Geo-Structural Instruments, Inclinometers
Description
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.

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

The structural infrastructure must always meet requirements such as performance, stability and durability. These requirements will have a lasting effect on our mobility in the future. The corrosion risk and the corrosion activity of the reinforcing steel largely define these requirements and are determined by various impact and material parameters.
