The Vertical Digital Inclinometer System is used to measure lateral deflections within a borehole. The system comprises a biaxial probe, cable reel and ultra-rugged Field Tablet supplied with ‘In-Port Pro’ data capture software.
The probe incorporates MEMS technology allowing highly accurate and repeatable readings, transferred via a digital signal. Bluetooth communication enables a cable free data transmitting system with no connectors to corrode or break.
The robust reinforced Kevlar® cable consists of a non slip cable marker system which, when used in conjunction with the cable gate, provides highly accurate and repeatable depth control.
With all these combined features, the Vertical Digital Inclinometer Pro System is a robust and highly accurate system that is light, compact and easy to operate in any site environment.

The inclinometer probe is inserted into the inclinometer casing and lowered to depth, ensuring the probe wheels are correctly aligned and slotted within the keyways of the casing. The probe is connected by a graduated cable to the cable reel.
Displacement readings are taken at regular intervals of 0.5m (2ft for imperial systems) within the casing (the gauge length between the probe wheels). This is measured and controlled by stainless steel markers crimped around the cable, these pass through a notch in the cable gate, giving an exact position for each reading.
By pressing the screen button or using auto run mode you can save readings from the MEMS sensors, which are transmitted to the Field Tablet from the cable reel via Bluetooth transmission.
An initial or ‘base’ set of inclinometer readings are obtained at each increment within the casing. The summation of each incremental reading provides a profile of horizontal displacement of the casing as a function of depth.
When you take all subsequent readings at identical depths the comparison of successive casing profiles indicates the depth, direction, magnitude and the rate of change of movement.
You can see the clearest indication of movement by plotting the change in displacement of the casing against depth using ‘In-Profile’ Inclinometer Data Management Package.
Digital Inclinometer systems are used to measure lateral displacement in the ground or structure. They are useful for determining the depth, direction, magnitude and rate of movement.
Typical applications include:
- Slope failures and landslides
- Shear and slip zones
- Diaphragm or sheet pile walls
- Monitoring bending in piles
- Verifying design assumptions and finite element analysis
- Retaining walls
