Inclination – Tilting

What is an inclinometer used for? How to choose the right instrument depending on the measurement environment and the type of structure to be monitored (tilted walls, structural deformation, balconies, etc.)?

What is an inclinometer?

An inclinometer is a measuring tool used to monitor changes in the inclination of a structure. In the building industry, this device allows you to track shifts in the tilt or inclination of a wall or balcony.

How does an inclinometer work?

The inclinometer operates on a relatively simple principle based on a pendulum. The device is mounted either flat or perpendicular to the surface, depending on the configuration. Thanks to gravity, the needle indicates the inclination angle.

To take a reading, the user must face the inclinometer with their eyes level with the dial. The reading is then taken by first identifying the lower division, which provides the measurement scale, and then reading the upper division indicated by the swinging needle.

How to choose the right inclinometer?

For monitoring a risky wall or balcony, two main criteria guide the selection of an inclinometer:

• Measurement resolution: 0.03° for G5 or G5+ models, or 0.06° for the G5mini model

• The need to avoid leaving the device in place to prevent damage: in this case, a removable inclinometer is necessary.
  The key factor is the repeatability of the measurement. Each new reading must be taken under the same conditions as the previous one. Otherwise, the data won’t be reliable. The removable G5+ inclinometer uses precisely machined parts to ensure consistent positioning every time.

How to choose an inclinometer based on the measurement environment?

Size constraints may also influence your choice. For minimal space requirements, we developed the G5 gauge in a mini version. Its compact dimensions offer optimal discretion: only 170 mm x 70 mm x 18 mm.

Environmental conditions should also be considered. Is the measurement taken indoors or outdoors? Under what weather conditions? G5 gauges are designed to withstand the elements, but for added durability and in harsh conditions, you can:

• Add protective covers to the G5 gauge

• Use a removable G5+ gauge: only the aluminum baseplate remains outdoors

How to find a simple and user-friendly inclinometer?

At Saugnac Jauges, the G5 range of inclinometers operates using a vernier principle, which is very easy to read and offers 0.1 mm precision (equivalent to 0.03° or 0.06°, depending on the model).

In addition, a free app is provided to help you collect and secure your data and photos.

Can an inclinometer be used to measure the tilting of a retaining wall?

Absolutely. One or several inclinometers can be used to monitor the tilt of a retaining wall. For example, the removable G5+ inclinometer combined with several mounting bases positioned at different points allows for accurate monitoring.

We also offer a custom G130 solution that tracks wall tilting using a cable fixed at two endpoints across the wall and multiple G3-type gauges installed along its length.
