What is an Inclinometer? An inclinometer, sometimes called a tilt sensor, is a device that measures the angle of slope or inclination relative to gravity. It is used when engineers, builders or technicians need to know how much a structure, surface or machine is tilting. Modern inclinometers are compact, accurate, and based on MEMS (Micro-Electro-Mechanical Systems) technology, making them easy to integrate into field equipment. How it works The principle is simple: gravity acts on the sensing element inside the device. This displacement is converted into an electrical signal, which is then processed to calculate the angle of tilt. Depending on the design, inclinometers can measure one or two axes. They provide a direct reading of tilt angle, usually in degrees or radians, and are valued for their precision and robustness even in demanding environments. Where inclinometers are used In construction and civil engineering, inclinometers help monitor the stability of buildings, bridges and tunnels. They are used during excavation or demolition to track slope angles and avoid structural damage. On geotechnical sites, they detect ground movement, monitor dams and embankments, and give early warning of landslides. A concrete example is the monitoring of slender structures, where inclinometers play a crucial role in ensuring stability. Inclinometer vs accelerometer Although related, these two sensors have different roles. An accelerometer measures acceleration and vibrations, while an inclinometer measures tilt relative to gravity. Some advanced devices combine both technologies, offering a complete solution for monitoring vibration and tilt in real time. Discover more about our industrial accelerometers for vibration analysis. Choosing the right inclinometer The best inclinometer depends on the level of accuracy required, the number of axes to be measured, the measurement range (°), the environmental conditions, and the way data will be collected. For field work, robustness and easy installation are often essential. For laboratory or long-term monitoring, high resolution and integration with cloud platforms can make the difference.
