An inclinometers, also known as a tilt sensor or tilt meter, is an instrument used to measure the angle of inclination or tilt of an object relative to a reference plane, typically the horizontal or vertical plane. It is commonly used in various fields, including civil engineering, geotechnics, and construction, to monitor the stability of structures, slopes, and foundations. The device can provide real-time data, helping engineers assess potential risks related to ground movement or structural integrity. Inclinometers can be mechanical, electronic, or digital, depending on the application and required precision.
