Inclinometer is an instrument for measuring angles of slope and inclination of an object with respect to its gravity by creating an artificial horizon. It is also known as a tilt sensor, tilt indicator, slope meter, slope gauge, gradient meter, gradiometer, angle indicator, bubble level, clinometer, digital protractor, level gauge & level meter. Inclinometer is commonly used in different industries like Aviation, civil engineering, Government, Marine, Military, and Transportation for platform leveling, boom angle indication and slope angle measurement.

The tilt angle range is the range of desired linear output measured in degrees. Important specifications to consider when searching for tilt sensors and inclinometers are the tilt angle range and number of axes. There are two types of inclinometers: vertical inclinometers and horizontal inclinometers.

Applications of Inclinometers

  • Measurement of angles of elevation, slope, or incline, of an object.
  • Measurement of slight differences in slopes, particularly for geophysics. Such inclinometers are, for instance, used for monitoring volcanoes, or for measuring the depth and rate of landslide movement.
  • Determining the angle of the Earth’s magnetic field with respect to the horizontal plane.
  • Measurement of angular deviation from the true vertical or horizontal.
  • In Surveying, to measure an angle of inclination or elevation.
  • Alerting an equipment operator that it may tip over.
  • Measuring movements in walls or the ground in civil engineering projects.
  • Determining the dip of beds or strata, or the slope of an embankment or cutting; a kind of plumb level.
  • Measurement of angular position of vehicle components in automotive safety systems.
  • Indicating pitch and roll of vehicles, nautical craft, and aircraft. See turn coordinator and slip indicator.
  • Monitoring the boom angle of cranes and material handlers.
  • Measuring the “look angle” of a satellite antenna towards a satellite.
  • Adjusting a solar panel to the optimal angle to maximize its output.
  • Measuring the slope angle of a tape or chain during distance measurement.
  • Measuring the height of a building, tree, or other feature using a vertical angle and a distance (determined by taping or pacing), using trigonometry.
  • Measuring the angle of drilling in well logging.
  • Measuring the list of a ship in still water and the roll in rough water.
  • Measurement of steepness of a ski slope.
  • Measuring the orientation of planes and lineations in rocks, in combination with a compass, in structural geology.
  • Measuring Range of Motion in the joints of the body
  • Measuring the inclination angle of the pelvis.
  • Measuring the angles of elevation to, and ultimately computing the altitudes of, many things otherwise inaccessible for direct measurement.
  • Platform Leveling, Boom Angle Indication, Pitch & Roll, Grade or Slope Angle, Rollover/Tip Over Warning, Ball Banking Curves, etc.

Liquid Capacitive Inclinometer

Liquid capacitive inclinometers are Inclinometers whose sensing elements are made with liquid capacitive technology. Liquid capacitive inclinometers are considered gravity based. The best way to understand how they work is to think of a disc-like cavity that is half filled with a dielectric liquid.
