Liquid Capacitive Inclinometers

Liquid capacitive inclinometers are Inclinometers (or Clinometers) whose sensing elements are made with liquid capacitive technology; they 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. One of the sides of the cavity has an etched conductor plate that is used to form one of the conductors of a variable parallel plate capacitor. The liquid along with the other side of the cavity forms the other plate of the capacitor. In operation, the sensor is mounted so that the disc is positioned perpendicular to the ground (vertically mounted). Gravity then acts on the liquid pulling it down in the cavity forming a semicircle. As the sensor is rotated the liquid remains in this semicircular pattern covering a different area of the etched plate. This change in area results in a change in the capacitance. The change in capacitance is then electronically converted into an output signal that is linear with respect to the input angle.

An inclinometer or clinometer is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, and pitch & roll indicator.

More particularly, an inclinometer can refer to:

  • An instrument used to determine the angle of the Earth's magnetic field in respect to the horizontal plane.
  • An instrument for showing the inclination of an aircraft or ship relative to the horizontal. An airplane instrument. See turn coordinator or slip indicator.
  • An instrument for showing a deviation from the true vertical or horizontal
  • An instrument used by surveyors in order to measure an angle of inclination or elevation
  • Compass with inclinometer
  • An inclinometer is used as a rollover warning, to alert equipment operator of possible tip over condition.
  • Any of various surveying instruments for measuring angles of elevation, slope, or incline, as of an embankment. Also called a clinometer.
  • An instrument for measuring 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.
  • An inclinometer may also be used in civil engineering projects to measure movements in walls and/or the ground.
  • An instrument for determining the dip of beds or strata, or the slope of an embankment or cutting; a kind of plumb level.
  • An instrument used by surveyors in order to measure an angle of inclination or elevation
  • An inclinometer may also be used in some automotive safety systems.

Tilt sensors and inclinometers generate an artificial horizon and measure angular tilt with respect to this horizon. They are used in cameras, aircraft flight controls, automobile security systems, and special switches. Also used for platform leveling, boom angle indication, anywhere tilt requires measuring. Important specifications to consider when searching for tilt sensors and inclinometers are the tilt angle range and number of axes. The tilt angle range is the range of desired linear output measured in degrees. The number of axes the inclinometer and tilt sensor measure on is another important specification.

Tilt sensor technology has also been implemented in video games. Yoshi's Universal Gravitation and Kirby Tilt 'n' Tumble are both built around a tilt sensor mechanism, which is built into the cartridge. The new PlayStation 3 game controller also utilizes tilt as a means to play video games.
