Military instruments as a class draw on most of the categories of instrument described throughout this article, such as navigation, astronomy, optics, and imaging, and the kinetics of moving objects. Common abstract themes that unite military instruments are seeing into the distance, seeing in the dark, knowing an object's geographic location ...
An astronomical instrument is a device for observing, measuring, or recording astronomical data. [ citation needed ] They are used in the scientific field of astronomy , a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator , tilt sensor , tilt meter , slope alert , slope gauge , gradient meter , gradiometer , level gauge , level meter , declinometer , and pitch & roll ...

An inclinometer or clinometer essentially mean the same thing: that being an instrument to measure tilt angle in reference to gravity. However, each term does have specific meanings to specific industries.
Liquid capacitive inclinometers are inclinometers (or clinometers) whose sensing elements are made with a liquid-filled differential capacitor; they sense the local direction of acceleration due to gravity (or movement). [1] A capacitive inclinometer has a disc-like cavity that is partly filled with a dielectric liquid.
However, if they are mounted on a suitable scale the instrument may also be used as an inclinometer to measure angles to the vertical. Ancient Egyptians used a plumb line attached to the top outer part of a tool resembling a letter E ; when placed against a wall, the plumb line would indicate a vertical line.
