Sensors for measuring the spatial position of wells

Abstract

Gravity sensors used in inclinometers can be divided into two groups. The first group includes sensors that provide information about the direction of the gravity vector. These include various types of physical pendulum, float structures, where a float with a displaced center of gravity is located in liquid or in some other suspension (for example, magnetic, and prostatic, etc.); sensors with a solid ball on a concave surface and an air bubble under a spherical concave surface filled with liquid; sensors that use the horizontal property of the liquid level. The second group of sensors reacts to the magnitude of acceleration, in particular, the acceleration of gravity.
