ABSTRACT:
An inclinometer includes two coplanar electrodes positioned within a chamber of a metallic housing containing a high relative dielectric constant fluid and a gas. With the inclinometer positioned on a level surface equal areas of the two electrodes are immersed in the dielectric fluid creating two equal capacitors formed by the electrodes and the metallic housing. When the inclinometer is rotated through an inclination angle, unequal areas of the electrodes are immersed in the fluid causing a capacitance differential that is a measure of the inclination angle.
