Apparatus for remotely indicating angular position.

摘要

A sensor (16) is affixed to a piece of rotatable equipment (10). The sensor has a rolling member (26) freely moveable within a cage member (18). In operation, the rolling member (26) contacts electrically conductive surfaces (28, 30) disposed about the interior of the cage member. By determining which particular pair of surfaces are currently in contact with the rolling member, the orientation of the cage member with respect to the horizontal is known. The preferred embodiment utilizes a resistor network (34) and an electrical measuring device (48) for making this determination.
