Device for capacitively examining a measuring object, in particular a cylinder of a ceramical combustion tube.

摘要

A device for capacitively examining a measuring object (4) has two sensor pairs for completing an undersized diameter at all points of the lateral surface of the measuring object (4). Each sensor pair has two sensors (9) which are directly opposite one another in a straight line and are electric capacitors. The electric field of these capacitors reaches into a receiving channel (3) for the measuring object (4). The receiving channel (3) is arranged between the sensors (9) of each of the two sensor pairs. These sensor pairs are at an angular distance from one another in relation to the receiving channel (3).
