Abstract
An electrode (10) intended for measurement of relative permittivity. Each one of the electrically conductive electrode elements of the electrode (12) of an even number, e.g. n, there being electrodes includes a corresponding line wire (20 and 22, respectively) for connection to a measuring bridge or the like. The electrode elements (12) are mutually separated by means of spacer means (18) of electrically insulating material. The lead-in wires (20,22) of adjacent electrode elements (12) can be connected in pairs for measurement. The electrode elements (12) are arranged on an electrode body (14) shape like to a rod and of an electrically insulating material. The electrode elements (12) are tubular and are arranged in recesses (16) with adapted measures in the electrode body. The spacer means (18) comprise of annular members intergral with the electrode body (14).
