The invention relates to a capacitive detector and device for measuring the detector integral, including: a ribbon in a dielectric material (2), first and second electrodes (4, 5) shaped like combs and formed on a first surface of said ribbon, and a third electrode formed on the other surface of said ribbon and facing said first and second electrodes; the thickness (e) of the dielectric ribbon (2) is less than or equal to said predetermined period (?) divided by four times pi, or ?/4p=e; and the relationship resulting from division, in the numerator, of the capacity (C) between two adjacent branches (9, 11) of said first and second electrodes in the presence of at least one fluid having dielectric permittivity (ef) and, in the denominator, by the dielectric permittivity (ef) of the fluid multiplied by the capacity (Co) between the two adjacent branches of the first and second electrodes in the presence of the void is greater than or equal to one, or C/ef.Co= l. The invention further relates to a method for manufacturing a detector respecting the above conditions. |
