Sensor, in particular capacitive sensor for aircraft tank

Abstract

Sensor, in particular capacitive sensor for aircraft tank The invention relates to a sensor (1) suitable for measuring the dielectric permittivity of a medium, in particular a fuel in a tank, comprising: a support (3), insulating fixing elements (17), a plurality of plates (7) comprising at least a first plate (7a) and a second plate (7b) parallel and aligned along a stacking axis (X), at least a first support column (11) connecting the first plate (7a) to one of the insulating fixing elements (17), at least a second support column (13) connecting the second plate (7b) to one of the insulating fixing elements (17), at least one additional plate (7c), and at least one spacing column (15) connecting the additional plate to a plate which is the second nearest neighbor.The support (3) and the plates (7) are made of the same first metallic material, and the spacer column (15) is made of a second metallic material. Figure to be published with the abbreviation: Figure 3.

Claims

of glass.

4. A sensor (1) according to any preceding claim, wherein the first support column (11) is made of a third metallic material and / or the second support column (13) is made of a fourth metallic material.

5. Sensor (1) according to the preceding claim, wherein the plurality of plates (7) comprises an even number of plates (7).

6. Sensor (1) according to the preceding claim, in which the second metallic material and the third metallic material, and in particular the fourth metallic material, are identical.
