Abstract
A sensor component for application temperatures above 700° C., especially electrical and/or electrochemical sensor component is provided. The sensor component has a feedthrough element, the feedthrough element having a through-hole with a through-hole inner wall extending from one surface of the feedthrough element to the other surface of the feedthrough element, wherein an insulation element is located within a through-hole of the feedthrough element, the through-hole has a diameter Da, the insulation element has a Volume V and a height H which are compact.
Claims13
A sensor component for application temperatures above 700° C., comprising:
- a feedthrough element made of metal, the feedthrough element having a through-hole with a through-hole inner wall;
- an insulation element in the through-hole of the feedthrough element, the insulation element being joined with the feedthrough element so that there is a physical and/or a chemical bond between the insulation element and the through-hole inner wall,
- wherein the feedthrough element has a first outer diameter (D),
- wherein the insulation element has a second outer diameter (Da), a volume (V), and a height (H),
- wherein the through-hole has a diameter (Dh) that corresponds to the second outer diameter (Da),
- wherein the first outer diameter (D), the diameter (Dh), the second outer diameter (Da), the volume (V), and the height (H) have dimensions selected from a group consisting of:
- the height (H) from 2 to 20 mm, the first outer diameter (D) from 2 to 30 mm, a ratio of V/D from 0.2 to 100, a ratio of V/D from 1 to 50, a ratio of V/D from 2 to 20, a ratio H/D from 0.15 to 1.2, a ratio H/D from 0.2 to 1.0, a ratio H/D from 0.4 to 0.8, and any combinations thereof, and
- wherein an extension portion of the insulation element has an outer diameter that is less than the through-hole diameter (Dh) of the feedthrough element so that a gap is formed between the inner wall of the through-hole and the extension portion of the insulation element.
