Abstract

The invention relates to a sleeve (10), in particular a protective casing, for covering a sensor, in particular for covering a temperature sensor (70). According to the invention, the sleeve (10) is made from a nickel-chromium-aluminum-iron alloy wherein the alloy is made from 10.0 - 30.0 wt.% chromium (Cr), 0.5 - 5.0 wt.% aluminium (Al), 0.5 - 15.0 wt.% iron (Fe) and 50.0 - 89.0 wt. % nickel (Ni).

Description

technical field [0001] The invention relates to a bushing, in particular a protective cover, for covering a sensor, in particular a temperature sensor. The invention also relates to a temperature measuring device, in particular for a turbocharged internal combustion engine, comprising a sensor, in particular a temperature sensor, especially a platinum sensor. Furthermore, the invention also relates to a method for connecting a bushing, in particular a bushing according to the invention, with a temperature measuring device, in particular a temperature measuring device according to the invention. The invention also relates to the use of the alloy in the manufacture of sleeves for covering sensors. Background technique [0002] It is known to use a sleeve to cover the temperature sensor, ie the temperature sensor. Current bushings of this type are assembled from multiple bushings that are different in shape and welded into a single bushing. Furthermore, the sleeves disclosed...
