High temperature measuring sensor arrangement

A high-temperature measuring sensor arrangement comprising a sensor element located in a protecting tube with a measuring section exposed at an end of the protecting tube and oriented towards a hot side and opposite connections pointing towards a cold side, further with a protective cap connected to the protecting tube and enclosing the measuring section and a first stabilizing and fastening sleeve directed towards the hot side, wherein:

• the first stabilizing and fastening sleeve directed towards the hot side overlays the protective cap at the end thereof pointing towards the protective cap and provides stabilization against vibrational forces, wherein thermal expansions in a direction of a longitudinal axis are absorbed by a joining connection between the protective cap and the first stabilizing and fastening sleeve, and
• a second stabilizing and fastening sleeve directed towards the cold side is provided, which overlays the protecting tube at the connection-side end and supports the protecting tube, wherein the first and/or the second stabilizing and fastening sleeves are designed with a reduced diameter in a region of the joint and the overlay and, for a remainder of the first and/or second stabilizing and fastening sleeves, are designed with a distance to the protecting tube.
