High temperature measuring sensor arrangement for e.g. motor car, has contoured portion that is extended over protective cap to take stabilization against oscillation force and receive thermally induced expansions in longitudinal axis

摘要

The sensor arrangement has a sensor element provided in a protective tube (1) exposed to hot side oriented measuring bead (2) and opposite to cold side lead wires (3). The measuring bead is connected to a protective cap (4) and an outer stabilization and fastening sleeve (5). A contoured portion (7) is extended over the cap such that the stabilization takes place along longitudinal axis against the oscillation forces, and joint between the contoured portion and stabilization and fastening sleeve receives thermally induced expansions along longitudinal direction.
