Abstract

A temperature measuring sensor arrangement is described, which can be inserted into or removed from an enamelled built in part in a simple manner without a need for specific tools. A measuring insert with a carrier is provided, along the length of which an outwardly protruding detent element in the form of a collar is provided, and from the lower end surface of which carrier one or several measuring sensors are protruding. The carrier is slidably arranged in a longitudinal direction in a guiding tube and is biased downwardly by a spring engaging between the detent element and a shoulder in the guiding tube. A stop protruding from the inner wall of the guiding tube limits the displacement of the biased carrier. The guiding tube is fixedly mounted at the upper end protruding from the guilt in part by means of a wedge ring-screwed joint in the inserted position, in which the detent element is raised from the stop and the ends of the measuring sensors are pressed against a surface formed at the enamelled built in part over a thin walled bottom region. The bottom region is provided with an upwardly extending conical enlargement for the insert end of the guiding tube. Preferably the thin…
