An arrangement of probes is described, which comprises a carrier formed as an intermediate flange, in which a plurality of radially extending mounting openings are provided. The inner surfaces of the carrier are provided with an electrically insulating corrosion resistant layer, which is preferably an enamel layer. The carrier is having a polygonal outline and plane mounting surfaces surrounding the mounting openings. Measuring probes provided with a mounting flange can be exchangeably and sealingly attached to the mounting surfaces. By arranging different probes a large number of different measurement functions and supervision functions can be achieved. As an example, carrier sleeves comprising a window can be built in, so that a visual observation or a turbidity measurement can be performed.

Arrangement of probes

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 walled bottom region is provided with a coating out of silver.

Temperature measuring sensor arrangement

An enamelled or glass coated measuring probe is described, comprising a carrier an electrode fused into an enamelled probe body. The carrier is shaped as a cone out of enamel or ceramic material, into which the electrode or cylindrical metallic body serving for mounting the electrode is fused. In accordance with one embodiment one or several electrodes can be fused into the cone, while in another embodiment the electrode may be exchanged by an electrode out of a different material.
