Abstract: A device is provided for measuring parameters or for taking samples in molten iron or steel and for taking samples of slag resting on the melt. The device includes a carrier tube having an immersion end, a lateral circumferential surface, and a measuring head arranged on the immersion end. At least one sensor or inlet opening for a sample chamber present inside the device is arranged at the immersion end of the measuring head. The lateral circumferential surface of the carrier tube or measuring head has an inlet opening extending through an inlet channel to merge in a pre-chamber arranged inside the carrier tube or measuring head. The pre-chamber has, at its end facing away from the immersion end, an entry opening that merges into a slag sample chamber on the side of the pre-chamber facing away from the immersion end.

Abstract: A measuring probe for sampling melted metals, in particular melted steel, includes a measuring head arranged on an immersion end of a support tube. The measuring head includes at least one sample chamber. The sample chamber includes a feed channel having one end which opens into the sample chamber and a second end with a feed opening that projects from the front face of the measuring head facing away from the support tube and is covered by a protective cap. A protective shield is arranged outside of the feed channel upstream of the feed opening in a feed direction at a distance from the feed opening. The protective shield covers the feed opening and the protective shield does not fully surround the feed channel laterally.
