Device for measuring parameters or for taking samples in molten iron or steel

A device for measuring parameters or for taking samples in molten iron or molten steel and for taking samples of slag resting on the molten iron or molten steel, the device comprising:

• a carrier tube having an immersion end and a lateral circumferential surface, the immersion end of the carrier tube having arranged thereon a measuring head having an immersion end and a lateral circumferential surface, the lateral circumferential surface of the carrier tube or of the measuring head having a lateral inlet opening arranged thereon and extending through an inlet channel to merge in a pre-chamber arranged inside the carrier tube or inside the measuring head;
• and
• a splash guard layer made of metal and arranged on the exterior of the lateral circumferential surface of the carrier tube or the lateral circumferential surface of the measuring head so as to surround the lateral inlet opening without covering the lateral inlet opening,
• wherein at least one sensor or one front inlet opening for a sample chamber present inside the device is arranged at the immersion end of the measuring head, and
• wherein the pre-chamber comprises, at its end facing away from the immersion end of the measuring head, an entry opening that merges into a slag sample chamber arranged inside the device on a side of the pre-chamber facing away from the immersion end of the measuring head.
