ABSTRACT:
An immersion tube for a measuring probe of a type where a sensor element is arranged at the end of the measuring probe has a sleeve and an end piece. The end piece includes a plug, a connector piece, and a protector basket arranged between the plug and the connector piece. The connector piece connects the end piece to the sleeve and has an internal diameter that is enlarged relative to the internal diameter of the protector basket. The enlarged internal diameter portion ends at a circular internal step that can be seat for a sealing means, can provide a circular sealing lip, or both. A breakthrough opening on the protector basket is arranged perpendicular to the longitudinal axis of the immersion tube, whereby the sensor element which in operation is located in the protector basket can be brought into direct contact with a measurement medium. All surfaces and edges of the immersion tube which are exposed to the measurement medium during operation are smooth and rounded.
