Abstract

The present disclosure relates to an inline sensor arrangement for the detection of measurement values of a measurand representing an analyte content of a measuring medium, which arrangement comprises: a sensor which is designed to generate and output a measurement signal correlated with the measurand, wherein the sensor has at least one sterile sensor element provided for contact with the measurement medium; and a housing surrounding the at least one sensor element, which housing encloses the sensor element in a chamber sealed tightly against an environment of the housing, and wherein the chamber contains inside it a gas volume that is designed such that an influence of harmful substances—in particular, of reactive nitrogen and/or oxygen species—on the at least one sensor element is largely prevented. The present disclosure further relates to a method for the production of said inline sensor arrangement, and for its commissioning.
