Inline sensor arrangement and method for commissioning same

A method for bringing an inline sensor arrangement into service for registering measured values of a measured variable representing an analyte content of a measured medium, the method comprising:

• providing an inline sensor arrangement including a sensor structured to produce and to output a measurement signal correlated with a measured variable representing an analyte content of a measured medium, wherein the sensor has at least one sterile sensor element configured to contact the measured medium and a housing that surrounds and encloses the sensor element in a chamber sealed from an environment of the housing;
• performing a heat sterilization of at least one part of the inline sensor arrangement including a housing exterior of the housing;
• irreversibly opening the housing to an interior of the container in a sterilized region of the housing exterior of the housing after terminating the heat sterilization;
• and
• bringing the sensor element into contact with the measured medium.
