Publication number: 20130029374Abstract: A method, and a measuring point for performing the method, for measuring at least one physical and/or chemical, process variable of a medium contained in a single use container. A single use sensor is connected with the single use container. The single use sensor with the single use container is sterilized by radiation, especially beta or gamma radiation. An electronics unit is connected with the single use sensor, and the electronics unit is connected with at least one superordinated system via at least one interface. The electronics unit and/or the single use sensor are/is supplied with energy, and measurement data of the single use sensor are registered. The measurement data are processed by the electronics unit and/or the superordinated system, data, including measurement data, are transmitted to the superordinated system and/or received from the superordinated system, and, after termination of one or more measuring cycles, the electronics unit is released from the single use sensor.Type: ApplicationFiled: July 24, 2012Publication date: January 31, 2013Applicant: Endress + Hauser Conducta Gesellschaft für Mess- und Regeltechnik mbH + Co.
