Arrangement for the optical measurement of one or more physical, chemical and / or biological process variables of a medium

摘要

The invention relates to an arrangement (1) for the optical measurement of one or more physical, chemical and / or biological process variables of a medium (2), wherein the arrangement (1) comprises a housing (3) and the housing (3) for receiving a measuring device (4) is designed to determine the physical and / or chemical process variables, wherein in the housing (3) at least one window (5) is arranged and at least the window (5) is in contact with the medium, and wherein a vibration transmitter (6) for transmitting Sound wave is provided, characterized in that the window (5) is rigidly connected to the housing (3), the vibration transmitter (6) in a peripheral module (7) with a module housing (8) is arranged, the peripheral module (7) is arranged so that the vibration generator (6) sends the sound waves in the direction of the window (5), wherein the sound waves pass through the module housing (8) at a passage surface (9), and the peripheral module (7) so on ordered is that medium (2) is in the range of window (5) and passage surface (9).
