Patent ID: 8531653

Claim:
An apparatus for the analysis of a fluid in a line ( 13 ) or in a container, having an optoelectronic apparatus ( 14 ) for the optical analysis, comprising: at least two housing parts ( 16 , 18 ) having housing flanges ( 42 , 44 ) for flanging to a wall of the line ( 13 ) or of the container so that the housing parts are disposed opposite one another; a light transmitter ( 22 ) and a light receiver ( 24 ) which define an optical measurement path ( 33 ) between them within the line ( 13 ) or the container; and an evaluation unit ( 28 ), further having a temperature measurement apparatus ( 57 ) and/or a pressure measuring apparatus ( 59 ), wherein, for detecting the fluid temperature or fluid pressure in the region of the optical measurement path ( 33 ), the temperature measuring apparatus ( 57 ) is held extending parallel to the optical measurement path ( 33 ) within the line ( 13 ) or the container via a spacer ( 52 ) or a dynamic pressure pipe ( 54 ) of the pressure measuring apparatus ( 59 ) and the spacer ( 52 ) or the dynamic pressure pipe ( 54 ) is fastened to an intermediate flange ( 50 ) which can be inserted between one of the housing flanges ( 42 and 44 respectively) and the wall.
