摘要:
A concentration measuring device for determining a concentration of gas or particles in a measurement volume includes at least one housing having an opening for communication with the measurement volume, a light source for transmitting measurement light through the housing into the measurement volume, a light receiver for receiving the measurement light after its passage through the measurement volume and an evaluation unit which is designed for determining the concentration of gas or particles from the measurement light received at the light receiver. In accordance with the invention at least one body of solid material is arranged in the at least one housing such that the measurement light path largely passes through the at least one solid body within the housing, with the portion of the measurement light path within the at least one housing not passing through the at least one solid body having a specified total length.

The invention relates to an apparatus for the analysis of a fluid which is present in a line or in a container. It can e.g. be a gas flow in a gas line. The apparatus has an optoelectronic apparatus for the optical analysis. The optoelectronic apparatus itself includes at least two housing parts having housing flanges for flanging the apparatus to a wall of the line or of the container so that the housing parts are disposed opposite one another, a light transmitter and a light receiver which define an optical measurement path between them within the line or the container and an evaluation device. A temperature sensor for detecting the fluid temperature and/or a pressure sensor for detecting the fluid pressure is/are provided beside the optoelectronic apparatus. To provide an improved apparatus for the analysis of a fluid with which temperature and/or pressure can be detected in a simple and in particular inexpensive manner, it is proposed that, 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.

An optical analyzer, in particular an optical gas analyzer, having a holder (10) for installing into a gas-carrying hollow space, wherein the holder (10) has a ball socket (20) and a ball segment (30) with a longitudinal axis (A), wherein the ball socket (20) has at least one first segment (21) and a second segment (22) and is designed such that it at least partly engages around the ball segment (30) in the direction of the longitudinal axis (A).
摘要:
The invention relates to an optical analysis device for analyzing a medium in a measurement volume, comprising a housing having an opening, a flange for holding the housing in a reception opening of the measurement volume and an optical analysis unit in the housing. In accordance with the invention, a fastening stub provided at the housing and including the opening is provided for fastening the housing in the flange, with the fastening stub having an outer geometry which is matched to the inner geometry of the flange such that it can be displaced in the flange in the direction of the measurement volume and away from it. A clip is provided with which the flange and the fastening stub can be connected to one another in shape-matched and/or force-transmitting manner in different positions of the fastening stub in the flange.
