Embodiment Construction
[0043] figure 1 A schematic sectional view shows a measuring device 1 produced according to the invention of a gas sensor connected to a measuring gas container 16 surrounding a measuring space 4 . follow in figure 1 In the embodiment shown in FIG. 1 , the measuring device 1 has a housing 9 which at least partially surrounds it and which has a receptacle 15 for a measuring gas container 16 . In this receptacle 15 , the sample gas container 16 , which is preferably a disposable component, can be fixed without tools in such a way that it is secure and relative to the measuring device 1 when adjusted for operation. to decorate. During operation, a gas flow with the gas to be measured, for example a breathing gas flow, flows through the measurement gas container 16 and encloses the measurement space 4 on the inside.
[0044] The measurement space 4 of the measurement gas container 16 is delimited on both sides by windows 17 , 18 , through which the radiation required for the me...

The invention relates to a measuring device for determining a module structure with a property of a gas to be measured and to a method for producing the measuring device. The measuring device has an electronic module having a radiation source for emitting radiation and a detector unit for at least partially receiving the emitted radiation after the radiation has passed through a measuring space; the measuring device has a housing which is connected to an optical unit for at least partially shaping and / or guiding the radiation emitted by the radiation source. The described technical solution is characterized in that the optical unit has at least one reflector which is produced as an off-axis reflector with respect to the main beam axis of the radiation, and the electronic module and / or the housing has at least one fastening means which is designed such that the electronic module and the housing can be connected to each other without tools in a position in which the electronic module and the housing are aligned and operable.
Description
technical field [0001] The invention relates to a modular measuring device for determining properties of a gas to be measured. The measuring device has an electronics module with a radiation source for emitting radiation and a detector unit for at least partially receiving the emitted radiation after it has penetrated the measurement space. Furthermore, a housing is provided which at least partially surrounds the measuring device and which is connected to an optical unit for at least partially shaping and / or shaping of the radiation emitted by the radiation source or boot. Background technique [0002] Various gas sensors are known from the prior art for ascertaining at least one property of the gas to be measured, which use optical measuring methods. Such a gas sensor has a suitably designed optical unit for guiding and shaping the radiation in the direction of and through the measurement volume in which the gas to be measured is located. After traversing the measurement...
