Claims (10)
einem einends einer durch ein Gehäuse (10, 26) be grenzten optischen Absorptionsstrecke vorgesehenen Strahlungserzeuger (16) und einem gegenüberliegend endseitig der Absorptionsstrecke vorgesehenen Strah lungssensor (20), dem eine Verstärker- und/oder De tektorelektronik (28) nachgeschaltet ist,
wobei dem Gehäuse Mittel (12) zum Einleiten von zu messendem Gas (14) zugeordnet sind, die so ausgebil det sind, dass eingeleitetes Gas einen zwischen dem Strahlungserzeuger und dem Strahlungssensor gebilde ten Strahlengang beeinflussen kann,
dadurch gekennzeichnet,
dass das Gehäuse mittels eines schalen- oder wannen förmigen, mit einer Öffnungsseite auf eine den Strah lungserzeuger und den Strahlungssensor tragende Lei terplatte (22) aufgesetzten Gehäuseelements (26) mit vorbestimmten Reflexionseigenschaften an seinen In nenwänden realisiert ist,
wobei ein bevorzugt nicht reflektierender Ober flächenabschnitt der Leiterplatte (22) das Gehäuseele ment verschließt.1. Device for preferably infrared optical gas measurement, with
one end of a radiation generator ( 16 ) provided by a housing ( 10 , 26 ) and a radiation sensor ( 20 ) provided opposite the end of the absorption path, which is followed by amplifier and / or detector electronics ( 28 ),
The housing is assigned means ( 12 ) for introducing gas ( 14 ) to be measured, which are designed such that introduced gas can influence a beam path formed between the radiation generator and the radiation sensor,
characterized by
that the housing is realized by means of a shell- or trough-shaped housing element ( 26 ) with an opening side on a radiation generator and the radiation sensor-carrying circuit board ( 22 ) with predetermined reflection properties on its inner walls,
a preferably non-reflecting surface section of the circuit board ( 22 ) closes the housing element.
