Definitions
- the flow chamber has at least two lateral, arranged between the lens and the reflector disc openings.
- the openings are chosen as large as possible.
- they occupy the predominant wall part of the through-channel between the viewing window and the reflector disk and are separated from each other only by narrow webs.
- the central body on the side facing away from the reflector disc of the lens has a coupling device for the reversible coupling of an optoelectronic sensor module.
- An optoelectronic sensor module is here understood to mean a structural unit which has a light source, a detector unit and suitable light-conducting elements.
- the light-guiding elements may be fiber-optic, but preferably of a beam-optical nature.
- fiber-optic light-conducting elements can have problems with regard to transparency, Dispersion, aperture, loss of fiber bends, etc. raise.
- the optoelectronic sensor module therefore preferably comprises an NIR light source, a purely or at least predominantly beam-optical illumination beam path comprising mirrors and optionally lenses, a likewise purely or at least predominantly radiolucent detection beam path, and an NIR detector, in particular an NIR spectrometer whose spectrometer input is definitely fiber-optic elements may contain. Due to the optical radiation supply and discharge of light, a positionally stable coupling between the sensor head and the optoelectronic sensor module is required. This requirement is met by said development of the invention due to the direct coupling with the central body. Corresponding coupling standards are known to the person skilled in the art, for example from microscopy.
- the central body does not necessarily have to be constructed in one piece. Rather, it is quite possible and often advantageous if the central body is constructed in several parts and has a main body and at least one other central body component. This can for example be realized so that the lens is sealingly supported between the main body and an end face of a clamping ring.
- the clamping ring can be fixed, for example, as a threaded ring, like a snap ring, by a latching or in a similar manner to the main body. Its object is to press the lens against a preferably provided with a seal projection of the passage channel to hold them on the one hand and on the other hand to seal.
- the clamping ring on its side facing away from the lens end face
- Coupling device for reversible coupling of the optoelectronic sensor module has.
- the clamping ring is thus assigned a dual function, namely on the one hand for holding and sealing the lens, as described above, and on the other hand as an adapter for the optoelectronic sensor module.
- a further realization of a multipart center body which may alternatively or preferably be implemented in addition to the aforementioned, is that the reflector disk is fixed on an adjusting plate, which is fixed at an adjustable distance from the lens on the main body.
- the adjusting plate may be formed as a body with external thread, which can be screwed into an internal thread at the outlet of the through-channel. Under cost aspects favorable and in the majority of practice-relevant cases probably sufficient will be a variant in which the adjustment plate and the main body have corresponding locking grooves and bulges.
- the adjusting plate may be provided with a circumferential detent groove or a peripheral detent bead which snaps into one of a plurality of mutually parallel, corresponding detent grooves or latching beads in the outlet-near inner wall of the through-channel.
- the sensor head geometry specifies several fixed positions for the adjustment plate, from which one can be chosen during assembly of the sensor head.
- this type of fixation of the adjusting plate is basically possible even with only one predetermined position.
- FIG. 2 shows a top view of the sensor head according to the invention along the line of sight arrow II in FIG. 1,
- clamping ring 24 and / or the main body 18 ahead is, if one or both of said elements, as preferably provided, are formed from a corresponding plastic.
- the clamping ring could for example also be provided with an external thread which can be screwed into an internal thread of the main body.
- the inner region of the through-channel 20 or the main body 18 can be subdivided into two subregions.
- the partial area next to the viewing window 14 is designed as a flow chamber 34.
- the main body 18 passing through openings 36 are provided which allow ontageendschreib a fluid exchange between the flow chamber 34 and the container interior.
- the flow chamber is closed by the reflector disc 14 opposite and substantially parallel to this reflector disc, which in turn is attached to an adjustment plate 26, for example, glued to this.
- the adjusting plate 26 has in the illustrated
- Embodiment a circumferential locking bead 38 which in one of two corresponding with him locking grooves 39 in the inner wall of the passageway 20 formed by the main body 18 is engaged.
- embodiments with only one latching groove 39, with more than two latching grooves 39 and with other fastening means are possible, for example an external thread on the adjusting plate 26, which can be screwed into an internal thread of the main body 18.
- the reflector disk 16 permanently fixed to the main body 18 in a non-adjustable manner.
- Figure 2 shows a plan view of the sensor head of Figure 1 according to the sighting arrow II, with reference to the above explained for explanation.
- FIG 3 shows a highly schematic sectional view of an optoelectronic sensor module, which forms an optical sensor together with the sensor head of Figures 1 and 2.
- the reflector disk 16 of the sensor head 10 is shown in addition to the optoelectronic sensor module 40.
- the optoelectronic sensor module 40 has a preferably dust and liquid-tight housing 42.
- an optical window 44 is embedded, which has sufficient for the intended measurement transparency in the respective required spectral range.
- NIR near Infrared Area
- a reflection flap 58 is provided in FIG. 3, which can be folded into the illumination beam path for calibration purposes, so that the light from the light source 48 is thrown onto the reflection flap via the mirror 50 and mirrored from there to the input 54 of the spectrometer 56 can be scattered.
- This direct measurement of the illumination light can be used to create a reference with which subsequently measured detection light of a transflection measurement can be compared.
- FIG. 4 shows the final assembly state of a disposable container 60 according to the invention.
- the container consists of a flexible bag 62 which is filled with a fluid 64.
- an agitator 66 projecting into the interior of the bag 64 is additionally provided, which maintains a permanent flow within the medium 64.
- the sensor head is used in the manner already described above. In particular, in the embodiment shown, it is welded to the outside of its mounting flange 22 against the inner wall of the bag 62.
- the flow chamber 34 is flowed through its openings 36 by the fluid 64, wherein the agitator 66 conveys the flow of "fresh" fluid, so that a measurement made on the volume of the flow chamber 34 can be taken as representative of the total bag contents of the sensor head 10 is the optoelectronic sensor module 40 coupled with the tri-clamp coupling structures 25/45 are held together by a clamp 70 in a standard manner.
- the coupling structures 25/45 are designed so that the optical window 44 is not parallel to the viewing window 14, but at a low angle, preferably between 1 degree and 3 degrees, particularly preferably 2 degrees lies, takes. As a result, errors are avoided, which can be caused by a reflection of the illumination light on the lens 14.
